Formatting Dates

A format specifier can quickly convert a DateTime object into a properly formatted value string:

 DateTime dateOutput = new DateTime( 2001, 1, 1 ); Console.WriteLine( "{0:d} [" + string.Format( "{0:d}", dateOutput ) + "]" ); 

Table C-2 describes how to format dates that take a DateTime object of January 1, 2001.
