How does DoWork pass parameters to BackgroundWorker?
You can send a parameter to the background operation using the RunWorkerAsync() method. You can receive this parameter by using the Argument property of the instance of DoWorkEventArgs in the DoWork event handler then you cast it to use it in the background operation.
What is a 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 and BackgroundWorker C#?
BackgroundWorker has already implemented functionality of reporting progress, completion and cancellation – so you don’t need to implement it by yourself. Usage of Thread gives you more control over the async process execution (e.g. thread priority or choosing beetween foreground/background thread type).
Is background thread C#?
Background threads are threads which will get terminated when all foreground threads are closed. The application won’t wait for them to be completed. We can create a background thread like following: Thread backgroundThread = new Thread(threadStart);
What is the difference between foreground and background thread?
Background threads are identical to foreground threads with one exception: a background thread does not keep the managed execution environment running. Once all foreground threads have been stopped in a managed process (where the .exe file is a managed assembly), the system stops all background threads and shuts down.
Is the main thread a foreground thread?
The whole purpose of background threads is that the process will exit if the only threads left executing are background threads. The main thread needs to be a foreground thread, or the app would just immediately exit.
