Event handlers and other callbacks are often invoked exclusively through delegates and never directly. Even so, it has thus far been necessary to place the code of event handlers and callbacks in distinct methods to which delegates are explictly created. In contrast, anonymous methods allow the code associated with a delegate to be written “in-line” where the delegate is used, conveniently tying the code directly to the delegate instance. Besides this convenience, anonymous methods have shared access to the local state of the containing function member. To achieve the same state sharing using named methods requires “lifting” local variables ..
