C#: how do I subtract two dates?

Question

Here\'s my code:

DateTime date1 = new DateTime(byear, bmonth, bday, 0, 0, 0);
DateTime datenow =  DateTime.Now;
DateTime date2 = datenow - date1

Answer 1

The result of a date comparison is a TimeSpan, not a DateTime value.

You want to do this:

TimeSpan result = datenow - date1;
