  平局那应该怎么写?  后面清平怎么把do上面四句话保留？还有按小写的n怎么没效果！最重要的怎么写可以不用输出一个字符按一下回车！

据说这程序用switch语句比较简单。。。但我不会用..

我也感觉到了不知道怎么改。。

我自学C#的。。。求指导

  //加载置顶信息
                CaiQuan.LoadHead();
                b = random.Next(3);
                //获取玩家输入
                char ch = Console.ReadKey().KeyChar;
                Console.WriteLine();
                //判断玩家输入是否合法
                if (Convert.ToInt32(ch) >= 48 && Convert.ToInt32(ch) <= 50)
                {
                    //将输入字符转换为整数
                    a = Convert.ToInt32(ch.ToString());
                    //判断输赢
                    int win = (b, a);
                    //输出结果
                    CaiQuan.print(c.ht[a].ToString(), c.ht[b].ToString(), win);
我能不能说这几句没看懂！虽然有注释..但这些语法我貌似没看过！

真心感谢你，写了这么多，辛苦了！

今天我试了下，面对对象来写我感觉不知道怎么下手。面对过程的话还会写个大概。
