.NET equivalent of Android SDK's AsyncTask (i need to display a progress bar while executing operations on a backround thread)

I'm in a basic C# .NET 4.0 WinForms application. What i want to do is to write some logic to display a progress bar on the GUI thread while executing background operations on a background thread.

Android has implemented AsyncTask class which has some methods that need override: onPreExecute, doInBackground, onProgressUpdate and onPostExecute. OnPreExecute you can show the progress bar and on PostExecute (when the doInBackground method returns) you can hide it.

I read here that .NET 4.5 comes with something similar built in. Is there anything similiar in .NET 4.0? If not, is it a good idea to implement something like android's AsyncTask or is there a more conventional way to do this in C#?

Regards,

Dan

You can create your own abstract class by using BackgroundWorker as described here AsyncTask using BackgroundWorker

Take a look at BackgroundWorker class. It provides all the functionality you described.

Closest thing in .NET would be the BackgroundWorker class, using these events:

  • DoWork - Occurs when RunWorkerAsync is called.
  • ProgressChanged - Occurs when ReportProgress is called.
  • RunWorkerCompleted - Occurs when the background operation has completed, has been canceled, or has raised an exception.
