I have class A, B, C. They all can implicitly convert to a string

public static implicit operator A(string sz_) {  ... return sz; }

I have code that does this

object AClassWhichImplicitlyConvertsToString

{
    ...
    ((KnownType)(String)AClassWhichImplicitlyConvertsToString).KnownFunc()
}

The problem is, AClassWhichImplicitlyConvertsToString isnt a string even though it can be typecast into one implicitly. I get a bad cast exception. How do i say its ok as long as the class has an operator to convert into a string?
