' Determine if two method or property signatures match, using the rules in 4.1.1, i.e., ByRef mismatches,
' differences in optional parameters, custom modifiers, return type are not considered. An optional parameter
' matches if the corresponding parameter in the other signature is not there, optional of any type,
' or non-optional of matching type.
'
' Note that this sense of matching is not transitive. I.e.
' A) f(x as integer)
' B) f(x as integer, optional y as String = "")
' C) f(x as integer, y As String)
' A matches B, B matches C, but A doesn't match C
'
' Note that (A) and (B) above do match in terms of Dev10 behavior when we look for overridden
' methods/properties. We still keep this behavior in Roslyn to be able to generate the same
' error in the following case:
'
' Class Base
' Public Overridable Sub f(x As Integer)

' Public Overrides Sub f(x As Integer, Optional y As String = "")

'
' >>> error BC30308: 'Public Overrides Sub f(x As Integer, [y As String = ""])' cannot override
' 'Public Overridable Sub f(x As Integer)' because they differ by optional parameters.
'
' In this sense the method returns True if signatures match enough to be
' considered a candidate of overridden member.
'
' But for new overloading rules (overloading based on optional parameters) introduced in Dev11
' we also need more detailed info on the two members being compared, namely do their signatures
' also match taking into account total parameter count and parameter optionality (optional/required)?
' We return this information in 'exactMatch' parameter.
'
' So when searching for overridden members we prefer exactly matched candidates in case we could
' find them. This helps properly find overridden members in the following case:
'
' Class Base
' Public Overridable Sub f(x As Integer)
' End Sub
' Public Overridable Sub f(x As Integer, Optional y As String = "")

''' <summary>
''' Walk up the type hierarchy from ContainingType and list members that this
''' method overrides (accessible methods/properties with the same signature, if this
''' method is declared "override").
'''
''' Methods in the overridden list may not be virtual or may have different
''' accessibilities, types, accessors, etc. They are really candidates to be
''' overridden.
'''
''' All found accessible candidates of overridden members are collected in two
''' builders, those with 'exactly' matching signatures and those with 'generally'
''' or 'inexactly' matching signatures. 'Exact' signature match is a 'general'
''' signature match which also does not have mismatches in total number of parameters
''' and/or types of optional parameters. See also comments on correspondent
''' OverriddenMembersResult(Of TSymbol) properties.
'''
''' 'Inexactly' matching candidates are only collected for reporting Dev10/Dev11
''' errors like BC30697 and others. We collect 'inexact' matching candidates until
''' we find any 'exact' match.
'''
''' Also remembers inaccessible members that are found, but these do not prevent
''' continuing to search for accessible members.
'''
''' </summary>
''' <remarks>
''' In the presence of non-VB types, the meaning of "same signature" is rather
''' complicated. If this method isn't from source, then it refers to the runtime's
''' notion of signature (i.e. including return type, custom modifiers, etc).
''' If this method is from source, use the VB version of signature. Note that
''' Dev10 C# has a rule that prefers members with less custom modifiers. Dev 10 VB has no
''' such rule, so I'm not adding such a rule here.

Microsoft ResX Schema
Version 2.0
The primary goals of this format is to allow a simple XML format
that is mostly human readable. The generation and parsing of the
various data types are done through the TypeConverter classes
associated with the data types.
Example:
... ado.net/XML headers & schema ...
<resheader name="resmimetype">text/microsoft-resx</resheader>
<resheader name="version">2.0</resheader>
<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
<data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
<data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
<value>[base64 mime encoded serialized .NET Framework object]</value>
</data>
<data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
<comment>This is a comment</comment>
</data>
There are any number of "resheader" rows that contain simple
name/value pairs.
Each data row contains a name, and value. The row also contains a
type or mimetype. Type corresponds to a .NET class that support
text/value conversion through the TypeConverter architecture.
Classes that don't support this are serialized and stored with the
mimetype set.
The mimetype is used for serialized objects, and tells the
ResXResourceReader how to depersist the object. This is currently not
extensible. For a given mimetype the value must be set accordingly:
Note - application/x-microsoft.net.object.binary.base64 is the format
that the ResXResourceWriter will generate, however the reader can
read any of the formats listed below.
mimetype: application/x-microsoft.net.object.binary.base64
value : The object must be serialized with
: System.Serialization.Formatters.Binary.BinaryFormatter
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.net.object.soap.base64
value : The object must be serialized with
: System.Runtime.Serialization.Formatters.Soap.SoapFormatter
: and then encoded with base64 encoding.
mimetype: application/x-microsoft.net.object.bytearray.base64
value : The object must be serialized into a byte array
: using a System.ComponentModel.TypeConverter
: and then encoded with base64 encoding.

