DateTimeFormatInfo.UniversalSortableDateTimePattern Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the custom date and time format string for a universal sortable date and time value, which is associated with the "u" standard format string.

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

Syntax

'Declaration
Public ReadOnly Property UniversalSortableDateTimePattern As String

public string UniversalSortableDateTimePattern { get; }

Property Value

Type: System.String
The custom format string for a universal sortable date and time value, which is associated with the "u" standard format string.

Remarks

UniversalSortableDateTimePattern can be used to display time in a sortable format 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 string ("yyyy'-'MM'-'dd HH':'mm':'ss'Z'") is the same regardless of culture or format provider.

Examples

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

Imports System.Globalization

Public Class Example
   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Displays the values of the pattern properties.
      outputBlock.Text &= " CULTURE    PROPERTY VALUE" & vbCrLf
      PrintPattern(outputBlock, "en-US")
      PrintPattern(outputBlock, "ja-JP")
      PrintPattern(outputBlock, "fr-FR")
   End Sub 

   Public Shared Sub PrintPattern(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal myCulture As [String])
      Dim myDTFI As DateTimeFormatInfo = New CultureInfo(myCulture).DateTimeFormat
      outputBlock.Text += String.Format("  {0}     {1}", myCulture, myDTFI.UniversalSortableDateTimePattern) & vbCrLf
   End Sub  
End Class 
' This example produces the following output.
'       CULTURE    PROPERTY VALUE
'        en-US     yyyy'-'MM'-'dd HH':'mm':'ss'Z'
'        ja-JP     yyyy'-'MM'-'dd HH':'mm':'ss'Z'
'        fr-FR     yyyy'-'MM'-'dd HH':'mm':'ss'Z'

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, "ja-JP");
      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.UniversalSortableDateTimePattern) + "\n";
   }
}
