   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" );

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

Remarks

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.

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

We recommend that you set the date separator in the year month pattern to an exact string instead of using the date separator placeholder. For example, to get the pattern MM-yyyy, set the year month pattern to "MM-yyyy".
