Important noteImportant

Because this method uses culture-sensitive data, you should not assume that multiple calls to the method will return identical data unless provider is a CultureInfo object that represents the invariant culture. The data returned by this method can change if the user overrides the individual cultural settings of provider or if an update occurs to the system's cultural data for provider.

The following example demonstrates the GetDateTimeFormats(Char, IFormatProvider) method. It displays the string representations of a date using the short date format specifier ("d") for the fr-FR culture.

		DateTime july28 = new DateTime(2009, 7, 28, 5, 23, 15);
		
		IFormatProvider culture = 
			new System.Globalization.CultureInfo("fr-FR", true);
		// Get the short date formats using the "fr-FR" culture.
		string [] frenchJuly28Formats = 
					july28.GetDateTimeFormats('d', culture);

		// Display july28 in short date formats using "fr-FR" culture.
		foreach (string format in frenchJuly28Formats) {
			Console.WriteLine(format);
		}
      // The example displays the following output: 
      //       28/07/2009 
      //       28/07/09 
      //       28.07.09 
      //       28-07-09 
      //       2009-07-28
