public static void Save( 
   string fileName,
   BarcodeData[] data
)

'Declaration
 
Public Overloads Shared Sub Save( _
   ByVal fileName As String, _
   ByVal data() As BarcodeData _
)

'Usage
 
Dim fileName As String
Dim data() As BarcodeData
 
BarcodeData.Save(fileName, data)

public static void Save( 
   string fileName,
   BarcodeData[] data
)

ObjectiveC Syntax

 function Leadtools.Barcode.BarcodeData.Save(String,BarcodeData[])( 
   fileName ,
   data 
)

public:
static void Save( 
   String^ fileName,
   array<BarcodeData^>^ data
)

Parameters

fileName: Name of the XML file to create
data: An array of BarcodeData objects to save.

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).
