C # delegate base 4--generic delegate Func

C # commissioned the basic series was originally published in February 2011 in my Sina blog, now it will be like this blog.

In order to facilitate development,. The net Base Class library provides several predefined delegates for the most commonly used scenarios in actual development, and these predefined delegates are used widely, such as when writing lambda expressions and developing parallel computing programs.

predefined generic delegate func

Class program
{
        double addint (int x, int y)
        {return
            x + y;
        }

        String AddString (string s1, string s2)
        {return
            s1 + s2;
        }

        static void Main (string[] args)
        {program
            p = new program ();

            When the first two arguments are int, they run a double, and the last parameter is consistent with the AddInt return value
            func<int, int, double> funcint = p.addint;
            Console.WriteLine ("Funcint value is {0}", funcint);

            Func<string, String, string> funcstring = p.addstring;
            Console.WriteLine ("Funcstring value is {0}", Funcstring ("AAA", "BBB"));
        }
