Streams in .net

Question

I have a simple winforms application example in which I select a directory in the selection list and click a button to scroll through the directory and copy each file to the directory in a different directory.

I want to make a copy of the file in the background thread to avoid GUI blocking.

I am looking for the simplest solution for:

• Create a background thread
• Pass the source and recipients to
• Get a callback for progress so that I can show a progress bar in the GUI thread.

Answer 1

I would recommend using the BackgroundWorker class.

An example .

Answer 2

In addition to the answer above, I would add that BackgroundWorker is perfect for this, as it can also give you updates. Just make sure that you prevent re-inclusion - you need to prevent a situation where the user can restart the background worker before it is completed.
