What is the best way to log a .NET Func<>

I have a generic method that accepts a Func<int> and I would like to log the Func that is passed into the method. What properties are available on the passed in func to help me understand what it is doing?

As Jaroslav Jandek pointed out by using Expression<Func<T>> I can get more information about the method being passed in. Specifically: I found that the body property has the anonymous method signature as a string.

You can log the method name with func.Method.Name, and there's some other useful properties in the MethodInfo class. However, if the Func is anonymous, then you will not get a very helpful name.
