C#中如何实现拖动PictureBox控件

思路是这样的.得有三个变量. 记录x坐标: int xPos; 记录y坐标: int yPos; 记录是否按下鼠标: bool MoveFlag;

//在picturebox的鼠标按下事件里,记录三个变量. private void picBox_MouseDown(object sender, MouseEventArgs e) {     MoveFlag = true;//已经按下.     xPos = e.X;//当前x坐标.     yPos = e.Y;//当前y坐标. }

//在picturebox的鼠标按下事件里. private void picBox_MouseUp(object sender, MouseEventArgs e) {     MoveFlag = false; }

//在picturebox鼠标移动 private void picBox_MouseMove(object sender, MouseEventArgs e) {     if (MoveFlag)     {         picBox.Left += Convert.ToInt16(e.X - xPos);//设置x坐标.         picBox.Top += Convert.ToInt16(e.Y - yPos);//设置y坐标.     } }

这样就可以实现控件在容器里的移动
