委托-将方法作为方法的参数

//定义委托,它定义了可以代表的方法的类型
        public delegate void GreetingDelegate(string name);
        private static void EnglishGreeting(string name)
        {
            Console.WriteLine("Morning, " + name);
        }

        private static void ChineseGreeting(string name)
        {
            Console.WriteLine("早上好, " + name);
        }

        //注意此方法,它接受一个GreetingDelegate类型的方法作为参数
        private static void GreetPeople(string name, GreetingDelegate MakeGreeting)
        {
            MakeGreeting(name);
        }

        static void Main(string[] args)
        {
            GreetPeople("Jimmy Zhang", EnglishGreeting);
            GreetPeople("张子阳", ChineseGreeting);
            Console.ReadKey();
        }
