2.实现

2.1 分割并打乱图片

创建 c# winform 项目 pintu_game

        private const int CellSize = 100;//每块拼图的大小
        private PictureBox[,] pictureBoxes = new PictureBox[3, 3];//创建3x3个picturebox
        private Dictionary originalPositions = new Dictionary();//初始位置
        private Dictionary currentPositions = new Dictionary();//当前位置

用picturebox存放拼图

用Dictionary存放数据

只要比较 originalPositions和currentPositions就能判断胜利

        private bool IsPuzzleSolved()
        {
            foreach (var entry in currentPositions)
            {
                PictureBox pb = entry.Key;
                Point currentPos = entry.Value;
                Point originalPos = originalPositions[pb];

                if (currentPos.X != originalPos.X || currentPos.Y != originalPos.Y)
                {
                    return false;
                }
            }
            return true;
        }

entry.Key 表示字典中的键(Key),对应拼图块的控件对象

entry.Value 表示字典中的值(Value),对应拼图块的坐标(Point 类型,包含 X 和 Y 属性)。

调整原图尺寸:

        private Image resize_img(Image originalImage)
        {
            //调整原图的尺寸为300x300
            Bitmap resizedImage = new Bitmap(300, 300);
            using (Graphics g = Graphics.FromImage(resizedImage))
            {
                g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
                g.DrawImage(originalImage, 0, 0, 300, 300);
            }
            return resizedImage;
        }

  • 新建一个300x300像素的空白位图作为目标画布

  • 通过Graphics.FromImage获取目标位图的绘图对象

  • 指定使用双三次插值法(Bicubic Interpolation)

        分割图片
        private void CutImage()
        {
            for (int i = 0; i < GridSize; i++)
            {
                for (int j = 0; j < GridSize; j++)
                {
                    // 创建每个部分的位图
                    Bitmap part = new Bitmap(CellSize, CellSize);
                    using (Graphics g = Graphics.FromImage(part))
                    {
                        // 计算源图像中的矩形区域
                        Rectangle srcRect = new Rectangle(j * CellSize, i * CellSize, CellSize, CellSize);
                        // 计算目标图像中的矩形区域
                        Rectangle destRect = new Rectangle(0, 0, CellSize, CellSize);
                        // 绘制图像部分
                        g.DrawImage(originalImage, destRect, srcRect, GraphicsUnit.Pixel);
                    }
                    imageParts[i, j] = part;
                }
            }
        }

打乱顺序

            // 收集所有拼图块
            foreach (PictureBox pb in pictureBoxes)
            {
                boxes.Add(pb);
            }

            // 洗牌
            int n = boxes.Count;
            while (n > 1)
            {
                n--;
                int k = rand.Next(n + 1);
                PictureBox temp = boxes[k];
                boxes[k] = boxes[n];
                boxes[n] = temp;

此阶段代码:

