//定义委托，它定义了可以代表的方法的类型      
    public delegate void GreetingDelegate(string name);
    class Program
    {
        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) 
        //也可以直接使用系统内置委托
        //private static void GreetPeople(string name, Action<string> MakeGreeting)
        { MakeGreeting(name); }             
       
        static void Main(string[] args)
