YearMonthPattern Property

DateTimeFormatInfo.YearMonthPattern Property

Gets or sets the format pattern for a year and month value, which is associated with the "y" and "Y" format patterns.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public string YearMonthPattern { get; set; }

Property Value

Type: System.String
The format pattern for a year and month value, which is associated with the "y" and "Y" format patterns.

ExceptionCondition
ArgumentNullException

The property is being set to null.

InvalidOperationException

The property is being set and the DateTimeFormatInfo object is read-only.

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.

Your applications are recommended to set YearMonthPattern to the exact value of interest, instead of attempting to have the date separator replaced. For example, to obtain the pattern MM-yyyy, the application should set "MM-yyyy" specifically.

The following 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 );

   }

}

/*
