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.
Imports System.Globalization
Public Class Example
Public Shared Sub Demo(outputBlock As System.Windows.Controls.TextBlock)
outputBlock.FontFamily = New System.Windows.Media.FontFamily("Courier New")
Dim cultures() As String = { "en-US", "ja-JP", "fr-FR" }
Dim date1 As Date = #05/01/2011#
outputBlock.Text += String.Format(" {0,7} {1,19} {2,10}",
"CULTURE", "PROPERTY VALUE", "DATE")
outputBlock.Text += vbCrLf + vbCrLf
For Each culture As String In cultures
Dim dtfi As DateTimeFormatInfo = (New CultureInfo(culture)).DateTimeFormat
outputBlock.Text += String.Format(" {0,7} {1,19} {2,10}", culture,
dtfi.ShortDatePattern,
date1.ToString("d", dtfi)) + vbCrLf
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
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.
Imports System.Globalization
Module Example
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim dtfi As DateTimeFormatInfo = (New CultureInfo("en-US")).DateTimeFormat
Dim date1 As DateTime = #5/1/2011#
outputBlock.Text &= "Original Short Date Pattern:" & vbCrLf
outputBlock.Text += String.Format(" {0}: {1}", dtfi.ShortDatePattern,
date1.ToString("d", dtfi)) & vbCrLf
dtfi.ShortDatePattern = "yyyy/MM/dd"
outputBlock.Text &= "Revised Short Date Pattern:" & vbCrLf
outputBlock.Text += String.Format(" {0}: {1}", dtfi.ShortDatePattern,
date1.ToString("d", dtfi)) & vbCrLf
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
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
