	  {
            GenerateBarcodes("Product Code", "Product Name", "Product Price");
          }

          public static void GenerateBarcodes(string productCode, string productName, string productPrice)
          {
            Font stringFornt = new Font("Arial", 15, FontStyle.Bold, GraphicsUnit.Point);
            Font barcodeFont = new Font("Free 3 of 9", 40, FontStyle.Regular, GraphicsUnit.Point);
            Bitmap barcodeImage = new Bitmap(140, 110);
            Graphics graph = Graphics.FromImage(barcodeImage);

            graph = Graphics.FromImage(barcodeImage);
            graph.Clear(Color.White);
            graph.TextRenderingHint = TextRenderingHint.SingleBitPerPixel;
            graph.DrawString(productName, stringFornt, new SolidBrush(Color.Black), 10, 0);
            graph.DrawString(productCode, barcodeFont, new SolidBrush(Color.Black), 0, 30);
            graph.DrawString(productCode, stringFornt, new SolidBrush(Color.Black), 10, 70);
            graph.DrawString(productPrice, stringFornt, new SolidBrush(Color.Black), 10, 90);
            graph.Flush();

            barcodeImage.Save(@"D:\barcode.jpg", ImageFormat.Jpeg);
