barCode.BackColor = Color.White;
barCode.ForeColor = Color.Black;
barCode.RotationAngle = 0;
barCode.CodeBinaryData = Encoding.Default.GetBytes(barCode.CodeText);

barCode.Options.QRCode.ShowCodeText = false;

using (FileStream stream = new FileStream("BarCodeImage.png", FileMode.Create))
{
    barCode.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
