C # Compare size of two dates two case resolution

Method 1:

Datetime.compare (T1,T2) compares two date size, row front small, row in the back big , for example: 2011-2-1 is less than 2012-3-2
The return value is less than 0: T1 is less than T2.
The return value equals zero: T1 equals T2.
The return value is greater than 0: T1 is greater than T2.

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");}}    

Method 2.

Using system;using system.collections;public class myclass{public static void Main () {DateTime dt1 = DateTime.Parse ("2006 -04-01 ");D atetime DT2 = DateTime.Parse (" 2006-05-01 "); TimeSpan ts = dt2. Subtract (DT1); Console.WriteLine (TS. Totaldays); Console.ReadLine ();}}

System.TimeSpan diff1 = Date2. Subtract (date1);
This method can be used to specify the difference in value
Subtract two datetime directly, the result is a timespan, so that you can take the timespan of days and other properties
