ExceptionCondition

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

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.LongDatePattern );

   }

}
