How to calculate the age of a certain person in C #?

I have a datetime variable that represents the user's date of birth.

How can I get age in years from this?

Update I want an exact birthday, so 30.45 years or something like that.

Answer 1

Try the following (assuming the date of birth is stored in dtDOB ):

 public int getAgeInYears { TimeSpan tsAge = DateTime.Now.Subtract(dtDOB); return new DateTime(tsAge.Ticks).Year - 1; } 

Answer 2

Stolen from the answer to Jeff's question:

 DateTime now = DateTime.Now; int age = now.Year - bday.Year; if (now < bday.AddYears(age)) age--; 

Answer 3

You can try (in Vb):

  Dim dateOfBirth As Date Now.Subtract(dateOfBirth).TotalDays \ 365 

\ is a whole division in Vb, I don't know if it has in C #.
