Question

I’ve written a class that looks like this:

public class MyClass<T>
{
    public void doSomething()
    {
       T.somethingSpecial;
    }
}

This code doesn’t compile because the compiler has no idea what T is. I would like to constrain T so that it must inherit a certain class that defines somethingSpecial. Bonus points if you can tell me how to do the same thing by contraining T so that it must implement a certain interface.

Answer 1

public class MyClass<T> where T: IAmSomethingSpecial

It’s called Constraints on Type Parameters.
