use the Compare() method to compare DateTime instances

     
using System;

class MainClass {

    public static void Main() {
        DateTime myDateTime = DateTime.Now;
        DateTime myDateTime2 = DateTime.UtcNow;
        DateTime myDateTime3 = new DateTime(2004, 1, 13);
        DateTime myDateTime4 = new DateTime(2004, 1, 14);
        Console.WriteLine("myDateTime3 = " + myDateTime3);
        Console.WriteLine("myDateTime4 = " + myDateTime4);
        int intResult = DateTime.Compare(myDateTime3, myDateTime4);
        Console.WriteLine("DateTime.Compare(myDateTime3,myDateTime4) = " + DateTime.Compare(myDateTime, myDateTime2));

    }
}
