You can try using BarcodeReader class from LEADTOOLS to read one or more barcodes from an image. For example, the following code reads all barcodes in an image: +------------------------+ using(RasterImage image = codecs.Load(imageFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, 1)) { // Read all the barcodes in this image BarcodeData[] barcodes = reader.ReadBarcodes(image, LogicalRectangle.Empty, 0, null); // Print out the barcodes we found Console.WriteLine("{0} contains {1} barcodes", imageFileName, barcodes.Length); for(int i = 0; i { BarcodeData barcode = barcodes[i]; Console.WriteLine(" {0} - {1} - {2}", i + 1, barcode.Symbology, barcode.Value); } Console.WriteLine("-----------------"); } +------------------------+ You can use the above code in your ASP.NET server side code, or in a web-service. You can find more details in the following online links: https://www.leadtools.com/help/leadtools/v19m/dh/ba/barcodereader.html Also, check the following online barcode demo: http://demo.leadtools.com/JavaScript/Barcode/index.html
