How do you compare DateTime objects using a specified tolerance in C#?

Question

By default C# compares DateTime objects to the 100ns tick. However, my database returns DateTime values to the nearest millisecond. What\'s the best way to compare two DateT

Answer 1

You need to remove the milliseconds component from the date object. One way is:

    DateTime d = DateTime.Now;
    d.Subtract(new TimeSpan(0, 0, 0, 0, d.Millisecond));

You can also subtract two datetimes

d.Subtract(DateTime.Now);

This will return a timespan object which you can use to compare the days, hours, minutes and seconds components to see the difference.
