新建一個windows窗體程序,用數字1代表石頭，用數字2代表剪刀，用數字3代表布，結果取玩家和電腦出拳之差，有三種結果
玩家贏: -1，2
平手: 0
玩家輸: 其它值
新建3個類：
1）Computer.cs 電腦隨機出拳
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace 石頭剪刀布
{
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 = "石頭"; break;
case 2: Fist = "剪刀"; break;
case 3: Fist = "布"; break;
}
return fist;
}
}
}
2）、Judge.cs 裁判類 判斷輸贏
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace 石頭剪刀布
{
class Judge
{
public enum RESULT
{
玩家贏,
電腦贏,
平手
}
public static RESULT WhoWin(int playerNum, int computerNum)
{
int result = playerNum - computerNum;
if (result == -1 || result == 2)
{
return RESULT.玩家贏;
}
else if (result == 0)
{
return RESULT.平手;
}
else
{
return RESULT.電腦贏;
}
}
}
}
3）、Player.cs 玩家，出拳
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace 石頭剪刀布
{
class Player
{
public static int ShowFist(string fist)
{
switch (fist)
{
case "石頭": return 1;
case "剪刀": return 2;
case "布": return 3;
default: return 0;
}
}
}
}
界面後臺實現代碼：
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 石頭剪刀布
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
/// <summary>
/// 點擊石頭按鈕
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnStone_Click(object sender, EventArgs e)
{
String fist = "石頭";
Game(fist);
}
/// <summary>
/// 點擊剪刀按鈕
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnScissors_Click(object sender, EventArgs e)
{
String fist = "剪刀";
Game(fist);
}
/// <summary>
/// 點擊布按鈕
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void btnCloth_Click(object sender, EventArgs e)
{
String fist = "布";
Game(fist);
}
//背景圖片輪播
String[] paths = Directory.GetFiles(@"C:\work\stone");//此目錄裏面必須有圖片，否則會報錯
private void timer1_Tick(object sender, EventArgs e)
{
this.BackgroundImage = Image.FromFile(paths[new Random().Next(0, paths.Length)]);
}
static int playerWinTimes = 0;//玩家贏的次數
static int gameTimes = 0;//總共次數
static int tieTimes = 0;//平手次數
/// <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 = "統計信息：\n\n1.您贏了" + playerWinTimes + "場比賽!\n\n" + "2.平手了" + tieTimes + "次; \n\n" + "3.輸掉了" + (gameTimes - playerWinTimes - tieTimes) + "場比賽; \n\n" + "4.共進行了" + gameTimes + "場比賽!\n\n";
if (result == Judge.RESULT.玩家贏)
{
playerWinTimes++;
MessageBox.Show("恭喜，您已經贏了" + playerWinTimes + "場比賽！" + " 共進行了" + gameTimes + "場比賽！");
}
else if (result == Judge.RESULT.平手)
{
tieTimes++;
}
}
}
}
