how to display message box in label click using function

check following code

You can use the TimeOfDay property and use the Compare against it.
DateTime Curtime = DateTime.Now;
DateTime lbltime= Convert.ToDateTime(Label1.Text);
int result=TimeSpan.Compare(Curtime.TimeOfDay, lbltime.TimeOfDay)
if(result==1)
{
//show your msg
}

the result returns:
-1 if Curtime is shorter than lbltime.
0 if Curtime is equal to lbltime.
1 if Curtime is longer than lbltime

Hi,
  You can do this as shown below

  DateTime t1 = DateTime.Now;

 DateTime t2 = Convert.ToDateTime("8:00:00 AM");

 int diff = TimeSpan.Compare(t1.TimeOfDay, t2.TimeOfDay);

 if (diff == 1)

 {

   MessageBox.Show("Time is Over");

 }
