        private static extern IntPtr GetWindowDC(IntPtr hWnd);
        [DllImport("user32.dll")]
        private static extern int ReleaseDC(IntPtr hWnd, IntPtr hDC);        private const int WM_NCPAINT = 0x0085;
        private const int WM_NCACTIVATE = 0x0086;
        private const int WM_NCLBUTTONDOWN = 0x00A1;
        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
            Rectangle vRectangle = new Rectangle((Width - 75) / 2, 3, 75, 25);
            switch (m.Msg)
            {
                case WM_NCPAINT:
                case WM_NCACTIVATE:
                    IntPtr vHandle = GetWindowDC(m.HWnd);
                    Graphics vGraphics = Graphics.FromHdc(vHandle);
                    vGraphics.FillRectangle(new LinearGradientBrush(vRectangle,
                        Color.Pink, Color.Purple, LinearGradientMode.BackwardDiagonal),
                        vRectangle);                    StringFormat vStringFormat = new StringFormat();
                    vStringFormat.Alignment = StringAlignment.Center;
                    vStringFormat.LineAlignment = StringAlignment.Center;
                    vGraphics.DrawString("About", Font, Brushes.BlanchedAlmond,
                        vRectangle, vStringFormat);                    vGraphics.Dispose();
                    ReleaseDC(m.HWnd, vHandle);
                    break;
                case WM_NCLBUTTONDOWN:
                    Point vPoint = new Point((int)m.LParam);
                    vPoint.Offset(-Left, -Top);
                    if (vRectangle.Contains(vPoint))
                        MessageBox.Show(vPoint.ToString());
                    break;

重写WndProc、在绘制窗口的时候在顶层再画一个按钮、后面是根据拿到已经画好按钮的坐标、在坐标内触发click事件
这方法不是挺好的么，就用这个
