Property Value

Type: System.String
The custom format string for a long time value, which is associated with the "T" standard format string.


An attempt was made to set the property to null.


The DateTimeFormatInfo object is read-only.

See Custom Date and Time Format Strings for custom date and time format specifiers that can be combined to form custom date and time strings, such as "HH:mm:ss".

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

using System;
using System.Globalization;

public class Example
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
      // Displays the values of the pattern properties.
      outputBlock.Text += " CULTURE    PROPERTY VALUE" + "\n";
      PrintPattern(outputBlock, "en-US");
      PrintPattern(outputBlock, "ar-EG");
      PrintPattern(outputBlock, "fr-FR");

   public static void PrintPattern(System.Windows.Controls.TextBlock outputBlock, String myCulture)
      DateTimeFormatInfo myDTFI = new CultureInfo(myCulture).DateTimeFormat;
      outputBlock.Text += String.Format("  {0}     {1}", myCulture, myDTFI.LongTimePattern) + "\n";
This example produces the following output.
//      en-US     h:mm:ss tt
//      ar-EG     hh:mm:ss tt
//      fr-FR     HH:mm:ss