<source>Atomic groups (known in some other regular expression engines as a nonbacktracking subexpression, an atomic subexpression, or a once-only subexpression) disable backtracking. The regular expression engine will match as many characters in the input string as it can. When no further match is possible, it will not backtrack to attempt alternate pattern matches. (That is, the subexpression matches only strings that would be matched by the subexpression alone; it does not attempt to match a string based on the subexpression and any subexpressions that follow it.)
This option is recommended if you know that backtracking will not succeed. Preventing the regular expression engine from performing unnecessary searching improves performance.</source>
<target state="translated">Grupos atômicos (conhecidos em alguns outros mecanismos de expressão regulares como uma subexpressão sem rastreamento inverso, uma subexpressão atômica ou uma subexpressão de apenas uma vez) desabilita o rastreamento inverso. O mecanismo de expressão regular corresponderá o máximo possível de caracteres em uma cadeia de caracteres de entrada possível. Quando não for mais possível corresponder, ele não fará o rastreamento inverso para tentar alternar as correspondências de padrão. (Ou seja, a subexpressão corresponderá somente às cadeias de caracteres que seriam correspondidas pela subexpressão sozinha. Ela não tentará corresponder a uma cadeia de caracteres com base na subexpressão e nas subexpressões seguintes.)
Essa opção é recomendada quando você sabe que o rastreamento inverso não será bem-sucedido. Impedir o mecanismo de expressão regular de executar pesquisas desnecessárias melhora o desempenho.</target>

<source>A balancing group definition deletes the definition of a previously defined group and stores, in the current group, the interval between the previously defined group and the current group.
'name1' is the current group (optional), 'name2' is a previously defined group, and 'subexpression' is any valid regular expression pattern. The balancing group definition deletes the definition of name2 and stores the interval between name2 and name1 in name1. If no name2 group is defined, the match backtracks. Because deleting the last definition of name2 reveals the previous definition of name2, this construct lets you use the stack of captures for group name2 as a counter for keeping track of nested constructs such as parentheses or opening and closing brackets.
The balancing group definition uses 'name2' as a stack. The beginning character of each nested construct is placed in the group and in its Group.Captures collection. When the closing character is matched, its corresponding opening character is removed from the group, and the Captures collection is decreased by one. After the opening and closing characters of all nested constructs have been matched, 'name1' is empty.</source>
<target state="translated">Uma definição de grupo de balanceamento exclui a definição de um grupo definido anteriormente e armazena, no grupo atual, o intervalo entre o grupo definido anteriormente e o grupo atual.
'name1' é o grupo atual (opcional), 'name2' é um grupo definido anteriormente e 'subexpression' é qualquer padrão de expressão regular válido. A definição de grupo de balanceamento exclui a definição de name2 e armazena o intervalo entre name2 e name1 no name1. Se não for definido nenhum name2, a correspondência retrocederá. Como a exclusão da última definição de name2 revela a definição anterior de name2, esse constructo permite o uso da pilha de capturas para o grupo name2 como um contador para manter o controle de constructos aninhados, como parênteses ou colchetes de abertura e fechamento.
A definição de grupo de balanceamento usa 'name2' como uma pilha. O caractere inicial de cada constructo aninhado é colocado no grupo e em sua coleção Group.Captures. Quando o caractere de fechamento é correspondido, seu caractere de abertura correspondente é removido do grupo e a coleção Captures é reduzida em um. Após a correspondência dos caracteres de abertura e fechamento de todas as construções aninhadas, 'name1' ficará vazio.</target>

At the beginning of a regular expression, it can define a specific pattern that should not be matched when the beginning of the regular expression defines a similar but more general pattern to be matched.

