نحوه اسال یه کامپوننت و براش در c#

سلام - چون اون چیزی که در عنوان سوال مطرح کردم رو بلد نیستم - تابع مورد نیاز رو به صورت زیر نوشتم - اگه میشد به تابع نام panel رو رسال کنم و رنگ براش - اون وقت تابع خیلی ساده میشد - کسی نحوه این کار رو میدونه؟

 private void SetFillEllipse(bool Color, int Pannel) {
Graphics g = CreateGraphics();
if (Color)
{
if (Pannel == 1) g.FillEllipse(Brushes.Green, panel1.Location.X/*x*/, panel1.Location.Y/*y*/, panel1.Width/*width*/, panel1.Height/*height*/);
if (Pannel == 2) g.FillEllipse(Brushes.Green, panel2.Location.X/*x*/, panel2.Location.Y/*y*/, panel2.Width/*width*/, panel2.Height/*height*/);
if (Pannel == 3) g.FillEllipse(Brushes.Green, panel3.Location.X/*x*/, panel3.Location.Y/*y*/, panel3.Width/*width*/, panel3.Height/*height*/);
if (Pannel == 4) g.FillEllipse(Brushes.Green, panel4.Location.X/*x*/, panel4.Location.Y/*y*/, panel4.Width/*width*/, panel4.Height/*height*/);
if (Pannel == 5) g.FillEllipse(Brushes.Green, panel5.Location.X/*x*/, panel5.Location.Y/*y*/, panel5.Width/*width*/, panel5.Height/*height*/);
if (Pannel == 6) g.FillEllipse(Brushes.Green, panel6.Location.X/*x*/, panel6.Location.Y/*y*/, panel6.Width/*width*/, panel6.Height/*height*/);
if (Pannel == 7) g.FillEllipse(Brushes.Green, panel7.Location.X/*x*/, panel7.Location.Y/*y*/, panel7.Width/*width*/, panel7.Height/*height*/);
if (Pannel == 8) g.FillEllipse(Brushes.Green, panel8.Location.X/*x*/, panel8.Location.Y/*y*/, panel8.Width/*width*/, panel8.Height/*height*/);
}
else
{
if (Pannel == 1) g.FillEllipse(Brushes.Red, panel1.Location.X/*x*/, panel1.Location.Y/*y*/, panel1.Width/*width*/, panel1.Height/*height*/);
if (Pannel == 2) g.FillEllipse(Brushes.Red, panel2.Location.X/*x*/, panel2.Location.Y/*y*/, panel2.Width/*width*/, panel2.Height/*height*/);
if (Pannel == 3) g.FillEllipse(Brushes.Red, panel3.Location.X/*x*/, panel3.Location.Y/*y*/, panel3.Width/*width*/, panel3.Height/*height*/);
if (Pannel == 4) g.FillEllipse(Brushes.Red, panel4.Location.X/*x*/, panel4.Location.Y/*y*/, panel4.Width/*width*/, panel4.Height/*height*/);
if (Pannel == 5) g.FillEllipse(Brushes.Red, panel5.Location.X/*x*/, panel5.Location.Y/*y*/, panel5.Width/*width*/, panel5.Height/*height*/);
if (Pannel == 6) g.FillEllipse(Brushes.Red, panel6.Location.X/*x*/, panel6.Location.Y/*y*/, panel6.Width/*width*/, panel6.Height/*height*/);
if (Pannel == 7) g.FillEllipse(Brushes.Red, panel7.Location.X/*x*/, panel7.Location.Y/*y*/, panel7.Width/*width*/, panel7.Height/*height*/);
if (Pannel == 8) g.FillEllipse(Brushes.Red, panel8.Location.X/*x*/, panel8.Location.Y/*y*/, panel8.Width/*width*/, panel8.Height/*height*/);
}
