Tutorial to Batch Read Barcodes to CSV using ByteScout Barcode Reader SDK

In this tutorial, we will read Barcodes in CSV format. Let’s copy the sample code and paste it into the Visual Studio editor. I added the sample code link in the description box below. To read barcodes, we will use the ‘ByteScout Barcode Reader SDK’. You can add a reference to the Barcode Reader SDK DLL and the Solution Explorer. Right-click on reference and select Add reference. Look at the ‘ByteScout Barcode Reader SDK’ and add. Then add your registration name and registration key and their related properties accordingly. You can get your license details in the ByteScout dashboard. Next set the ‘BarcodeTypesToFind.All = true’.

After that, let’s copy the sample files into our folder. Then we will add our sample file in the solution explorer and set the copy to the output directory to ‘copy always’. We will now load our sample files to our system directory. Our output will be in CSV format. Our CSV output will get and read the barcode value, barcode type, scan date, time and file name.

Now let’s run the program. Our program found eight bar codes in three files. Here are the sample barcodes that we use and here’s the output.
