C Sharp Generic delegates Func, Action and Predicate with anonymous method

In .net 3.5 some new generic delegates -Func<T>, Action<T> and Predicate<T> were introduced. Using generic delegates, it is possible to concise delegate type means you don’t have to define the delegate statement. These delegates are the Func<T>, Action<T> and Predicate<T> delegates and defined in the System namespace. Action<T> performs an operation on the generic arguments.
