Is Parallel.ForEach in ConcurrentBag thread safe

Question

Description of ConcurrentBag on MSDN is not clear:

Bags are useful for storing objects when ordering doesn\'t matter, and unlike sets, bags support duplicates. C

Answer 1

That looks fine to me. The way you're using it is thread-safe.

If you could return an IEnumerable, it could be made more efficient by not copying to a List when you're done.
