DateTimeFormatInfo.RFC1123Pattern 属性

定义

获取自定义的格式字符串,该字符串用于基于 Internet 工程任务组 (IETF) 征求意见文档 (RFC) 1123 规范的时间值。

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

属性值

基于 IETF RFC 1123 规范的时间值的自定义格式字符串。

示例

以下示例显示了几个区域性的 RFC1123Pattern 值。

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 );
   }
}

/*

  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'

注解

属性 RFC1123Pattern 定义通过调用 DateTime.ToStringDateTimeOffset.ToString 方法以及提供“r”和“R”标准格式字符串的复合格式字符串返回的日期字符串的区域性特定格式。

RFC1123模式反映定义的标准,并且 属性是只读的。 因此,无论区域性如何,它始终相同。 定义格式字符串为“ddd, dd MMM yyyy HH':'mm':'ss 'GMT'”。
