Func delegate with no return type

All of the Func delegates return a value. What are the .NET delegates that can be used with methods that return void?

All Func delegates return something; all the Action delegates return void.

Func takes no arguments and returns TResult:

public delegate TResult Func()

Action takes one argument and does not return a value:

public delegate void Action(T obj)

Action is the simplest, 'bare' delegate:

public delegate void Action()

There's also Func and Action (and others up to 16 arguments). All of these (except for Action) are new to .NET 3.5 (defined in System.Core).
