This is the cleanest way I found of doing it. You can't do it with foreach loops as by removing an item, you are changing what you are iterating through. Its more of a safety mechanism than an error. This works both ways.

Code:

  private void SwapItems(ListBox source, ListBox dest)
        {
            while (source.SelectedItems.Count != 0)
            {
                dest.Items.Add(source.SelectedItem);
                source.Items.Remove(source.SelectedItem);
            }
        }
