Support and trial license email: nuget@bardecode.com

Basic use:

barcode = new SoftekBarcodeNet.BarcodeReader(); nBarCode = barcode.ScanBarCode("inputfile.pdf"); // Can be TIF, BMP, JPG or PDF for (int i = 1; i ⇐ nBarCode; i++) value = barcode.GetBarString(i);

Setting more options and getting more results:
