The return value is equal to zero: T1 equals T2.
The return value is greater than 0: T1 is greater than T2.

Such as:
Using System; Using System.Collections.Generic; Using System.Linq; Using System.Text; Namespace ConsoleApplication1 {class Program {static void Main (string[] args) {DateTime T1 = datetime.parse ("2011-2-2") ; DateTime t2 = datetime.parse ("2011-3-1"); if (Datetime.compare (t1, T2) > 0) Console.WriteLine ("T1 > t2"); if (Datetime.compare (t1, t2) = = 0) Console.WriteLine ("T1 = = t2"); if (Datetime.compare (t1, T2) < 0) Console.WriteLine ("T1 < T2"); } } }
