            list.AddBefore(last, "第三个人");

            LinkedListNode<String> second = list.Find("第二个人");
            list.AddAfter(second, "第二个人的跟班");


            //遍历方法01
            //while (first!= null) 
            //{

            //}

            //遍历方法02，可以迭代
            foreach (var item in list)
            {
                Console.WriteLine(item);
