using System;
using System.Globalization;
public class Example
{
public static void Main()
{
DateTime value = new DateTime(2013, 9, 8);
string[] formats = { "d", "G", "g" };
CultureInfo culture = CultureInfo.CreateSpecificCulture("en-US");
DateTimeFormatInfo dtfi = culture.DateTimeFormat;
dtfi.DateSeparator = "-";
foreach (var fmt in formats)
Console.WriteLine("{0}: {1}", fmt, value.ToString(fmt, dtfi));
}
}
// The example displays the following output:
// d: 9-8-2013
// G: 9-8-2013 12:00:00 AM
// g: 9-8-2013 12:00 AM
Imports System.Globalization
Module Example
Public Sub Main()
Dim value As New Date(2013, 9, 8)
Dim formats() As String = { "d", "G", "g" }
Dim culture As CultureInfo = CultureInfo.CreateSpecificCulture("en-US")
Dim dtfi As DateTimeFormatInfo = culture.DateTimeFormat
dtfi.DateSeparator = "-"
For Each fmt In formats
Console.WriteLine("{0}: {1}", fmt, value.ToString(fmt, dtfi))
Next
End Sub
End Module
' The example displays the following output:
' d: 9-8-2013
' G: 9-8-2013 12:00:00 AM
' g: 9-8-2013 12:00 AM
Remarks
If a custom format string includes the "/" format specifier, the DateTime.ToString method displays the value of DateSeparator in place of the "/" in the result string.
The DateSeparator property defines the string that replaces the date separator ("/" custom date and time format specifier) in a result string in a formatting operation. It also defines the date separator string in a parsing operation.
