C# Winform学习--- 实现石头剪刀布的游戏

本文使用winform实现简单的石头剪刀布的游戏，主要实现，电脑随机出拳，玩家手动点击出拳；实现简易背景图片3秒切换；简易统计信息。

1、效果图

 

2.实现代码

新建一个windows窗体程序,用数字1代表石头，用数字2代表剪刀，用数字3代表布，结果取玩家和电脑出拳之差，有三种结果

• 玩家赢: -1，2
• 平手: 0
• 玩家输: 其它值

新建3个类：

1）Computer.cs 电脑随机出拳

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 石头剪刀布
{
    class Computer
    {

        public  string Fist
        {
            get;
            set;
        }


        public int ShowFist()
        {
            Random rnd = new Random();
            int fist = rnd.Next(1, 4);
            switch (fist)
            {
                case 1: Fist = "石头"; break;
                case 2: Fist = "剪刀"; break;
                case 3: Fist = "布"; break;
            }
            return fist;
        }

    }
}

2）、Judge.cs 裁判类 判断输赢

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 石头剪刀布
{

    class Judge
    {

        public enum RESULT
        {
            玩家赢,
            电脑赢,
            平手
        }

        public static RESULT WhoWin(int playerNum, int computerNum)
        {
            int result = playerNum - computerNum;
            if (result == -1 || result == 2)
            {
                return RESULT.玩家赢;
            }
            else if (result == 0)
            {
                return RESULT.平手;

            }
            else
            {
                return RESULT.电脑赢;
            }

        }

    }
}

3）、Player.cs 玩家，出拳

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 石头剪刀布
{
    class Player
    {
        public static int ShowFist(string fist)
        {
            switch (fist)
            {
                case "石头": return 1;
                case "剪刀": return 2;
                case "布": return 3;
                default: return 0;
            }
        }

    }
}

界面后台实现代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace 石头剪刀布
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        /// <summary>
        /// 点击石头按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnStone_Click(object sender, EventArgs e)
        {
            String fist = "石头";
            Game(fist);
        }
        /// <summary>
        /// 点击剪刀按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnScissors_Click(object sender, EventArgs e)
        {
            String fist = "剪刀";
            Game(fist);
        }
        /// <summary>
        /// 点击布按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnCloth_Click(object sender, EventArgs e)
        {
            String fist = "布";
            Game(fist);

        }

        //背景图片轮播
        String[] paths = Directory.GetFiles(@"C:workstone");//此目录里面必须有图片，否则会报错
        private void timer1_Tick(object sender, EventArgs e)
        {
            this.BackgroundImage = Image.FromFile(paths[new Random().Next(0, paths.Length)]);

        }
        static int playerWinTimes = 0;//玩家赢的次数
        static int gameTimes = 0;//总共次数
        static int tieTimes = 0;//平手次数

        /// <summary>
        /// 通用方法
        /// </summary>
        /// <param name="fist"></param>
        private void Game(String fist)
        {
            gameTimes++;
            lbPlayer.Text = fist;
            int playerNum = Player.ShowFist(fist);
            Computer cpu = new Computer();
            int cpuNum = cpu.ShowFist();
            lbComputer.Text = cpu.Fist;
            Judge.RESULT result = Judge.WhoWin(playerNum, cpuNum);
            lbJudge.Text = result.ToString();
            lbStatistics.Text = "统计信息：

1.您赢了" + playerWinTimes + "场比赛!

" + "2.平手了" + tieTimes + "次; 

" + "3.输掉了" + (gameTimes - playerWinTimes - tieTimes) + "场比赛; 

" + "4.共进行了" + gameTimes + "场比赛!

";

            if (result == Judge.RESULT.玩家赢)
            {
                playerWinTimes++;
                MessageBox.Show("恭喜，您已经赢了" + playerWinTimes + "场比赛！" + " 共进行了" + gameTimes + "场比赛！");
            }
            else if (result == Judge.RESULT.平手)
            {
                tieTimes++;
            }

        }

    }
}

实现游戏的难点在于要想到将石头剪刀布用数字来替换,如果逻辑通了实现起来并不难。
