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

    barCode.Options.QRCode.ErrorLevel = QRCodeErrorLevel.Q;
    barCode.Options.QRCode.ShowCodeText = false;
    barCode.DpiX = 72;
