public BarcodeData( 
   BarcodeSymbology symbology,
   string value
)

'Declaration
 
Public Function New( _
   ByVal symbology As BarcodeSymbology, _
   ByVal value As String _
)

'Usage
 
Dim symbology As BarcodeSymbology
Dim value As String
 
Dim instance As New BarcodeData(symbology, value)

public BarcodeData( 
   BarcodeSymbology symbology,
   string value
)

ObjectiveC Syntax

Java Syntax

function BarcodeData( 
   symbology ,
   value 
)

public:
BarcodeData( 
   BarcodeSymbology symbology,
   String^ value
)

Parameters

symbology: Barcode symbology to use.
value: A System.String that specifies the ASCII text representation of the barcode data.

This constructor initializes the BarcodeData member as follows:

s

Member	Value
Symbology	symbology
Bounds	LogicalRectangle.Empty
RotationAngle	0
Byte array inside GetData	The raw value of the bytes array in value. if this parameter is null, then the data is null too.
Value	value.
Tag	null (Nothing in Visual Basic)

To quickly construct a new BarcodeData object with a specific symbology and data as a raw byte array, use BarcodeData(BarcodeSymbology symbology, byte[] data) to construct a default BarcodeData, use BarcodeData().

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