What concurrent collection do I use here?

I need to be able to enumerate the collection in any order (foreach) and Add/Remove an item from any thread.

Direct access by index is not needed.

What collection do I use? Simply a List? If so, do I only have to lock on add/remove or do I have to lock on foreach also?

I want the following operations to be available on any thread.

foreach (var item in myCollection)
{
    // myCollection can be returned in any order.
}

myCollection.Add(item)

var success = myCollection.Remove(item) // returns false if the item does not exist in myCollection

You sould use ConcurrentBag for thread-safe collections, which Represents a thread-safe, unordered collection of objects, which is avaliable since .NET 4.0

note: I can't give more information because I'm not aware of the context, in which you are going to use it. Provide more information for a deeper answer.
