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 SamplesDTFI
{
public static void Main()
{
string[] cultures = { "en-US", "ja-JP", "fr-FR" };
DateTime date1 = new DateTime(2011, 5, 1);
Console.WriteLine(" {0,7} {1,19} {2,10}\n", "CULTURE", "PROPERTY VALUE", "DATE");
foreach (var culture in cultures) {
DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture(culture).DateTimeFormat;
Console.WriteLine(" {0,7} {1,19} {2,10}", 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
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.
using System;
using System.Globalization;
public class Example
{
public static void Main()
{
DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat;
DateTime date1 = new DateTime(2011, 5, 1);
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));
}
}
// 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
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
Remarks
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.
