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

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

      DateTimeFormatInfo myDTFI = new CultureInfo( myCulture, false ).DateTimeFormat;
      Console.WriteLine( "  {0}     {1}", myCulture, myDTFI.YearMonthPattern );

注釈

プロパティYearMonthPatternは、メソッドDateTime.ToStringおよびDateTimeOffset.ToStringメソッドへの呼び出し、および "y" および "y" 標準書式指定文字列を提供する複合書式指定文字列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。The YearMonthPattern 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 "y" and "Y" standard format strings.

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

日付の区切り記号を使用する代わりに、年の月のパターンの日付の区切り記号を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 year month pattern to an exact string instead of using the date separator placeholder. たとえば、MM-yyyy というパターンを取得するには、年の月のパターンを "MM-yyyy" に設定します。For example, to get the pattern MM-yyyy, set the year month pattern to "MM-yyyy".
