Winform窗口去边框实现可以移动_winform窗体边框取消后拖拽

Windows自带的边框很影响我们个性化定制窗口UI的美观程序。
首选选择窗口，属性里的FormBorderStyle设置为None。
边框去掉之后 会发现窗口无法最大最小化和移动。
1 在标题栏处新建三个panel，分别为标题栏，最大最小化按钮和关闭按钮

将后面几个panel设置BackgroundImage为相应图标
分别为panel_title panel_min panel_close
为panel_title添加MouseDown和MouseMove事件代码为

private Point mousePoint = new Point();
private void panel_title_MouseDown(object sender, MouseEventArgs e)
        {
            base.OnMouseDown(e);
            this.mousePoint.X = e.X;
            this.mousePoint.Y = e.Y;
        }

        {
            base.OnMouseMove(e);
            if (e.Button == MouseButtons.Left)
            {
                this.Top = Control.MousePosition.Y - mousePoint.Y;
                this.Left = Control.MousePosition.X - mousePoint.X;
            }
        }
