示例

以下示例显示几个区域性的 的值 MonthDayPattern 。

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->MonthDayPattern );
}

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

fr-FR     d MMMM

*/

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.MonthDayPattern );
   }
}

/*

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.MonthDayPattern)

   End Sub

End Class

注解

属性 MonthDayPattern 定义通过调用 DateTime.ToString 和 DateTimeOffset.ToString 方法以及提供“m”和“M”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。

如果属性的值 Calendar 发生更改，则此属性将受到影响。

建议将月份和日期模式中的日期分隔符设置为确切的字符串，而不是使用日期分隔符占位符。 例如，若要获取模式 MM-DD，请将月和日模式设置为“MM-DD”。
