public: 
array<BarcodeReadOptions^>^ GetAllDefaultOptions();  

Return Value

An array of BarcodeReadOptions derived types that contain all the default read options currently set in this BarcodeReader.

Remarks

The BarcodeReader object contains an array of all the default read options used by the ReadBarcode and ReadBarcodes methods when no explicit options are passed by the user.