It defines a substring that must be found at the end of a string for a match to occur but that should not be included in the match. It is also useful for preventing excessive backtracking.

For example, the custom format string mm'/'dd'/'yyyy produces a result string in which "/" is always used as the date separator. To change the date separator for all dates for a culture, either change the value of the DateTimeFormatInfo.DateSeparator property of the current culture, or instantiate a DateTimeFormatInfo object, assign the character to its DateSeparator property, and call an overload of the formatting method that includes an IFormatProvider parameter.

Para alterar o separador de data para todas as datas para uma cultura, altere o valor da propriedade DateTimeFormatInfo.DateSeparator da cultura atual ou crie uma instância de um objeto DateTimeFormatInfo, atribua o caractere à sua propriedade DateSeparator e chame uma sobrecarga do método de formatação que inclui um parâmetro IFormatProvider.

<trans-unit id="round_trip_date_time_description">
<source>The "O" or "o" standard format specifier represents a custom date and time format string using a pattern that preserves time zone information and emits a result string that complies with ISO 8601. For DateTime values, this format specifier is designed to preserve date and time values along with the DateTime.Kind property in text. The formatted string can be parsed back by using the DateTime.Parse(String, IFormatProvider, DateTimeStyles) or DateTime.ParseExact method if the styles parameter is set to DateTimeStyles.RoundtripKind.
The "O" or "o" standard format specifier corresponds to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" custom format string for DateTime values and to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffzzz" custom format string for DateTimeOffset values. In this string, the pairs of single quotation marks that delimit individual characters, such as the hyphens, the colons, and the letter "T", indicate that the individual character is a literal that cannot be changed. The apostrophes do not appear in the output string.
The "O" or "o" standard format specifier (and the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" custom format string) takes advantage of the three ways that ISO 8601 represents time zone information to preserve the Kind property of DateTime values:
The time zone component of DateTimeKind.Local date and time values is an offset from UTC (for example, +01:00, -07:00). All DateTimeOffset values are also represented in this format.
The time zone component of DateTimeKind.Utc date and time values uses "Z" (which stands for zero offset) to represent UTC.
DateTimeKind.Unspecified date and time values have no time zone information.
Because the "O" or "o" standard format specifier conforms to an international standard, the formatting or parsing operation that uses the specifier always uses the invariant culture and the Gregorian calendar.
Strings that are passed to the Parse, TryParse, ParseExact, and TryParseExact methods of DateTime and DateTimeOffset can be parsed by using the "O" or "o" format specifier if they are in one of these formats. In the case of DateTime objects, the parsing overload that you call should also include a styles parameter with a value of DateTimeStyles.RoundtripKind. Note that if you call a parsing method with the custom format string that corresponds to the "O" or "o" format specifier, you won't get the same results as "O" or "o". This is because parsing methods that use a custom format string can't parse the string representation of date and time values that lack a time zone component or use "Z" to indicate UTC.</source>
<target state="translated">O especificador de formato padrão "O" ou "o" representa uma cadeia de caracteres de formato de data e hora personalizado usando um padrão que preserva as informações de fuso horário e emite uma cadeia de resultado que está em conformidade com o ISO 8601. Para valores DateTime, esse especificador de formato é projetado para preservar valores de data e hora juntamente com a propriedade DateTime.Kind no texto. A cadeia de caracteres formatada poderá ser analisada novamente usando o método DateTime.Parse (String, IFormatProvider, DateTimeStyles) ou DateTime.ParseExact se o parâmetro styles estiver definido como DateTimeStyles.RoundtripKind.
O especificador de formato padrão "O" ou "o" corresponde à cadeia de caracteres de formato personalizado "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" para valores DateTime e à cadeia de caracteres de formato personalizado "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffzzz" para valores de DateTimeOffset. Nessa cadeia de caracteres, os pares de aspas simples que delimitam caracteres individuais, como hifens, dois-pontos e a letra "T", indicam que o caractere individual é um literal que não pode ser alterado. Os apóstrofos não aparecem na cadeia de caracteres de saída.
O especificador de formato padrão "O" ou "o" (e a cadeia de caracteres de formato personalizado "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK") aproveita as três maneiras pelas quais o ISO 8601 representa as informações de fuso horário para preservar a propriedade Kind dos valores DateTime:
O componente de fuso horário de DateTimeKind.Local dos valores de data e hora é uma diferença do UTC (por exemplo, +01:00, -07:00). Todos os valores de DateTimeOffset também são representados nesse formato.
O componente de fuso horário de DateTimeKind.Utc dos valores de data e hora usa "Z" (que significa diferença zero) para representar o UTC.
Os valores de data e hora de DateTimeKind.Unspecified não especificados não têm informações de fuso horário.
Como o especificador de formato padrão "O" ou "o" está em conformidade com um padrão internacional, a operação de formatação ou análise que usa o especificador sempre usa a cultura invariável e o calendário gregoriano.
As cadeias de caracteres que são passadas para os métodos Parse, TryParse, ParseExact e TryParseExact de DateTime e DateTimeOffset podem ser analisadas usando o especificador de formato "O" ou "o" caso elas estejam em um desses formatos. No caso de objetos DateTime, a sobrecarga de análise que você chama também deve incluir um parâmetro styles com um valor de DateTimeStyles.RoundtripKind. Observe que, se você chamar um método de análise com a cadeia de caracteres de formato personalizado que corresponde ao especificador de formato "O" ou "o", você não obterá os mesmos resultados de "O" ou "o". Isso porque os métodos de análise que usam uma cadeia de caracteres de formato personalizado não podem analisar a representação de cadeia de caracteres dos valores de data e hora que não têm um componente de fuso horário ou usar "Z" para indicar o UTC.</target>

