示例

以下示例显示几个区域性的值 YearMonthPattern

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->YearMonthPattern );
}

int main()
{

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

/*

 CULTURE    PROPERTY VALUE
  en-US     MMMM yyyy
  ja-JP     yyyy年M月
  fr-FR     MMMM yyyy

*/
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.YearMonthPattern );
   }
}

/*

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.YearMonthPattern)

   End Sub

End Class

'This code produces the following output.  The question marks take the place of native script characters.

注解

YearMonthPattern 属性定义通过调用 DateTime.ToStringDateTimeOffset.ToString 方法以及提供“y”和“Y”标准格式字符串的复合格式字符串返回的特定于区域性的日期字符串格式。

如果属性的值 Calendar 发生更改,则此属性将受到影响。

建议将年份月份模式中的日期分隔符设置为确切字符串,而不是使用日期分隔符占位符。 例如,若要获取模式 MM-yyyy,请将年份月份模式设置为“MM-yyyy”。
