C#實現的幾種委托方式介紹

代碼如下：

//普通委托
            DeleteShow ds = new DeleteShow(ShowName);
            Console.WriteLine("----------------------");
            Console.WriteLine("普通委托----請輸入用戶名:");
            string Name = Console.ReadLine();
            Console.WriteLine(ds(Name));
            Console.WriteLine("----------------------");

//匿名方法委托

            DeleteShow ds2 = delegate(string NewName) {
                return string.Format("匿名方法委托----輸入的用戶名為:{0}", NewName);
            };
            Console.WriteLine("----------------------");
            Console.WriteLine("請輸入用戶名:");
            string WriteName = Console.ReadLine();
            Console.WriteLine(ds2(WriteName));
            Console.WriteLine("----------------------");

//Lambada委托

            DeleteShow ds3 = (LamName) => { return string.Format("Lambada委托----輸入的用戶名為:{0}", LamName); };
            Console.WriteLine("----------------------");
            Console.WriteLine("請輸入用戶名:");
            string WriteLamName = Console.ReadLine();
            Console.WriteLine(ds3(WriteLamName));
            Console.WriteLine("----------------------");
