Calculate nearest age by birth date in c#

Question

I want to calculate the age based on birth date and it should rounded to the nearest i.e. 19/03/1988 would be resultant into 26 and 19/09/1988 to 25.

Below is the current implementation.

var ts = DateTime.Now - dtBirthdate;
var age = ts.Days / 365;

When does your current implementation give you incorrect result? — Konrad Morawski, Dec 03 '13 at 09:32
What problems have you observed in the current implementation? Does it crash? Does it throw an exception? Does it work? It it doesn't, how do its results compare to the expected ones? — Daniel Daranas, Dec 03 '13 at 09:33
Above code is calculating the age but not the nearest, As per the birth date 19/03/1988, the age should be 26 not 25. — Dhaval Panchal, Dec 03 '13 at 09:58
@AndrewKim: The link you have provided is not calculating the nearest age too. — Dhaval Panchal, Dec 03 '13 at 09:59

The problem with your current implementation is integer division. If you replace with a double, it should work better:

var ts = DateTime.Now - new DateTime(1988, 3, 19);
var age = Math.Round(ts.Days / 365.0);
