            string Name = Console.ReadLine();
            Console.WriteLine(ds(Name));

            };
            Console.WriteLine(“———————-“);
            Console.WriteLine(“请输入用户名:”);
            string WriteName = Console.ReadLine();
            Console.WriteLine(ds2(WriteName));
            Console.WriteLine(“———————-“);

//Lambada委托

            DeleteShow ds3 = (LamName) => { return string.Format(“Lambada委托—-输入的用户名为:{0}”, LamName); };
            Console.WriteLine(“———————-“);
            Console.WriteLine(“请输入用户名:”);
            string WriteLamName = Console.ReadLine();
            Console.WriteLine(ds3(WriteLamName));
            Console.WriteLine(“———————-“);
