I think this blog post will help.

using (Bitmap bitmap = new Bitmap(ParentForm.Size.Width, ParentForm.Size.Height))
{
    using (Graphics g = Graphics.FromImage(bitmap))
    {
      g.CopyFromScreen(new Point(ParentForm.DesktopLocation.X, ParentForm.DesktopLocation.Y), new Point(0, 0), ParentForm.Size);
    }

    bitmap.Save(@"C:\test.jpg", ImageFormat.Jpeg);
}

Never tried it, but i'd think you should be able to call OnPaint(args) with a PaintEventArgs you create, that includes a Graphics for the image you want to draw on, and the ClipRectangle encompassing the whole area of the form.

This would only work if your form properly processes paint messages (ie: if it stores enough info to be able to repaint the window fully at will), and it may only get the client area (ie: it might not get the title bar or menus).
