Exception typeCondition

ArgumentNullException

The property is being set to a null reference (Nothing in Visual Basic).

See DateTimeFormatInfo for patterns that can be combined to construct custom patterns; for example, "yyyy MMMM".

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

The following code example displays the value of YearMonthPattern 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.YearMonthPattern );

   }

}

/*
