title: Select IEnumerable<object> from IEnumerable<IEnumerable<object>> linq
body: <p>What I need to do is select list of nested elements, here is my query which <code>returns</code> <code>IEnumerable&lt;IEnumerable&lt;object&gt;&gt;</code> here is my linq expression:</p>
  
  <pre><code>from a in (questions.Select(x =&gt; x.AnswerList).ToList())
                             select a.Select(x =&gt; x.AnswerBasicViewModel);
  </code></pre>
  
  <p>How should I do that to make it <code>return</code> only <code>IEnumerable&lt;object&gt;</code> instead of <code>IEnumerable&lt;IEnumerable&lt;object&gt;&gt;</code>?</p>
  
  <p>Just to be clear in my sample I would like to get <code>IEnumerable&lt;AnswerBasicViewModel&gt;</code>.</p>
