C# Formatting Age - Regarding Days, Weeks , Months - Years

Question

I am working on some medical software and I am required to output all ages in a very specific manner, based on the following rules:

 If under 6 Weeks old :           


        

Answer 1

You can get an object representing the user's current age with a simple subtraction:

TimeSpan age = DateTime.Now - dateOfBirth;

And then it's just a matter of doing a bunch of if clauses

if (age.TotalDays < 6 * 7) // 6 weeks
    // ...
else if (age.TotalDays < 6 * 30) // 6 months
    // ...
// et cetera

You should be able to figure out how to do your formatting.
