C# 画面手动随意移动代码


点击form画面，按下鼠标后，随意迁移画面代码：

        private void Form1_MouseDown(object sender, MouseEventArgs e)

        {

            mouse_offset = new Point(-e.X, -e.Y);

        }

        private void Form1_MouseMove(object sender, MouseEventArgs e)

        {

            if (e.Button == MouseButtons.Left)

            {

                Point mousePos = Control.MousePosition;

                mousePos.Offset(mouse_offset.X, mouse_offset.Y);

                Location = mousePos;

            }

        } 

       

MouseDown和MouseMove事件，在form上追加。
