C# syntax from VB: Datediff("yyyy"sDoBdate()) ?

Question

Hi I would like to calculate the age of a person given his/her birthdate. I'm doing this in C# and I had a really hard time finding the similar function like how VBScript used to do: Datediff(yyyysDoBdate()) when yyyy will give you the number of years. In my code: DateTime date1 = new DateTime(197211); //let's say the person's birthdate is 1/1/1972 TimeSpan TimeAlive = DateTime.Now - date1; Response.Write (TimeAlive); So I want to calculate how old he/she is from today's date. But so far I can only get the number of days. Is there another way? Thank so much!

Hi; When you use the Now method of the DateTime it you return an object with complete date and the hour from its computer. Try to use the ToString method passing a format that you are wanting like below. DateTime.Now.ToString(t); d it dates shortness D it dates long f Complete (it dates long + simple hour) F Complete (it dates long + complete hour) g generality (it dates shortness + simple hour) G generality (it dates shortness + complete hour) m M Day and Month (09 of February) r R Padrão RFC (Sun 09 Feb 2003 13:36:12 GMT) s Date and hour with information of the Zone of hourly Spindle t simple hour T complete date u Univesal with format U Univesal with complete format(complete date + complete hour) y Y Month/Year I wait that it helps you

See whether the Subtract() method of the DateTime class do your trick: http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemdatetimeclasssubtracttopic.asp?frame=true
