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

Syntax

'Declaration
Public Property ShortTimePattern As String

public string ShortTimePattern { get; set; }

Property Value

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

Exceptions

Exception	Condition
ArgumentNullException	An attempt was made to set the property to nulla null reference (Nothing in Visual Basic).
InvalidOperationException	The DateTimeFormatInfo object is read-only.

Remarks

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

Platform Notes

Silverlight for Windows Phone

DateTimeFormatInfo.ShortTimePattern values do not change when the clock is set to 24 hours. The property values should become "h:mm" but remain "h:mm tt" where tt is AM or PM.

Examples

The following example displays the value of ShortTimePattern 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.ShortTimePattern) & vbCrLf
   End Sub  
End Class 
' This example  produces the following output.
'       CULTURE    PROPERTY VALUE
'        en-US     h:mm tt
'        ja-JP     H:mm
'        fr-FR     HH:mm

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.ShortTimePattern) + "\n";
   }
}
