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;

}
}
private void PictureBox_DragEnter(object sender, DragEventArgs e)
{

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