Controller--->

barcodecs objbar = new barcodecs();
          for (int i = model.From; i <= model.To; i++)
          {
              Barcode objprod = new Barcode()
              {
                  BookId = model.From,
                  BarCode1 = objbar.generateBarcode(),
                  BarCodeImage = objbar.getBarcodeImage(objbar.generateBarcode(), Convert.ToString(model.BookId)),
              };
              model.From++;
              db.Barcodes.Add(objprod);
              db.SaveChanges();
