C#创建可以随意拖动的控件,拖动窗体上的任意控件到指定位置

主要代码如下:

Point mouse_offset = new Point();

public MyPicture()
        {
            this.MouseMove += new MouseEventHandler(Common_MouseMove);
            this.MouseDown += new MouseEventHandler(Common_MouseDown);
        }

        private void Common_MouseMove(object sender, MouseEventArgs e)
        {
            Control control = (Control)sender;
            //((Control)sender).Cursor = Cursors.Arrow;
            if (e.Button == MouseButtons.Left)
            {
                //Point mousePos = Control.MousePosition;
                //mousePos.Offset(mouse_offset.X, mouse_offset.Y);
                //((Control)sender).Location = ((Control)sender).Parent.PointToClient(mousePos);
               
                    control.Left = control.Left + e.X - mouse_offset.X;
                    control.Top = control.Top + e.Y - mouse_offset.Y;
              
            }
        }
        private void Common_MouseDown(object sender, MouseEventArgs e)
        {
            mouse_offset = new Point(e.X, e.Y);
        }
我用的就是这段代码.
