What is BackgroundWorker?
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.
What is the difference between thread class and background worker in .NET framework?
The BackgroundWorker class is essentially built on top of the Thread class. The RunWorkerCompleted event is what’s triggered when your DoWork event handler finishes up… but the big difference here is that RunWorkerCompleted runs on the thread that started the BackgroundWorker.
What is BackgroundWorker in C# with example?
C# BackgroundWorker component executes code in a separate dedicated secondary thread. We often use background threads when a time-consuming process needed to be executed in the background without affecting the responsiveness of the user interface. This is where a BackgroundWorker component comes into play.
Does BackgroundWorker use ThreadPool?
As such, BackgroundWorker provides no feature that’s useful in a service. Without the custom synchronization provider, the default provider simply runs events on a threadpool thread.
When to use background worker instead of parallel?
The example covers result values, error conditions, cancellation, and progress reporting. Background worker is still a valid way of achieving this – if you are running multiple large operations concurrently then the parallel extensions would be worth considering, if its just the one then I would stick with the backgroundworker.
Which is better the task class or the backgroundworker?
The Task class is an improvement over the BackgroundWorker; it naturally supports nesting (parent/child tasks), uses the new cancellation API, task continuations, etc. I have an example on my blog, showing the old BackgroundWorker way of doing things and the new Task way of doing things.
What’s the difference between backgroundworker and UI code?
Both of them will marshal our MessageBox.Show back to the UI thread, so we don’t have to worry about it. The BackgroundWorker code does suffer from more “ceremony”, since it has to deal with events. It’s also a bit awkward in that you have to wire up your events first and then explicitly start the work going.
Is the background worker still a valid way to achieve this?
Background worker is still a valid way of achieving this – if you are running multiple large operations concurrently then the parallel extensions would be worth considering, if its just the one then I would stick with the backgroundworker.
