Reading GS1-128 / EAN-128 in C# Class

Here we have generated a sample GS1-128 barcode image with GS1 data "(01)09012345678901(17)240915(10)abc123(3930)978112".

Use the following C# source code, you could easily read all GS1 data elements from the above GS1-128 barcode image.

  • Choose target barcode type as BarcodeType.Code128. GS1-128 data is using Code 128 barcode as data carrier.

  • Call method BarcodeScanner.ScanInDetails() to read, scan a barcode image file with the target barcode type.

  • For all the returned all scanned BarcodeDetail objects, check each barcode is a GS1 barcode using method IsGS1Compitable().

  • Get the GS1 data message using BarcodeDetail.GetMessage().

            string inputFilePath = "W://Projects//Test-Input//gs1-sample-data-gs1-128.png";
            //  Scan barcodes from the input image file.
            BarcodeDetail[] result = BarcodeScanner.ScanInDetails(inputFilePath, BarcodeType.Code128);
            foreach (BarcodeDetail b in result)
                //  Indicate if the barcode is conform to GS1 specification.
                if (b.IsGS1Compitable)
                    //  Get message in string format.
                    //  Eg. "(415)5412345678908(3911)710125"
                    String msg = b.GetMessage();
                    Console.WriteLine("Data: '{0}'", b.Data);
                    Console.WriteLine("Message: {0}", msg);
                    //  Retrieve each AI and its data from the message.
                    //  Eg.
                    //  AI:   415
                    //  Data: 5412345678908
                    //  AI:   3911
                    //  Data: 710125
                    String[] vals = msg.Split(new char[] { '(', ')' }, StringSplitOptions.RemoveEmptyEntries);
                    for (int i = 0; i < vals.Length; i += 2)
                        Console.WriteLine("AI:    {0}", vals[i]);
                        Console.WriteLine("Data:  {0}", vals[i + 1]);

Output in the console window:

Data: '01090123456789011724091510abc1233930978112'
Message: (01)09012345678901(17)240915(10)abc123(3930)978112
AI:    01
Data:  09012345678901
