Check if datetime instance falls in between other two datetime objects

Question

I would like to know a simple algorithm to check if the given instance of datetime lies between another two instances in C#.

Note:

I skimmed though this How do I check if a given datetime object is "between" two datetimes? and it was for python and many more for php. Most of the other questions were regarding difference between the two.

Details:

I am more specific about the time, date does not matter to me. For example i got DataBase entry for a staff who works between 10:00 Am - 9:00 Pm and I would like to know which staff is engaged in class at the given time like 2:00 Pm. Now this would return me the staff's details who are engaged at this time.

Edit

After accepting the answer(been more than year back), i realized i had incorrectly described the problem. But all i think that was to be done back then was to do date and time comparison. So answers by both Jason and VikciaR work.

Answer 1

DateTime.Ticks will account for the time. Use .Ticks on the DateTime to convert your dates into longs. Then just use a simple if stmt to see if your target date falls between.

// Assuming you know d2 > d1 if (targetDt.Ticks > d1.Ticks && targetDt.Ticks < d2.Ticks) {     // targetDt is in between d1 and d2 }
