Question

In C# 3.0, I’m doing the code below to declare a DateTime property and a int age property that is read only.

public class MyClass{
    public DateTime dateOfBirth{ get; set; }
    public int age { get; }

    public MyClass(){}

    public int CalculateAge(){}
}

But how can I get this updated age (that it’s read only) when someone enters his date of birth in a form, for example?

Answer 1

Don’t store the age, instead calculate it when get of the age property is executed:

public int Age { get { return 100; } }

But instead of returning 100, you do the calculation.
