call method in dynamic object?

Hi, i have some sort of Factory class which creates an instance of another class like so:

Code:

---

public object setDispatcher ( string obj )
{
        this.dispatcher = Activator.CreateInstance(Type.GetType(obj));
        return this.dispatcher;
}

//This is how i use the method
object disp = setDispatcher ( "MyClass" );

---

As parameter i gave the name of the Class which i want to instantiate. It works this far, because the constructor is called of the dynamically created class.

The instance of "MyClass" is now stored in the variable 'disp', but obviously i can't just do this:

disp.aMethod();

Because the compiler doesn't know what class i want to have and what methods it has. So there must be some other way to call the methods??

Anyone any advice on this??

This design pattern feels broken to me. I'm not sure why you would want to do this (i.e. use a factory to return an object instead of a typed class). Could you give some context as to what you are doing?

Also, the dumb answer is you should cast it to the object type...

Code:

---

object disp = setDispatcher ( "MyClass" );
MyClass myclassDisp = (MyClass)disp;
myclassDisp.methodCall();

---

... but I assume that isn't what you meant.
