如何比较Firsttime endTime和当前时间之间的两个Time？

Question

Can any one describe me how compare two given time with current time?

I have Start time 11 AM and End time 1PM. I have timer to tick only when time hour between 11AM to 1PM every day.

I have below code but its not working fine Please check.

TimeSpan StartHit = new TimeSpan(11, 0, 0);
TimeSpan EndHit = new TimeSpan(1, 0, 0);
if (DateTime.Now.TimeOfDay >= StartHit && DateTime.Now.TimeOfDay <= EndHit)
{
     //my task here
}

Answer 1

You need to use 13 as an hour, not 1 in your EndHit .

TimeSpan StartHit = new TimeSpan(11, 0, 0);
TimeSpan EndHit = new TimeSpan(13, 0, 0);
if (DateTime.Now.TimeOfDay >= StartHit && DateTime.Now.TimeOfDay <= EndHit)
{
   //my task here
}

TimeOfDay property represents the time interval that has elapsed since midnight . If you use 1 as an hour, it will be 1 AM not 1 PM .

And of course, a TimeSpan doesn't keep these values as 1 AM or 1 PM , these are just string representation of them. It keeps them as an integer values as 1 and 13 .

Answer 2

Use

TimeSpan EndHit = new TimeSpan(13, 0, 0);

TimeSpan(1, 0, 0) is for 1 AM

Answer 3

this code should be working fine:

 DateTime time1 = DateTime.Now;
 DateTime time2 = Convert.ToDateTime("11:00:00 AM");
 DateTime time3 = Convert.ToDateTime("1:00:00 PM");

 if (DateTime.Compare(time1, time3) < 0 && DateTime.Compare(time1, time2) > 0)
 {
 }

For example for DateTime.Compare(time1, time3), if Time1 > time3 it return 1, if time1 < time3 it returns -1 and if time1 = time3 it returns 0. I hope this is helpful.
