title: Element order in BlockingCollection<>
body: <p>I have a Download Queue implemented with <code>BlockingCollection&lt;&gt;</code>. Now I want to prioritize some Download once in a while. I thought it might be great to move some elements 'up' the Collection, like in a list, but there is no method like Remove()/AddFirst() or Move().</p>
  
  <p>What's the preferred way of arranging items in a <code>BlockingCollection&lt;&gt;</code> ?</p>
