多播委托+遍历委托链

namespace Delegate1
{
    class Game
    {
        public int Shout(string gamename)
        {
            Console.WriteLine(gamename + "真好玩");
            return 111;
        }
        public int Beat(string gamename)
        {
            Console.WriteLine(gamename + "通关了");
            return 222;
        }
    }
    public delegate int GameDelegate(string a);
    class Program
    {
        static void Main(string[] args)
        {
            Game game = new Game();
            GameDelegate gameDelegate = new GameDelegate(game.Shout);
            //gameDelegate("之狼");
            gameDelegate += game.Beat;
            int k = gameDelegate.Invoke("之狼");
            Console.WriteLine("委托里的值是" + k);

            //遍历委托链
            foreach (GameDelegate i in gameDelegate.GetInvocationList())
            {
                Console.WriteLine("委托里的值是" + i.Invoke("之狼"));
            }

            Console.ReadLine();
        }
    }
