Property Value

Type: System.String

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

The SortableDateTimePattern property defines the culture-specific format of date strings that are returned by calls to the DateTime.ToString and DateTimeOffset.ToString methods and by composite format strings that are supplied the "s" standard format string.

The following example displays the value of SortableDateTimePattern 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.SortableDateTimePattern );



This code produces the following output.

  en-US     yyyy'-'MM'-'dd'T'HH':'mm':'ss
  ja-JP     yyyy'-'MM'-'dd'T'HH':'mm':'ss
  fr-FR     yyyy'-'MM'-'dd'T'HH':'mm':'ss
