Continuing with the general theme of Func<>, Action<> and generics here is a nice little trick to replace long but simple switch statements with a generic dictionary and a Func statement.

It's a more elegant solution, I wonder how it effects the MSIL generated by the compiler? Generally switch statements translate to a series of equality checks, or a dictionary lookup depending on the size of the statement.

I didn't get chance to do the MSIL stuff over the weekend but if you were thinking about speed issues then there are a couple of comments on the post which might be interesting to you.
