Threading in .net

Question

I have a simple example of a winforms application where i choose a directory in a directory chooser and click a button to loop through the directory and copy each file in the directory into another directory.

i want to do the file copy on a background thread to avoid locking the GUI.

i am looking for the simplest solution to:

Create the background thread
Pass the source and destinations in
Get a callback on progress so i can show a progress bar on the GUI thread

I would recommend using the BackgroundWorker class.

Example.

In addition to the above answer, I'd add that the BackgroundWorker is ideal for this as it can give you progress updates too. Just make sure you prevent reentry - that is you need to prevent the situation where the user could start the background worker again before it has completed.
