title: Looping over ILookup, accessing values
body: <p>I've got a <code>ILookup&lt; string, List&lt;CustomObject&gt; &gt;</code> from some linq I've done. </p>
  
  <p>I'd like to now iterate over the results: </p>
  
  <pre><code>foreach(IGrouping&lt;string, List&lt;CustomObject&gt;&gt; groupItem in lookupTable)
  {
      groupItem.Key; //You can access the key, but not the list of CustomObject
  }
  </code></pre>
  
  <p>I know I must be misrepresenting a <code>IGrouping</code> as a <code>KeyValuePair</code>, but now I'm not sure how to access it properly. </p>
