Definition

Gets or sets the custom format string for a long date and long time value.

C#

Property Value

The custom format string for a long date and long time value.

Examples

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

C#
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.FullDateTimePattern );
   }
}

/*
This code produces the following output. Note that the exact output format depends on the OS, the OS version, and the native globalization library used by the OS.

 CULTURE    PROPERTY VALUE
  en-US     dddd, MMMM d, yyyy h:mm:ss tt
  ja-JP     yyyy年M月d日dddd H:mm:ss
  fr-FR     dddd d MMMM yyyy HH:mm:ss

Remarks

The "F" standard format string is an alias for the FullDateTimePattern property. In other words, the custom format string assigned to this property defines the format of the result string for the "F" standard format string. For more information, see Standard Date and Time Format Strings.

The value of the FullDateTimePattern property is generated dynamically by concatenating the LongDatePattern and LongTimePattern properties separated by a space. This dynamic assignment occurs under the following conditions:

  • If the property value is retrieved before it has been explicitly set.
  • When the value of the LongDatePattern property changes.
  • When the value of the LongTimePattern property changes.

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