Depends, you can create your own exception if you want. Take a look at
the exceptions deriving from either Exception or ApplicationException
to see if there is one that fits your case

Thanks but the question is if there is any kind of already defined
exception I should use in this case.

I'd look at ArgumentException. Though I'm not entirely clear from your
post whether it actually is an argument you're testing; if it's not you
might be better off creating your own derived Exception.

InvalidOperationException goes some of the way...

Hum,

Frankly I do not know. it would be nice to have a program that given a
type you get all the derived types and/or what types implement it.

Does anybody knows such a tool?