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 pintu_game{ public partial class Form1 : Form { private const int CellSize = 100;//每块拼图的大小 static private int GridSize = 3;//拼图数 private PictureBox[,] pictureBoxes = new PictureBox[GridSize, GridSize];//创建3x3个picturebox private Dictionary originalPositions = new Dictionary();//初始位置 private Dictionary currentPositions = new Dictionary();//当前位置 private Image originalImage = Image.FromFile(\"rabbit.png\");//原图 private Image[,] imageParts = new Image[GridSize, GridSize];//分割后的图片 private const int Spacing = 5;//分割图片之间的留白大小 public Form1() { InitializeComponent(); InitializeGame(); } private void InitializeGame() { //调整尺寸 originalImage = resize_img(originalImage); // 切割图片 CutImage(); // 创建游戏面板 CreateGameBoard(); // 打乱拼图 ShufflePuzzle(); } //调整尺寸 private Image resize_img(Image originalImage) { //调整原图的尺寸为300x300 Bitmap resizedImage = new Bitmap(300, 300); using (Graphics g = Graphics.FromImage(resizedImage)) { g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; g.DrawImage(originalImage, 0, 0, 300, 300); } return resizedImage; } //分割图片 private void CutImage() { for (int i = 0; i < GridSize; i++) { for (int j = 0; j  ShufflePuzzle(); Controls.Add(restartButton); // 检查按钮 Button checkButton = new Button { Text = \"检查\", Location = new Point(150, ClientSize.Height - 25), Size = new Size(100, 20) }; Controls.Add(checkButton); // 创建所有拼图块 for (int i = 0; i < GridSize; i++) { for (int j = 0; j < GridSize; j++) {  PictureBox pb = new PictureBox  { Size = new Size(CellSize, CellSize), Location = new Point(Spacing + j * (CellSize + Spacing),  Spacing + i * (CellSize + Spacing)), Image = imageParts[i, j], SizeMode = PictureBoxSizeMode.StretchImage,  };  Controls.Add(pb);  pictureBoxes[i, j] = pb;  originalPositions.Add(pb, new Point(i, j));  currentPositions.Add(pb, new Point(i, j)); } } } private void ShufflePuzzle() { Random rand = new Random(); List boxes = new List(); // 收集所有拼图块 foreach (PictureBox pb in pictureBoxes) { boxes.Add(pb); } // 洗牌 int n = boxes.Count; while (n > 1) { n--; int k = rand.Next(n + 1); PictureBox temp = boxes[k]; boxes[k] = boxes[n]; boxes[n] = temp; } // 重新排列图片和位置 for (int i = 0; i < GridSize; i++) { for (int j = 0; j < GridSize; j++) {  int index = i * GridSize + j;  PictureBox pb = boxes[index];  // 更新物理位置  pb.Location = new Point(Spacing + j * (CellSize + Spacing),  Spacing + i * (CellSize + Spacing));  // 更新位置字典  currentPositions[pb] = new Point(i, j);  pictureBoxes[i, j] = pb; } } } private bool IsPuzzleSolved() { foreach (var entry in currentPositions) { PictureBox pb = entry.Key; Point currentPos = entry.Value; Point originalPos = originalPositions[pb]; if (currentPos.X != originalPos.X || currentPos.Y != originalPos.Y) {  return false; } } return true; } }}

运行后:

2.2 拖与放

 private void PictureBox_MouseDown(object sender, MouseEventArgs e) { if (e.Button == MouseButtons.Left) { var pb = (PictureBox)sender; pb.DoDragDrop(pb, DragDropEffects.Move); } } private void PictureBox_DragEnter(object sender, DragEventArgs e) { if (e.Data.GetDataPresent(typeof(PictureBox))) { e.Effect = DragDropEffects.Move; } } private void PictureBox_DragDrop(object sender, DragEventArgs e) { var targetPb = (PictureBox)sender; var sourcePb = (PictureBox)e.Data.GetData(typeof(PictureBox)); // 交换物理位置 Point tempLoc = targetPb.Location; targetPb.Location = sourcePb.Location; sourcePb.Location = tempLoc; // 交换currentPositions记录 Point tempPos = currentPositions[targetPb]; currentPositions[targetPb] = currentPositions[sourcePb]; currentPositions[sourcePb] = tempPos; // 同步更新pictureBoxes数组 for (int i = 0; i < GridSize; i++) { for (int j = 0; j < GridSize; j++) {  if (pictureBoxes[i, j] == targetPb) pictureBoxes[i, j] = sourcePb;  else if (pictureBoxes[i, j] == sourcePb) pictureBoxes[i, j] = targetPb; } } // 强制刷新界面 targetPb.Refresh(); sourcePb.Refresh(); }

完整拖放流程

  1. 按下鼠标 → MouseDown 启动拖放。
  2. 拖入控件边界 → DragEnter 验证并显示反馈。
  3. 释放鼠标 → DragDrop 执行实际交换操作。
