回答1:

Use the ReportProgress method in combination with the ProgressChanged event. This type of scenario is exactly what they are intended for.

You can use ReportProgress method of background worker.

You would need to implement a foreground worker and invoke it from the background worker.

Ideally, you would be passing a list of any newly found files to the foreground worker.
