当form的formBorderStyle设置为None时，如何实现窗体拖动

[blueteeth_yl]

就是自己重新弄一个标题栏的东西，然后实现拖动

没这么做过，看看高手怎么处理的

        private Point mouseOffset;        //记录鼠标指针的坐标
        private bool isMouseDown = false; //记录鼠标按键是否按下

        private void picCLose_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }

        private void fmLogin_MouseDown(object sender, MouseEventArgs e)
        {
            int xOffset;
            int yOffset;

            if (e.Button == MouseButtons.Left)
            {
                xOffset = -e.X - SystemInformation.FrameBorderSize.Width;
                yOffset = -e.Y - SystemInformation.CaptionHeight -
                 SystemInformation.FrameBorderSize.Height;
                mouseOffset = new Point(xOffset, yOffset);
                isMouseDown = true;
            }
        }

        private void fmLogin_MouseMove(object sender, MouseEventArgs e)
        {
            if (isMouseDown)
            {
                Point mousePos = Control.MousePosition;
                mousePos.Offset(mouseOffset.X+5, mouseOffset.Y+30);
                Location = mousePos;
            }
        }

        private void fmLogin_MouseUp(object sender, MouseEventArgs e)
        {
            // 修改鼠标状态isMouseDown的值
            // 确保只有鼠标左键按下并移动时，才移动窗体
            if (e.Button == MouseButtons.Left)
            {
                isMouseDown = false;
            }
        }

在窗体的mousedown事件中实现拖动。

//拖动窗体

ReleaseCapture();
SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
