 property System::String ^ RFC1123Pattern { System::String ^ get(); };
public string RFC1123Pattern { get; }
member this.RFC1123Pattern : string
Public ReadOnly Property RFC1123Pattern As String

屬性值

根據 IETF RFC 1123 規格的時間值的自訂格式字串。The custom format string for a time value that is based on the IETF RFC 1123 specification.

範例

下列範例會顯示一些文化特性的 RFC1123Pattern 值。The following example displays the value of RFC1123Pattern for a few cultures.

using namespace System;
using namespace System::Globalization;
void PrintPattern( String^ myCulture )
{
   CultureInfo^ MyCI = gcnew CultureInfo( myCulture,false );
   DateTimeFormatInfo^ myDTFI = MyCI->DateTimeFormat;
   Console::WriteLine( " {0} {1}", myCulture, myDTFI->RFC1123Pattern );
}

int main()
{
   
   // Displays the values of the pattern properties.
   Console::WriteLine( " CULTURE    PROPERTY VALUE" );
   PrintPattern( "en-US" );
   PrintPattern( "ja-JP" );
   PrintPattern( "fr-FR" );
}

/*
This code produces the following output.

CULTURE    PROPERTY VALUE
en-US     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
ja-JP     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
fr-FR     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'

*/
using System;
using System.Globalization;


public class SamplesDTFI  {

   public static void Main()  {

      // Displays the values of the pattern properties.
      Console.WriteLine( " CULTURE    PROPERTY VALUE" );
      PrintPattern( "en-US" );
      PrintPattern( "ja-JP" );
      PrintPattern( "fr-FR" );

   }

   public static void PrintPattern( String myCulture )  {

      DateTimeFormatInfo myDTFI = new CultureInfo( myCulture, false ).DateTimeFormat;
      Console.WriteLine( "  {0}     {1}", myCulture, myDTFI.RFC1123Pattern );

   }

}

/*
This code produces the following output.

 CULTURE    PROPERTY VALUE
  en-US     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
  ja-JP     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
  fr-FR     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'

*/
Imports System.Globalization

Public Class SamplesDTFI

   Public Shared Sub Main()

      ' Displays the values of the pattern properties.
      Console.WriteLine(" CULTURE    PROPERTY VALUE")
      PrintPattern("en-US")
      PrintPattern("ja-JP")
      PrintPattern("fr-FR")

   End Sub

   Public Shared Sub PrintPattern(myCulture As [String])

      Dim myDTFI As DateTimeFormatInfo = New CultureInfo(myCulture, False).DateTimeFormat
      Console.WriteLine("  {0}     {1}", myCulture, myDTFI.RFC1123Pattern)

   End Sub

End Class

'This code produces the following output.
'
' CULTURE    PROPERTY VALUE
'  en-US     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
'  ja-JP     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'
'  fr-FR     ddd, dd MMM yyyy HH':'mm':'ss 'GMT'

備註

屬性會定義日期字串的特定文化特性格式,其由呼叫DateTime.ToStringDateTimeOffset.ToString方法,以及提供 "r" 和 "r" 標準格式字串的複合格式字串所傳回。 RFC1123PatternThe RFC1123Pattern property defines the culture-specific format of date strings that are returned by calls to the DateTime.ToString and DateTimeOffset.ToString methods and by composite format strings that are supplied the "r" and "R" standard format strings.

RFC1123 模式會反映已定義的標準,且屬性為唯讀。The RFC1123 pattern reflects a defined standard, and the property is read-only. 因此,無論文化特性為何,它一律是相同的。Therefore, it is always the same, regardless of the culture. 自訂格式字串為 "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'"。The custom format string is "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'".
