石头剪刀

学习C#已经有一段时间了，今天跟着老师学习了石头剪刀布，下面是自己写的石头剪刀布

            }

            int playerfist = pfist.ShowFist(strFist);
            Computer cfist = new Computer();
            int cpufist = cfist.ShowFist();
            switch (cpufist)
            {

                case 1: label4.Text = "石头"; break;
                case 2: label4.Text = "剪刀"; break;
                case 3: label4.Text = "布"; break;
            }
            label6.Text = Referee.Judge(playerfist, cpufist).ToString();

        }

      
    }
}

还是有点小小成就感的，主要利用面对对象的思想还是蛮重要的。

当然对于 出拳方式的处理，让  1--石头，2--剪刀 ，3--布  

对于裁判的判断，只进行  减法结果的判断进行这一点还是蛮巧妙的

玩家赢的结果有：1-2=-1,2-3=-1,3-1=2

平局只要减法结果为0

而剩下的便是电脑赢。
