public static void Save( string fileName, BarcodeData[] data )
ObjectiveC Syntax
public: static void Save( String^ fileName, array<BarcodeData^>^ data )
The load/save methods are provided as helper methods for the user. The BarcodeEngine, BarcodeReader and BarcodeWriter do not use these methods internally.
data can be null (Nothing is Visual Basic). This is the equivalent of saving an empty array.
To load the data previously saved into an XML file, use BarcodeData.Load(string fileName).
To save and load data to an XML stream, use BarcodeData.Save(Stream stream, BarcodeData[] data) and BarcodeData.Load(Stream stream).