<source>The "u" standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo.UniversalSortableDateTimePattern property. The pattern reflects a defined standard, and the property is read-only. Therefore, it is always the same, regardless of the culture used or the format provider supplied. The custom format string is "yyyy'-'MM'-'dd HH':'mm':'ss'Z'". When this standard format specifier is used, the formatting or parsing operation always uses the invariant culture.
Although the result string should express a time as Coordinated Universal Time (UTC), no conversion of the original DateTime value is performed during the formatting operation. Therefore, you must convert a DateTime value to UTC by calling the DateTime.ToUniversalTime method before formatting it.</source>
<target state="translated">O especificador de formato padrão "u" representa uma cadeia de caracteres de formato personalizado de data e hora que é definida pela propriedade DateTimeFormatInfo.UniversalSortableDateTimePattern. O padrão reflete um padrão definido e a propriedade é somente leitura. Portanto, é sempre o mesmo, independentemente da cultura usada ou do provedor de formato fornecido. A cadeia de caracteres de formato personalizado é "yyyy'-'MM'-'dd HH':'mm':'ss'Z'". Quando esse especificador de formato padrão é usado, a operação de análise ou formatação sempre usa a cultura invariável.
Embora a cadeia de caracteres de resultado deva expressar um horário como UTC (Tempo Universal Coordenado), nenhuma conversão do valor original DateTime é executada durante a operação de formatação. Portanto, você precisa converter um valor DateTime para UTC chamando o método DateTime.ToUniversalTime antes de formatá-lo.</target>

In a parsing operation, a two-digit year that is parsed using the "yy" custom format specifier is interpreted based on the Calendar.TwoDigitYearMax property of the format provider's current calendar. The following example parses the string representation of a date that has a two-digit year by using the default Gregorian calendar of the en-US culture, which, in this case, is the current culture. It then changes the current culture's CultureInfo object to use a GregorianCalendar object whose TwoDigitYearMax property has been modified.</source>

Em uma operação de análise, um ano de dois dígitos analisado usando o especificador de formato personalizado "yy" é interpretado com base na Propriedade Calendar.TwoDigitYearMax do calendário atual do provedor de formato. O exemplo a seguir analisa a representação de cadeia de caracteres de uma data que tem um ano de dois dígitos usando o calendário gregoriano padrão da cultura en-US, que, neste caso, é a cultura atual. Em seguida, altera o objeto CultureInfo da cultura atual para usar um objeto GregorianCalendar cuja propriedade TwoDigitYearMax foi modificada.</target>

