 QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(code,QRCodeGenerator.ECCLevel.Q);
 System.Web.UI.WebControls.Image imgBarCode = new System.Web.UI.WebControls.Image();
 imgBarCode.Height = 150;
 imgBarCode.Width = 150;
 using (Bitmap bitMap = qrCode.GetGraphic(20))
  {
    using (MemoryStream ms = new MemoryStream())
    {
      bitMap.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
