Reading Barcodes

The BarcodeReader.ReadBarcode or BarcodeReader.ReadBarcodes methods are used to read a barcode or more from an image. Each of these methods return an object or an array of objects of type BarcodeData for each barcode found. Inside each object, the value of the Symbology property will be set by the BarcodeReader object to the symbology (or type) of the barcode. You can examine this value to decide how to parse the data of the barcode stored in GetData or Value.

The value of Symbology will never be BarcodeSymbology.Unknown on BarcodeData objects returned from BarcodeReader.ReadBarcode or BarcodeReader.ReadBarcodes.