O designador AM é usado para todos os horários de 0:00:00 (meia-noite) até 11:59:59.999. O designador PM é usado para todos os horários de 12:00:00 (meio-dia) até 23:59:59.999.
Verifique se o especificador "tt" foi usado para idiomas para os quais é necessário manter a distinção entre AM e PM. Um exemplo é o japonês, para o qual os designadores AM e PM diferem no segundo caractere, em vez de no primeiro caractere.</target>

<source>Atomic groups (known in some other regular expression engines as a nonbacktracking subexpression, an atomic subexpression, or a once-only subexpression) disable backtracking. The regular expression engine will match as many characters in the input string as it can. When no further match is possible, it will not backtrack to attempt alternate pattern matches. (That is, the subexpression matches only strings that would be matched by the subexpression alone; it does not attempt to match a string based on the subexpression and any subexpressions that follow it.)
This option is recommended if you know that backtracking will not succeed. Preventing the regular expression engine from performing unnecessary searching improves performance.</source>
<target state="translated">Grupos atômicos (conhecidos em alguns outros mecanismos de expressão regulares como uma subexpressão sem rastreamento inverso, uma subexpressão atômica ou uma subexpressão de apenas uma vez) desabilita o rastreamento inverso. O mecanismo de expressão regular corresponderá o máximo possível de caracteres em uma cadeia de caracteres de entrada possível. Quando não for mais possível corresponder, ele não fará o rastreamento inverso para tentar alternar as correspondências de padrão. (Ou seja, a subexpressão corresponderá somente às cadeias de caracteres que seriam correspondidas pela subexpressão sozinha. Ela não tentará corresponder a uma cadeia de caracteres com base na subexpressão e nas subexpressões seguintes.)
Essa opção é recomendada quando você sabe que o rastreamento inverso não será bem-sucedido. Impedir o mecanismo de expressão regular de executar pesquisas desnecessárias melhora o desempenho.</target>

<source>A balancing group definition deletes the definition of a previously defined group and stores, in the current group, the interval between the previously defined group and the current group.
'name1' is the current group (optional), 'name2' is a previously defined group, and 'subexpression' is any valid regular expression pattern. The balancing group definition deletes the definition of name2 and stores the interval between name2 and name1 in name1. If no name2 group is defined, the match backtracks. Because deleting the last definition of name2 reveals the previous definition of name2, this construct lets you use the stack of captures for group name2 as a counter for keeping track of nested constructs such as parentheses or opening and closing brackets.
The balancing group definition uses 'name2' as a stack. The beginning character of each nested construct is placed in the group and in its Group.Captures collection. When the closing character is matched, its corresponding opening character is removed from the group, and the Captures collection is decreased by one. After the opening and closing characters of all nested constructs have been matched, 'name1' is empty.</source>
<target state="translated">Uma definição de grupo de balanceamento exclui a definição de um grupo definido anteriormente e armazena, no grupo atual, o intervalo entre o grupo definido anteriormente e o grupo atual.
'name1' é o grupo atual (opcional), 'name2' é um grupo definido anteriormente e 'subexpression' é qualquer padrão de expressão regular válido. A definição de grupo de balanceamento exclui a definição de name2 e armazena o intervalo entre name2 e name1 no name1. Se não for definido nenhum name2, a correspondência retrocederá. Como a exclusão da última definição de name2 revela a definição anterior de name2, esse constructo permite o uso da pilha de capturas para o grupo name2 como um contador para manter o controle de constructos aninhados, como parênteses ou colchetes de abertura e fechamento.
A definição de grupo de balanceamento usa 'name2' como uma pilha. O caractere inicial de cada constructo aninhado é colocado no grupo e em sua coleção Group.Captures. Quando o caractere de fechamento é correspondido, seu caractere de abertura correspondente é removido do grupo e a coleção Captures é reduzida em um. Após a correspondência dos caracteres de abertura e fechamento de todas as construções aninhadas, 'name1' ficará vazio.</target>

The \b anchor is frequently used to ensure that a subexpression matches an entire word instead of just the beginning or end of a word.</source>
<target state="translated">A âncora \b especifica que a correspondência precisa ocorrer em um limite entre um caractere de palavra (o elemento de linguagem \w) e um caractere que não seja de palavra (o elemento de linguagem \W). Os caracteres de palavra consistem em caracteres alfanuméricos e sublinhados; um caractere que não é de palavra é qualquer caractere que não é alfanumérico nem sublinhado. A correspondência também pode ocorrer em um limite de palavra no início ou no fim da cadeia de caracteres.
A âncora \b é usada geralmente para garantir que uma subexpressão corresponda a uma palavra inteira em vez de apenas ao início ou ao fim de uma palavra.</target>

<source>A zero-width negative lookahead assertion, where for the match to be successful, the input string must not match the regular expression pattern in subexpression. The matched string is not included in the match result.
A zero-width negative lookahead assertion is typically used either at the beginning or at the end of a regular expression. At the beginning of a regular expression, it can define a specific pattern that should not be matched when the beginning of the regular expression defines a similar but more general pattern to be matched. In this case, it is often used to limit backtracking. At the end of a regular expression, it can define a subexpression that cannot occur at the end of a match.</source>

A cadeia de caracteres correspondente não está incluída no resultado correspondente.
Uma asserção lookahead negativa de largura zero normalmente é usada no início ou no final de uma expressão regular. No início de uma expressão regular, ela pode definir um padrão específico que não deve ser correspondido quando o início da expressão regular define um padrão semelhante, mas mais geral, a ser correspondido. Nesse caso, ela geralmente é usada para limitar o rastreamento inverso. No final de uma expressão regular, ela pode definir uma subexpressão que não pode ocorrer no final de uma correspondência.</target>

Zero-width negative lookbehind assertions are typically used at the beginning of regular expressions. The pattern that they define precludes a match in the string that follows.

As declarações de lookbehind negativas de largura zero normalmente são usadas no início de expressões regulares. O padrão que elas definem impede uma correspondência na cadeia de caracteres seguinte.

Typically, a zero-width positive lookahead assertion is found at the end of a regular expression pattern. It defines a substring that must be found at the end of a string for a match to occur but that should not be included in the match. It is also useful for preventing excessive backtracking. You can use a zero-width positive lookahead assertion to ensure that a particular captured group begins with text that matches a subset of the pattern defined for that captured group.</source>

A substring correspondente não é incluída no resultado correspondente. Uma asserção lookahead positiva de largura zero não retrocede.
Normalmente, uma asserção lookahead positiva de largura zero é encontrada no final de um padrão de expressão regular. Ela define uma substring que precisa ser encontrada no final de uma cadeia de caracteres para que uma correspondência ocorra, mas que não deve ser incluída na correspondência. Ela também é útil para impedir o rastreamento inverso excessivo. Você pode usar uma asserção lookahead positiva de largura zero para garantir que um determinado grupo capturado comece com um texto que corresponda a um subconjunto do padrão definido para esse grupo capturado.</target>

For example, the custom format string mm'/'dd'/'yyyy produces a result string in which "/" is always used as the date separator. To change the date separator for all dates for a culture, either change the value of the DateTimeFormatInfo.DateSeparator property of the current culture, or instantiate a DateTimeFormatInfo object, assign the character to its DateSeparator property, and call an overload of the formatting method that includes an IFormatProvider parameter.

Por exemplo, a cadeia de caracteres de formato personalizado mm'/'dd'/'yyyy produz uma cadeia de resultado na qual "/" é sempre usado como separador de data. Para alterar o separador de data para todas as datas para uma cultura, altere o valor da propriedade DateTimeFormatInfo.DateSeparator da cultura atual ou crie uma instância de um objeto DateTimeFormatInfo, atribua o caractere à sua propriedade DateSeparator e chame uma sobrecarga do método de formatação que inclui um parâmetro IFormatProvider.

