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

As already mentioned, date - date gives you a TimeSpan, not a DateTime. If you want a DateTime, use AddDays(-1) as in:

DateTime subtractedDate = date1.AddDays(-1);
