C# 委托(delegate) 的小例子

static void Main(string[] args)
        {
           Console.WriteLine(Exec(GetSet));
           Console.ReadKey();
        }
        //定义委托，用于将方法做为参数传给Exec.
        public delegate string GetResultDelegate();
        public static string Get()
        {
            return "get";
        }

        public static string GetTest()
        {
            return "gettest";
        }

        public static string GetSet()
        {
            return "getSet";
        }

        public static string Exec(GetResultDelegate getResult)
        {
            return getResult();
 }
