示例

下面的示例显示了几个区域性的由 datetimeformatinfo.rfc1123pattern 的值。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'
'

注解

属性定义由对DateTime.ToStringDateTimeOffset.ToString方法的调用返回的特定于区域性的格式,以及通过提供 "r" 和 "r" 标准格式字符串的复合格式字符串返回的数据字符串。 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 模式反映了定义的标准,并且属性是只读的。The RFC1123 pattern reflects a defined standard, and the property is read-only. 因此,它始终是相同的,与区域性无关。Therefore, it is always the same, regardless of the culture. 定义格式字符串为“ddd, dd MMM yyyy HH':'mm':'ss 'GMT'”。The custom format string is "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'".
