Thanks for this article. I have a question. I would like to pass a function that takes in parameter, but in the argument line it doesn’t allow you to pass parameter as it is a Action of T Implementation. I need my argument to be readily available so when the worker get to my item function it knows the object. How would i do that?

Hi,

Good article, I tried to reproduce this with ReportProgress too, but getting cross-thread exception (InvalidOperationException), can you update with a ReportProgress option too please?

Thanks,
Nanda

[...] What I found was an unbelievably perfect solution from Matt Valerio with his post titled "A Queued BackgroundWorker Using Generic Delegates". As the title suggests, he wrote a class called “QueuedBackgroundWorker” that would add [...]

Hi Matt,
THanks for the posting. I find it very useful in my project. However, I am wondering if turning the SupportsCancellation flag on would stop the background worker. I noticed that the cancelAsync is not implemented in this sample. THe scenario is that I need to cancel the background worker when I close my winform ( while the background worker still performing a task). Please advice.

Thanks

Regards,
Balan Sinniah

Matt, thanks for providing this example.

This solution is exactly what I needed for the application I’m writing. Your code required reading MSDN on my part, because I didn’t understand lambda and parameter typing, but it forced me to learn.

Thanks.

Hi Matt. a colleague of mine and I were discussing the code sample you posted, and we were both wondering about your reasoning behind the design of this solution. Why are you queing up individual background threads, instead of sending the data you want processed synchronously to one background thread? Wouldn’t queing up additional threads create a lot of unnecesary overhead?

Thanks!

Awesome piece of code! I haven’t played around with even the new .NET 3.0 features yet but it looks like there’s some great new additions.

Cheers!
