winfrom 中boderstyle 設置爲none後不能移動的問題

 bool formMove = false;//窗體是否移動
        Point formPoint;//記錄窗體的位置
        private void Form1_MouseDown(object sender, MouseEventArgs e)
        {
            formPoint = new Point();
            int xOffset;
            int yOffset;
            if (e.Button == MouseButtons.Left)
            {
                xOffset = -e.X - SystemInformation.FrameBorderSize.Width;
                yOffset = -e.Y - SystemInformation.CaptionHeight - SystemInformation.FrameBorderSize.Height;
                formPoint = new Point(xOffset, yOffset);
                formMove = true;//開始移動
            }
        }


        private void Form1_MouseUp(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)//按下的是鼠標左鍵
            {
                formMove = false;//停止移動
            }
        }


        private void Form1_MouseMove(object sender, MouseEventArgs e)
        {
            if (formMove == true)
            {
                Point mousePos = System.Windows.Forms.Control.MousePosition;
                mousePos.Offset(formPoint.X, formPoint.Y);
                Location = mousePos;
            }
        }

醬紫就可以了,Mark一下!