<trans-unit id="round_trip_date_time_description">
<source>The "O" or "o" standard format specifier represents a custom date and time format string using a pattern that preserves time zone information and emits a result string that complies with ISO 8601. For DateTime values, this format specifier is designed to preserve date and time values along with the DateTime.Kind property in text. The formatted string can be parsed back by using the DateTime.Parse(String, IFormatProvider, DateTimeStyles) or DateTime.ParseExact method if the styles parameter is set to DateTimeStyles.RoundtripKind.
The "O" or "o" standard format specifier corresponds to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" custom format string for DateTime values and to the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffzzz" custom format string for DateTimeOffset values. In this string, the pairs of single quotation marks that delimit individual characters, such as the hyphens, the colons, and the letter "T", indicate that the individual character is a literal that cannot be changed. The apostrophes do not appear in the output string.
The "O" or "o" standard format specifier (and the "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" custom format string) takes advantage of the three ways that ISO 8601 represents time zone information to preserve the Kind property of DateTime values:
The time zone component of DateTimeKind.Local date and time values is an offset from UTC (for example, +01:00, -07:00). All DateTimeOffset values are also represented in this format.
The time zone component of DateTimeKind.Utc date and time values uses "Z" (which stands for zero offset) to represent UTC.
DateTimeKind.Unspecified date and time values have no time zone information.
Because the "O" or "o" standard format specifier conforms to an international standard, the formatting or parsing operation that uses the specifier always uses the invariant culture and the Gregorian calendar.
Strings that are passed to the Parse, TryParse, ParseExact, and TryParseExact methods of DateTime and DateTimeOffset can be parsed by using the "O" or "o" format specifier if they are in one of these formats. In the case of DateTime objects, the parsing overload that you call should also include a styles parameter with a value of DateTimeStyles.RoundtripKind. Note that if you call a parsing method with the custom format string that corresponds to the "O" or "o" format specifier, you won't get the same results as "O" or "o". This is because parsing methods that use a custom format string can't parse the string representation of date and time values that lack a time zone component or use "Z" to indicate UTC.</source>
<target state="translated">O especificador de formato padrão "O" ou "o" representa uma cadeia de caracteres de formato de data e hora personalizado usando um padrão que preserva as informações de fuso horário e emite uma cadeia de resultado que está em conformidade com o ISO 8601. Para valores DateTime, esse especificador de formato é projetado para preservar valores de data e hora juntamente com a propriedade DateTime.Kind no texto. A cadeia de caracteres formatada poderá ser analisada novamente usando o método DateTime.Parse (String, IFormatProvider, DateTimeStyles) ou DateTime.ParseExact se o parâmetro styles estiver definido como DateTimeStyles.RoundtripKind.
O especificador de formato padrão "O" ou "o" corresponde à cadeia de caracteres de formato personalizado "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK" para valores DateTime e à cadeia de caracteres de formato personalizado "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffzzz" para valores de DateTimeOffset. Nessa cadeia de caracteres, os pares de aspas simples que delimitam caracteres individuais, como hifens, dois-pontos e a letra "T", indicam que o caractere individual é um literal que não pode ser alterado. Os apóstrofos não aparecem na cadeia de caracteres de saída.
O especificador de formato padrão "O" ou "o" (e a cadeia de caracteres de formato personalizado "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffffffK") aproveita as três maneiras pelas quais o ISO 8601 representa as informações de fuso horário para preservar a propriedade Kind dos valores DateTime:
O componente de fuso horário de DateTimeKind.Local dos valores de data e hora é uma diferença do UTC (por exemplo, +01:00, -07:00). Todos os valores de DateTimeOffset também são representados nesse formato.
O componente de fuso horário de DateTimeKind.Utc dos valores de data e hora usa "Z" (que significa diferença zero) para representar o UTC.
Os valores de data e hora de DateTimeKind.Unspecified não especificados não têm informações de fuso horário.
Como o especificador de formato padrão "O" ou "o" está em conformidade com um padrão internacional, a operação de formatação ou análise que usa o especificador sempre usa a cultura invariável e o calendário gregoriano.
As cadeias de caracteres que são passadas para os métodos Parse, TryParse, ParseExact e TryParseExact de DateTime e DateTimeOffset podem ser analisadas usando o especificador de formato "O" ou "o" caso elas estejam em um desses formatos. No caso de objetos DateTime, a sobrecarga de análise que você chama também deve incluir um parâmetro styles com um valor de DateTimeStyles.RoundtripKind. Observe que, se você chamar um método de análise com a cadeia de caracteres de formato personalizado que corresponde ao especificador de formato "O" ou "o", você não obterá os mesmos resultados de "O" ou "o". Isso porque os métodos de análise que usam uma cadeia de caracteres de formato personalizado não podem analisar a representação de cadeia de caracteres dos valores de data e hora que não têm um componente de fuso horário ou usar "Z" para indicar o UTC.</target>

