Taking a DateTime and Comparing the Time

Question

I have a DateTime object with DateTime stored within it.

How would I take that DateTime and compare its time so I can check whether the time within that DateTime is greater, or less than 11:00:00 or 20:00:00 etc?

What about `.Hour`? – ProgrammingLlama Apr 17 '18 at 07:30 — ProgrammingLlama, Apr 17 '18 at 07:30

TimeOfDay is what you can use;

DateTime today = DateTime.Now;
TimeSpan timeCheck = (7,0,0)    //07:00 
If(today.TimeOfDay > timeCheck)
{
   //do something
}

or you could also use Hour that gets the hour component of the date in a way;

    DateTime today = DateTime.Now;
    If(today.Hour > 6)
    {
       //do something
    }

This looks like the right thing! My only concern is the timeCheck being (7,0,0) and commented as 7:00PM. How would I change it to AM or PM? – Izacch Apr 17 '18 at 07:36

You can try using TimeOfDay:

  DateTime source = DateTime.Now;

  if (source.TimeOfDay >= new TimeSpan(11, 0, 0) &&
      source.TimeOfDay <= new TimeSpan(20, 0, 0)) {
    ...
  }

@Tim Schmelter: I've put it just for generalization, when we want to check, say, `11:45` and `20:10`; in this particular case I agree that `source.Hour` is a better choice. – Dmitry Bychenko Apr 17 '18 at 07:37

Try the DateTime.CompareTo Method (DateTime).

Here is another approach.

        DateTime dt = DateTime.Now;
        int[] timeOnly = Array.ConvertAll(dt.ToString("HH:mm:ss").Split(':'), int.Parse);
        TimeSpan ts = new TimeSpan(timeOnly[0],timeOnly[1],timeOnly[2]);
          if (ts >= new TimeSpan(11, 0, 0) && ts <= new TimeSpan(20, 0, 0)) {
              Console.WriteLine("InBetween");
  }
        else
            Console.WriteLine(dt.ToString("HH:mm:ss"));
