Table 3.3 lists
the
valid format specifiers supported by the Format
method on the DateTime
type (see
System.IFormattable
).
Table C-3. DateTime Format Specifiers
Here’s an example that uses these custom format specifiers on a
DateTime
value:
using System; class TestDateTimeFormats { static void Main( ) { DateTime dt = new DateTime(2000, 10, 11, 15, 32, 14); // Prints "2000-10-11T15:32:14" Console.WriteLine(dt.ToString( )); // Prints "Wednesday, October 11, 2000" Console.WriteLine("{0}", dt); // Prints "10/11/2000" Console.WriteLine("{0:d}", dt); // Prints "Wednesday, October 11, 2000" Console.WriteLine("{0:D}", dt); // Prints "Wednesday, October 11, 2000 3:32 PM" Console.WriteLine("{0:f}", dt); // Prints "Wednesday, October 11, 2000 3:32:14 PM" Console.WriteLine("{0:F}", dt); // Prints "10/11/2000 3:32 PM" Console.WriteLine("{0:g}", dt); // Prints "10/11/2000 3:32:14 PM" Console.WriteLine("{0:G}", dt); // Prints "October 11" Console.WriteLine("{0:m}", dt); // Prints "October 11" Console.WriteLine("{0:M}", dt); // Prints "Wed, 11 Oct 2000 22:32:14 GMT" Console.WriteLine("{0:r}", dt); // Prints "Wed, 11 Oct 2000 22:32:14 GMT" Console.WriteLine("{0:R}", dt); // Prints "3:32 PM" Console.WriteLine("{0:t}", dt); // Prints "3:32:14 PM" Console.WriteLine("{0:T}", dt); // Prints "2000-10-11 22:32:14Z" Console.WriteLine("{0:u}", dt); // Prints "Wednesday, October 11, 2000 10:32:14 PM" Console.WriteLine("{0:U}", dt); // Prints "October, 2000" Console.WriteLine("{0:y}", dt); // Prints "October, 2000" Console.WriteLine("{0:Y}", dt); // Prints "Wednesday the 11 day of October in the year 2000" Console.WriteLine( "{0:dddd 'the' d 'day of' MMMM 'in the year' yyyy}", dt); } }
