1.构造函数：传图片并分割成一个一个小图片
2.交换方法
3.大图中截取小单元方法
4.移动单元的方法
5.打乱单元顺序方法

配置类：
using System; using System.Collections.Generic; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; namespace 拼图 { public static class GamePage { public static Puzzle.Diff Dif; //游戏难度 public static Image img; //拼图图案 } }
游戏菜单：
通过菜单，上传图片至配置类img，并选择难度上传至配置类Dif，然后拼图对象构造时读取配置类
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace 拼图 { public partial class Menu : Form { public Menu() { InitializeComponent(); GamePage.img =Image.FromFile(@"Image\\拼图.jpg"); Control.CheckForIllegalCrossThreadCalls = false; } private void button1_Click(object sender, EventArgs e) { GamePage.Dif = Puzzle.Diff.simple; this.Hide(); Form1 ff = new Form1(); ff.closefather+=new 拼图.Form1.childclose(this.closethis); ff.Show(); } private void button2_Click(object sender, EventArgs e) { GamePage.Dif = Puzzle.Diff.ordinary; this.Hide(); Form1 ff = new Form1(); ff.closefather += new 拼图.Form1.childclose(this.closethis); ff.Show(); } private void button3_Click(object sender, EventArgs e) { GamePage.Dif = Puzzle.Diff.difficulty; this.Hide(); Form1 ff = new Form1(); ff.closefather += new 拼图.Form1.childclose(this.closethis); ff.Show(); } public void closethis() { this.Show(); } private void button4_Click(object sender, EventArgs e) { OpenFileDialog ofd = new OpenFileDialog(); ofd.ShowDialog(); GamePage.img = Image.FromFile(ofd.FileName).GetThumbnailImage(600,600,new Image.GetThumbnailImageAbort(delegate { return false; }), IntPtr.Zero); } private void Menu_Load(object sender, EventArgs e) { } } }
游戏运行窗口：
1.注册鼠标点击事件来获得输入消息
2.显示功能
3.pictureBox1用来展示游戏拼图情况
4.pictureBox2展示完整拼图的缩略图（当鼠标移至pictureBox2时，发送消息，使pictureBox1显示完整拼图）
5.Numlabel来显示移动步数（通过变量Num的累加来计算）
