How can I duplicate the F# discriminated union type in C#?

Question

I\'ve created a new class called Actor which processes messages passed to it. The problem I am running into is figuring out what is the most elegant way to pass related but

Answer 1

A long shot, but anyway..

I am assuming that discriminated-union is F# for ADT (Abstract Data Type). Which means the type could be one of several things.

In case there are two, you could try and put it in a simple generic class with two type parameters:

 public struct DiscriminatedUnion
 {   
      public DiscriminatedUnion(T1 t1) { value = t1; }
      public DiscriminatedUnion(T2 t1) { value = t2; }


      public static implicit operator T1(DiscriminatedUnion du) {return (T1)du.value; }
      public static implicit operator T2(DiscriminatedUnion du) {return (T2)du.value; }

      object value;
 }

To make it work for 3 or more, we need to replicate this class a number of times. Any one has a solution for function overloading depending on the runtime type?
