Checking if a type supports an implicit or explicit type conversion to another type with .NET

Question

Imagine you\'ve been given two System.Type\'s and you want to determine if there is an implicit or explicit type conversion from one to the other.

Answer 1

I don't think so. You'll have use reflection and look for those good ol' op_Implicit and op_Explicit static methods on each type.

This brings up the very interesting question: which has a greater performance impact, reflection (this answer) or using exceptions for control flow (Quartermeister's)? I honestly couldn't guess. You might want to profile each and find out for yourself.
