Syntax

C#
VB
C++
public void Save( 
   string fileName 
) 
Public Overloads Sub Save( _ 
   ByVal fileName As String _ 
)  
public: 
void Save(  
   String^ fileName 
)  

Parameters

fileName
Name of the XML file to create

Remarks

The load/save methods are provided as helper methods for the user. The BarcodeEngine, BarcodeReader and BarcodeWriter do not use these methods internally.

To load the data previously saved into an XML file, use BarcodeReadOptions.Load(string fileName).

To save and load data to an XML stream, use BarcodeReadOptions.Save(Stream stream) and BarcodeReadOptions.Load(Stream stream).

To save the default read options used by BarcodeReader, use BarcodeReader.SaveOptions

Example

This example creates Linear 1D barcode read options class, saves it to the disk and then loads it back.
