Question

I don’t understand when to use the typeof() operator? In what context is it good to use it?

Answer 1

It is like .GetType() except it works on a type name instead of an instance.

You would use typeof(MyType) if you need to get an instance of System.Type and you know the type at compile time. You don’t need an instance of that type for resolve the description of that type (System.Type).

Eg if you had an instance you would:

object o = new MyType();
Type type = o.GetType()

But you could:

Type type = typeof(MyType)
