DateTimeFormatInfo.ShortDatePattern Property

Gets or sets the custom format string for a short date value.

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

'Declaration
Public Property ShortDatePattern As String

Property Value

Type: System.String
The custom format string for a short date value.

ExceptionCondition
ArgumentNullException

The property is being set to Nothing.

InvalidOperationException

The property is being set and the DateTimeFormatInfo object is read-only.

The ShortDatePattern 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 "d" standard format string.

This property is affected if the value of the Calendar property changes.

The following example displays the value of the ShortDatePattern property and the value of a date formatted using the ShortDatePattern property for a few cultures.

Imports System.Globalization

Public Class SamplesDTFI
   Public Shared Sub Main()
      Dim cultures() As String = { "en-US", "ja-JP", "fr-FR" }
      Dim date1 As Date = #05/01/2011#

      Console.WriteLine(" {0,7} {1,19} {2,10}", "CULTURE", "PROPERTY VALUE", "DATE")
      Console.WriteLine()

      For Each culture As String In cultures
         Dim dtfi As DateTimeFormatInfo = CultureInfo.CreateSpecificCulture(culture).DateTimeFormat
         Console.WriteLine(" {0,7} {1,19} {2,10}", culture, 
                           dtfi.ShortDatePattern, 
                           date1.ToString("d", dtfi))
      Next                      
   End Sub  
End Class 
' The example displays the following output: 
'        CULTURE      PROPERTY VALUE       DATE 
'        
'          en-US            M/d/yyyy   5/1/2011 
'          ja-JP          yyyy/MM/dd 2011/05/01 
'          fr-FR          dd/MM/yyyy 01/05/2011

The following example modifies the ShortDatePattern property of a DateTimeFormatInfo object that represents the formatting conventions of the English (United States) culture. It also displays a date value twice, first to reflect the original ShortDatePattern property and then to reflect the new property value.

Imports System.Globalization

Module Example
   Public Sub Main()
      Dim dtfi As DateTimeFormatInfo = CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat
      Dim date1 As DateTime = #05/01/2011#
      Console.WriteLine("Original Short Date Pattern:")
      Console.WriteLine("   {0}: {1}", dtfi.ShortDatePattern, 
                                       date1.ToString("d", dtfi))
      dtfi.DateSeparator = "-"
      dtfi.ShortDatePattern = "yyyy/MM/dd"
      Console.WriteLine("Revised Short Date Pattern:")
      Console.WriteLine("   {0}: {1}", dtfi.ShortDatePattern, 
                                       date1.ToString("d", dtfi))
   End Sub 
End Module 
' The example displays the following output: 
'    Original Short Date Pattern: 
'       M/d/yyyy: 5/1/2011 
'    Revised Short Date Pattern: 
'       YYYY/MM/dd: 2011-05-01
