Assembly: mscorlib (in mscorlib.dll)

public string LongDatePattern { get; set; }
/** @property */

Property Value

The format pattern for a long date value, which is associated with the "D" format pattern.

Exception typeCondition

ArgumentNullException

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

InvalidOperationException

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

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

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

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 );

   }

}
