How to remove a single, specific object from a ConcurrentBag<>?

Question

With the new ConcurrentBag in .NET 4, how do you remove a certain, specific object from it when only TryTake() and TryPeek() are

Answer 1

This is my extension class which I am using in my projects. It can a remove single item from ConcurrentBag and can also remove list of items from bag

public static class ConcurrentBag
{
    static Object locker = new object();

    public static void Clear(this ConcurrentBag bag)
    {
        bag = new ConcurrentBag();
    }


    public static void Remove(this ConcurrentBag bag, List itemlist)
    {
        try
        {
            lock (locker)
            {
                List removelist = bag.ToList();

                Parallel.ForEach(itemlist, currentitem => {
                    removelist.Remove(currentitem);
                });

                bag = new ConcurrentBag();


                Parallel.ForEach(removelist, currentitem =>
                {
                    bag.Add(currentitem);
                });
            }

        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.Message);
        }
    }

    public static void Remove(this ConcurrentBag bag, T removeitem)
    {
        try
        {
            lock (locker)
            {
                List removelist = bag.ToList();
                removelist.Remove(removeitem);                

                bag = new ConcurrentBag();

                Parallel.ForEach(removelist, currentitem =>
                {
                    bag.Add(currentitem);
                });
            }

        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex.Message);
        }
    }
}
