public: property Exception^ Error { Exception^ get(); }
If an error occurs during the read operation and Error contains a valid exception object, then depending on the value of BarcodeReader.ErrorMode, the BarcodeReader object may throw this exception after the event handler returns. This is determined as follows:
Value | Action |
---|---|
BarcodeReaderErrorMode.Default |
(Default behavior). The BarcodeReader will throw the error after the event handler returns. You must catch this exception in your application. |
BarcodeReaderErrorMode.IgnoreAll |
The System.Exception object is still in Error, but the BarcodeReader will not throw the exception when the event handler returns. It is up to you to decide if and when to throw the exception and how to handle it. The C# and VB Barcode Main Demo shows the errors (if any) in a list after the read operation is completed. |
For an example, refer to BarcodeReader.ReadSymbology.
