Senerio

We have a C# .Net Web Application that records incidents. An external database needs to be queried when an incident is approved by a supervisor. The queries to this external database are sometimes taking a while to run. This lag is experienced through the browser.

Possible Solution

I want to use threading to eliminate the simulated hang to the browser. I have used the Thread class before and heard about ThreadPool. But, I just found BackgroundWorker in this post.

MSDN states:

The BackgroundWorker class allows you to run an operation on a separate, dedicated thread. Time-consuming operations like downloads and database transactions can cause your user interface (UI) to seem as though it has stopped responding while they are running. When you want a responsive UI and you are faced with long delays associated with such operations, the BackgroundWorker class provides a convenient solution.

Is BackgroundWorker the way to go when handling long running queries?

What happens when 2 or more BackgroundWorker processes are ran simultaneously? Is it handled like a pool?

    Yes, BackgroundWorker can significantly simplify your threading code for long-running operations. The key is registering for the DoWork, ProgressChanged, and RunWorkerCompleted events. These help you avoid having to have a bunch of synchronization objects passed back and forth with the thread to try to determine the progress of the operation.

    Also, I believe the progress events are called on the UI thread, avoiding the need for calls to Control.Invoke to update your UI.

    To answer your last question, yes, threads are allocated from the .NET thread pool, so you while you may instantiate as many BackgroundWorker objects as you’d like, you can only run as many concurrent operations as the thread pool will allow.
