CodeBehind Page-

protected void CalculateDate(object sender, EventArgs e)

{

string date1Day = this.txtDate1.Text.Remove(2);

string date2Day = this.txtDate2.Text.Remove(2);

string date1Month = this.txtDate1.Text.Substring(3, 2);

string date2Month = this.txtDate2.Text.Substring(3, 2);

string date1Year = this.txtDate1.Text.Substring(6);

string date2Year = this.txtDate2.Text.Substring(6);

DateTime d1 = Convert.ToDateTime(date1Month + "/" + date1Day + "/" + date1Year);

DateTime d2 = Convert.ToDateTime(date2Month + "/" + date2Day + "/" + date2Year);

if (d1 > d2)

{

ClientScript.RegisterStartupScript(this.GetType(), "Alert", "alert('Date1 is greater')", true);

}

else if (d1 == d2)

{

ClientScript.RegisterStartupScript(this.GetType(), "Alert", "alert('Both are same')", true);

}

else

{

ClientScript.RegisterStartupScript(this.GetType(), "Alert", "alert('Date2 is greater')", true);

}

}
Kindly accept the answer.

Hi,

Syntax :
```
public static int Compare( 
```
```
   DateTime t1, 
```
```
   DateTime t2 
```
```
)
```
```
Return Value
Type: System.Int32
A signed number indicating the relative values of t1 and t2.
```
```
Value Type Condition
Less than zero t1 is earlier than t2.
Zero t1 is the same as t2.
Greater than zero t1 is later than t2.
```
Example :

using System;

public class Example
{
   public static void Main()
   {
      DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
      DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
      int result = DateTime.Compare(date1, date2);
      string relationship;
      if (result < 0)
         relationship = "is earlier than";
      else if (result == 0)
         relationship = "is the same time as";
      else
         relationship = "is later than";
      Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
   }
}

// The example displays the following output:
// 8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM

Value Type	Condition
Less than zero	t1 is earlier than t2.
Zero	t1 is the same as t2.
Greater than zero	t1 is later than t2.