Para os valores de DateTimeOffset, o especificador de formato "K" é equivalente ao especificador de formato "zzz" e produz uma cadeia de caracteres de resultado contendo o deslocamento do valor de DateTimeOffset do UTC.
Se o especificador de formato "K" for usado sem outros especificadores de formato personalizado, ele será interpretado como um especificador de formato padrão de data e hora e gerará uma FormatException.</target>

<source>The "u" standard format specifier represents a custom date and time format string that is defined by the DateTimeFormatInfo.UniversalSortableDateTimePattern property. The pattern reflects a defined standard, and the property is read-only. Therefore, it is always the same, regardless of the culture used or the format provider supplied. The custom format string is "yyyy'-'MM'-'dd HH':'mm':'ss'Z'". When this standard format specifier is used, the formatting or parsing operation always uses the invariant culture.
Although the result string should express a time as Coordinated Universal Time (UTC), no conversion of the original DateTime value is performed during the formatting operation. Therefore, you must convert a DateTime value to UTC by calling the DateTime.ToUniversalTime method before formatting it.</source>
<target state="translated">O especificador de formato padrão "u" representa uma cadeia de caracteres de formato personalizado de data e hora que é definida pela propriedade DateTimeFormatInfo.UniversalSortableDateTimePattern. O padrão reflete um padrão definido e a propriedade é somente leitura. Portanto, é sempre o mesmo, independentemente da cultura usada ou do provedor de formato fornecido. A cadeia de caracteres de formato personalizado é "yyyy'-'MM'-'dd HH':'mm':'ss'Z'". Quando esse especificador de formato padrão é usado, a operação de análise ou formatação sempre usa a cultura invariável.
Embora a cadeia de caracteres de resultado deva expressar um horário como UTC (Tempo Universal Coordenado), nenhuma conversão do valor original DateTime é executada durante a operação de formatação. Portanto, você precisa converter um valor DateTime para UTC chamando o método DateTime.ToUniversalTime antes de formatá-lo.</target>

With DateTimeOffset values, this format specifier represents the DateTimeOffset value's offset from UTC in hours and minutes.

With DateTimeOffset values, this format specifier represents the DateTimeOffset value's offset from UTC in hours.
The offset is always displayed with a leading sign. A plus sign (+) indicates hours ahead of UTC, and a minus sign (-) indicates hours behind UTC. A single-digit offset is formatted without a leading zero.
If the "z" format specifier is used without other custom format specifiers, it's interpreted as a standard date and time format specifier and throws a FormatException.</source>

Com os valores de DateTimeOffset, este especificador de formato representa o deslocamento do valor de DateTimeOffset do UTC em horas.
O deslocamento é sempre exibido com um sinal à esquerda. Um sinal de adição (+) indica horas à frente do UTC e um sinal de subtração (-) indica horas atrás do UTC. Um deslocamento de dígito único é formatado sem um zero à esquerda.

In a parsing operation, a two-digit year that is parsed using the "yy" custom format specifier is interpreted based on the Calendar.TwoDigitYearMax property of the format provider's current calendar. The following example parses the string representation of a date that has a two-digit year by using the default Gregorian calendar of the en-US culture, which, in this case, is the current culture. It then changes the current culture's CultureInfo object to use a GregorianCalendar object whose TwoDigitYearMax property has been modified.</source>

Em uma operação de análise, um ano de dois dígitos analisado usando o especificador de formato personalizado "yy" é interpretado com base na Propriedade Calendar.TwoDigitYearMax do calendário atual do provedor de formato. O exemplo a seguir analisa a representação de cadeia de caracteres de uma data que tem um ano de dois dígitos usando o calendário gregoriano padrão da cultura en-US, que, neste caso, é a cultura atual. Em seguida, altera o objeto CultureInfo da cultura atual para usar um objeto GregorianCalendar cuja propriedade TwoDigitYearMax foi modificada.</target>
