Jan 07, 2011 · If you are using the BackgroundWorker in your app and you’ve set it up to support cancellation, be careful how you write your code that watches for cancellation. BackgroundWorker has an event DoWork, which passes DoWorkEventArgs. This derives from CancelEventArgs, which has a property named Cancel. The unsuspecting developer (like me) might assume that e.Cancel is the property to check for detecting if the work has been cancelled…

One of the biggest drawbacks to cancellation support in BackgroundWorker is that it’s just plain convoluted. Even when I was using BackgroundWorker regularly, every time I had to support cancellation, I had to look up how to do it. It’s just too complex to remember easily.

Sep 08, 2008 · Ofcourse during looping I switch the timer off, so I don't run into troubles. But when I close the application I call also the CancelAsync(), so to cancel the backgroundworker, but than I get an exception about a thread is still running. Do you know how I can close the backgroundworker and the serial port on gentle way, while DoWork is looping?4.9/5(113)

The problem is this when you cancel the background worker the thread does not imediately cancel, so you can not cancel and imediatley restart the background worker, this may or may not work. My original suggestion was only for code inside of the DoWork routine, you would still need to decide if the BackgroundWorker was busy before trying to start it.

Nov 02, 2011 · JohnWein, I'm absolutely positive that the backgroundworker is not cancelled. It does it every time. It seems that a _DoWork routine can not cancel it's own background worker. You've got something else going on.

Caution. Be aware that your code in the DoWork event handler may finish its work as a cancellation request is being made, and your polling loop may miss CancellationPending being set to true.In this case, the Cancelled flag of System.ComponentModel.RunWorkerCompletedEventArgs in your RunWorkerCompleted event handler will not be set to true, even though a cancellation request was …
