Is there a way to disable implicit casts from UInt32 to char?

Question

I am working on code that takes as input a ton of ascii text defined by specific protocol. The original author interpreted \"string(1)\" datatypes in the original protocol

Answer 1

As a "fix once" solution I think James Michael Hare's FxCop solution is the easiest.

To keep it from being a problem in the future refactoring to use a custom datatype instead of char so you can define the exact operations you want available may be a good idea.
