Question

I have this class structure :

class A     {   }
class B:A   {   }

A x = new B();

this is the runtime type :

x.GetType(); //B

How can i get its compile time type ?

I tried typeof (x) – but the argument has to be a type…

my desire answer is : A

edit

why am i asking it ?

cause i think int is inistialized via polymorphic engine :

something like this :

object myInd = new Int32(); / /this DOES compile 

and i want to verify my assumption :

does it come from object ?

and in order to do it – i have to know its static type….

Answer 1

You can create a generic method:

Type StaticTypeOf<T>(T t)
{
  return typeof(T);
}

To call it:

object i = 1;

// Writes out System.Object
Console.WriteLine(StaticTypeOf(i).ToString());

It’s a solution – even though I don’t see what the problem solved with the solution is 😉
