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

Can you clarify what you are trying calculate? The difference between any two dates in C# or real life is a time span. If you are trying to calculate age then what you want is the timespan since their birth. Change Date2 to to

Timespan age = datenow - date1;
