Examples

The following example instantiates a CultureInfo object for the en-US culture, changes its date separator to "-", and displays a date by using the "d", "G", and "g" standard format strings.

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.
