 /// <summary>
        /// 最大化、正常
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void buttonSize_Click(object sender, EventArgs e)
        {
             if (this.WindowState == FormWindowState.Maximized)
            {
                this.WindowState = FormWindowState.Normal;
                Size = new Size(1024, 728);
                this.StartPosition = FormStartPosition.CenterScreen;
            }
            else
            {
               this.WindowState = FormWindowState.Maximized;
            }

是这样的 因为无边框的窗体嘛 在窗体的右下角会有个 三条虚线 鼠标按下后可以调整窗体大小
但是因为设计原因 这个部分被panel遮盖住了 就替换个图片的 三条虚线 来实现窗体大小的调整
现状不知道该怎么做

你可以试试用button_click()事件做一下……
