2、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
}
}



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)
{
}

}
}



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）

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

namespace 拼图
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private Puzzle puzzle;
private int Num=0;
private Image img;
private void Form1_Load(object sender, EventArgs e)
{
img = GamePage.img;
pictureBox2.Image = img.GetThumbnailImage(120,120, new Image.GetThumbnailImageAbort(delegate { return false; }), IntPtr.Zero);
puzzle = new Puzzle(img, 600, GamePage.Dif);
pictureBox1.Image =puzzle.Display();
}

private void pictureBox1_MouseClick(object sender, MouseEventArgs e)
{
if (puzzle.Move(e.X / (puzzle.Width / puzzle.N), e.Y / (puzzle.Width / puzzle.N)))
{
Num++;
pictureBox1.Image = puzzle.Display();
if (puzzle.Judge())
{
if (MessageBox.Show("恭喜过关", "是否重新玩一把", MessageBoxButtons.OKCancel) == DialogResult.OK)
{
Num = 0;
puzzle.Upset();
pictureBox1.Image = puzzle.Display();

}
else
{
Num = 0;
closefather();
this.Close();
}

}

}
NumLabel.Text = Num.ToString();
}

private void pictureBox2_MouseEnter(object sender, EventArgs e)
{
pictureBox1.Image = img;
}

private void pictureBox2_MouseLeave(object sender, EventArgs e)
{
pictureBox1.Image = puzzle.Display();
}

private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
closefather();
}
public delegate void childclose();
public event childclose closefather;

}
}
