关于委派的返回值

•委派返回值为其函数列表中最后一个调用的返回值，不过一般我们不会去关心它。
简单示例如下：
#region Using directives

•using System;

•using System.Collections.Generic;

•using System.Text;

•#endregion

•namespace ConsoleApplication3

•{

•    class Program

•    {

•        delegate string DelegateTest(string input);

•        static void Main(string[] args)

•        {

•            DelegateTest din = new DelegateTest(Test1);

•            din += new DelegateTest(Test2);

•            string rlt = din("123");

•            Console.WriteLine(rlt);

•            Console.ReadLine();

•        }

•        static string Test1(string inp)

•        {

•            Console.WriteLine("Test1");

•            return "test1";

•        }

•        static string Test2(string inp)

•        {

•            Console.WriteLine("Test2");

•            return "test2";

•        }

•    }

•}
