[SerializableAttribute()] public enum class BarcodeReadSymbologyOperation : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable
| Value | Member | Description |
|---|---|---|
| 0 | PreRead |
The BarcodeReader object is about to read the barcode symbologies. The input parameters are: The symbologies to be read which can be obtained through the GetSymbologies method and the associated read options that are in the Options property. |
| 1 | PostRead |
The BarcodeReader has finished reading the barcode symbologies. The input parameters are: The symbologies to be read which can be obtained through the GetSymbologies method and the associated read options that are in the Options property. The resulting parameters are: The barcode data found which is in the Data property that may contain a valid BarcodeData object or null (Nothing in Visual Basic) when an error occurs or no barcode of this type is found. In case of an error, the exception is in the Error property (Refer to BarcodeReader.ErrorMode for more information). |
This enumeration is used as the type for the BarcodeReadSymbologyEventArgs.Operation property that can be used to determine the current barcode read stage.
For an example, refer to BarcodeReader.ReadSymbology.
