DateTimeFormatInfo.ShortDatePattern Property

Silverlight

Updated: December 2010

Gets or sets the custom date and time format string for a short date value, which is associated with the "d" standard format string.

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

Syntax

public string ShortDatePattern { get; set; }

Property Value

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

Exceptions

Exception	Condition
ArgumentNullException	An attempt was made to set the property to null.
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 "MM/dd/yyyy".

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

Examples

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.


using System;
using System.Globalization;

public class Example  
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)  
   {
      outputBlock.FontFamily = new System.Windows.Media.FontFamily("Courier New");
      string[]  cultures = { "en-US", "ja-JP", "fr-FR" };
      DateTime date1 = new DateTime(2011, 5, 1);

      outputBlock.Text += String.Format(" {0,7} {1,19} {2,10}\n\n", 
                                        "CULTURE", "PROPERTY VALUE", "DATE");

      foreach (var culture in cultures) {
         DateTimeFormatInfo dtfi = (new CultureInfo(culture)).DateTimeFormat;
         outputBlock.Text += String.Format(" {0,7} {1,19} {2,10}\n",
                                           culture, 
                                           dtfi.ShortDatePattern, 
                                           date1.ToString("d", dtfi));
      }
   }
}
// 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.


using System;
using System.Globalization;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      DateTimeFormatInfo dtfi = (new CultureInfo("en-US")).DateTimeFormat;
      DateTime date1 = new DateTime(2011, 5, 1);
      outputBlock.Text += "Original Short Date Pattern:" + "\n";
      outputBlock.Text += String.Format("   {0}: {1}", dtfi.ShortDatePattern,
                                       date1.ToString("d", dtfi)) + "\n";
      dtfi.ShortDatePattern = @"yyyy/MM/dd";
      outputBlock.Text += "Revised Short Date Pattern:" + "\n";
      outputBlock.Text += String.Format("   {0}: {1}", dtfi.ShortDatePattern,
                                       date1.ToString("d", dtfi)) + "\n";
   }
}
// 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
