次の例では、いくつかのカルチャの MonthDayPattern の値を表示します。The following example displays the value of MonthDayPattern 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->MonthDayPattern );
}

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.  The question marks take the place of native script characters.

CULTURE    PROPERTY VALUE
en-US     MMMM dd
ja-JP     M'?'d'?'
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 );
   }
}

注釈

MonthDayPattern プロパティは、DateTime.ToString および DateTimeOffset.ToString メソッドの呼び出しによって返される日付文字列のカルチャ固有の書式を定義します。また、"m" および "M" 標準書式指定文字列を指定する複合書式指定文字列によって返されます。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.

このプロパティは、Calendar プロパティの値が変更された場合に影響を受けます。This property is affected if the value of the Calendar property changes.

月と日のパターンの日付の区切り記号を、日付の区切り記号のプレースホルダーを使用するのではなく、正確な文字列に設定することをお勧めします。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. たとえば、MM-DD というパターンを取得するには、月と日のパターンを "MM-DD" に設定します。For example, to obtain the pattern MM-DD, set the month and day pattern to "MM-DD".
