	char format


Type: System.Char

A standard date and time format string (see Remarks).

Return Value

Type: System.String[]
A string array where each element is the representation of the value of this instance formatted with the format standard date and time format specifier.


format is not a valid standard date and time format specifier character.

The format parameter can be any of the standard date and time format specifiers. These include "d", "D", "f", "F", "g", "G", "M" (or "m"), "O" (or "o"), "R" (or "r"), "s", "t", "T", "u", "U", and "Y" (or "y"). For more information, see Standard Date and Time Format Strings.

Each element of the return value is formatted using information from the current culture. For more information about culture-specific formatting information for the current culture, see CultureInfo.CurrentCulture.


   Because this method uses culture-sensitive data, your application should not assume that multiple calls to the method will return identical data. The data returned by this method can change if the current culture changes, the user overrides individual cultural settings, or an update occurs to the system's cultural data.

The following example demonstrates the GetDateTimeFormats(Char) method. It displays the string representation of a date using the long date format specifier ("D") for the current culture.

		DateTime july28 = new DateTime(2009, 7, 28, 5, 23, 15);
		// Get the long date formats using the current culture.
		string [] longJuly28Formats = 

		// Display july28 in all long date formats. 
		foreach (string format in longJuly28Formats) {
      // The example displays the following output: 
      //       Tuesday, July 28, 2009 
      //       July 28, 2009 
      //       Tuesday, 28 July, 2009 
      //       28 July, 2009
