Examples

The following example displays the value of MonthDayPattern for a few cultures.

C#
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 );
   }
}

/*
This code produces the following output. Note that the exact output format depends on the OS, the OS version, and the native globalization library used by the OS.

 CULTURE    PROPERTY VALUE
  en-US     MMMM d
  ja-JP     M月d日
  fr-FR     d MMMM

*/

Remarks

The MonthDayPattern 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 "m" and "M" standard format strings.

This property is affected if the value of the Calendar property changes.

We recommend that you set the date separator in the month and day pattern to an exact string instead of using the date separator placeholder. For example, to obtain the pattern MM-DD, set the month and day pattern to "MM-DD".
