using System;
using System.Globalization;

public class MainClass {
public static void Main(string[] args) {
DateTime dt = DateTime.Now;
String[] format = {
"d ", "D ",
"f ", "F ",
"g ", "G ",
"m ",
"r ",
"s ",
"t ", "T ",
"u ", "U ",
"y ",
"dddd, MMMM dd yyyy ",
"ddd, MMM d \ " '\ "yy ",
"dddd, MMMM dd ",
"M/yy ",
"dd-MM-yy ",
};
String date;
for (int i = 0; i < format.Length; i++) {
date = dt.ToString(format[i], DateTimeFormatInfo.InvariantInfo);
Console.WriteLine(String.Concat(format[i], " : " , date));
}

/** Output.
