Using lambda expressions with TPL and LINQ

There are several methods in TPL that take a System.Func<TResult> or System.Action delegate as an input parameter. These can be used to pass custom logic into a task, query, or parallel loop. Inline blocks can be used when creating delegates.

Use Func delegates to encapsulate methods that return a value and use Action delegates to encapsulate methods that do not return values. Let’s review the following example:

        static void FuncAction()

        {

            int[] numbers = { 15, 10, 12, 17, 11, 13, 16, 

                14, 18 };

            int additionResult = 0;
