Reflection - Get the list of method calls inside a lambda expression

Question

I am trying to find a way to get the list of method calls inside a lambda expression in C# 3.5. For instance, in the code below, I would like to method LookAtThis(Action a)

Answer 1

This is fairly easy as long as you use Expression instead of Action. For full code, including how to get the actual values implied, see here - in particular ResolveMethod (and how it is used by Invoke). This is the code I use in protobuf-net to do RPC based on lambdas.
