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<PictureBox, Point> originalPositions = new Dictionary<PictureBox, Point>();//初始位置
        private Dictionary<PictureBox, Point> currentPositions = new Dictionary<PictureBox, Point>();//当前位置

用picturebox存放拼图

用Dictionary<PictureBox, Point>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;

}

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。
