Anything. If it's a reference type and doesn't override Equals/
GetHashCode then you'll only get an identity look-up (unless you
specify a separate IEqualityComparer), and it's generally a bad idea
to use mutable types as keys, but that's it really.

Hello!

But how is that done if a class is used as a key?

What do you mean? Why would you expect it not to work?

//Tony- Hide quoted text -

Dictionary allows object as key, I think while retrieving the value
from dictionary, it uses HashCode of the object.

Anything fishey or you are expecting a BUG in baseclass library?

Do you mean class as in typeof(someClass)?
