public BarcodeData( 
   BarcodeSymbology symbology,
   byte[] data
)

'Declaration
 
Public Function New( _
   ByVal symbology As BarcodeSymbology, _
   ByVal data() As Byte _
)

'Usage
 
Dim symbology As BarcodeSymbology
Dim data() As Byte
 
Dim instance As New BarcodeData(symbology, data)

public BarcodeData( 
   BarcodeSymbology symbology,
   byte[] data
)

ObjectiveC Syntax

Java Syntax

function BarcodeData( 
   symbology ,
   data 
)

public:
BarcodeData( 
   BarcodeSymbology symbology,
   array<byte>^ data
)

Parameters

symbology: Barcode symbology to use.
data: An array of System.Byte that specifies the data to use. This value can be null (Nothing in Visual Basic).

This constructor initializes the BarcodeData member as follows:

Member	Value
Symbology	symbology
Bounds	LogicalRectangle.Empty
RotationAngle	0
Byte array inside GetData	data (same reference, the data is not copied)
Value	ASCII text string representation of data, if this parameter is null, then Value is null too.
Tag	null (Nothing in Visual Basic)

To quickly construct a new BarcodeData object with a specific symbology and data as a string value, use BarcodeData(BarcodeSymbology symbology, string value) to construct a default BarcodeData, use BarcodeData().

To create an instance of BarcodeData suitable for writing for a specified symbology, use CreateDefaultBarcodeData.
