You can pass in a Type reference of the type in question, which can then be created. Alternately you can use a string and then load from an assembly (but you have to know where the object lives or in the current assembly).
I'm not sure what you gain by this though. Why can't you just pass in the reference as an Object and return the result back out as an object? That way it's generic and your code inside only needs to cast to the proper object type as required.
