  protected override void Dispose(bool disposing)

   if (disposing)
   {
    this.DisposeGraphics();
   }

 }
}

調用：
  private void button1_Click(object sender, System.EventArgs e)
  {
   int width = 400;
   int height = 400;
   m_Bitmap = new Bitmap(width, height);
   g = Graphics.FromImage(m_Bitmap);
   g.Clear(Color.White);
   PartyLogoA partyLogoA = new PartyLogoA();
   partyLogoA.Width = width;
   partyLogoA.Height = height;
   partyLogoA.Color = Color.Red;
   partyLogoA.RenderGraphics(g);
   this.Invalidate();
  }
