title: How to get values out of IGrouping?
body: <p>I have applied IGrouping&lt;> over a list - here's what it looks like:</p>
  
  <pre><code>IEnumerable&lt;IGrouping&lt;TierRequest,PingtreeNode&gt;&gt; Tiers
  {
      get { return ActiveNodes.GroupBy(x =&gt; new TierRequest(x.TierID, x.TierTimeout, x.TierMaxRequests)); }
  }
  </code></pre>
  
  <p>Later in my code I iterate over Tiers. Its simple to get the key data using the Key element, but how do I get the <code>IEnumerable&lt;PingtreeNode&gt;</code> that forms the value part?</p>
  
  <p>Thanks in advance</p>
