DateTimeFormatInfo.UniversalSortableDateTimePattern Property

Gets the custom format string for a universal, sortable date and time string.

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

public string UniversalSortableDateTimePattern { get; }

Property Value

Type: System.String
The custom format string for a universal, sortable date and time string.

The UniversalSortableDateTimePattern property defines the 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 "u" standard format string. It can be used to display dates and times in a sortable order with the universal time designator "Z" at the end. The format is sortable because it uses leading zeros for year, month, day, hour, minute, and second. The custom format string ("yyyy'-'MM'-'dd HH':'mm':'ss'Z'") is the same regardless of culture or format provider.

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

   }

}

/*
