C# dictionary key as dictionary
<p>My dictionary key is another dictionary.How can I view if my dictonary("games") ContainsKey "myname" for example ?
I have something like this : </p>

<pre><code>Dictionary&lt;string,List&lt;ChatClient&gt;&gt; rooms = new Dictionary&lt;string, List&lt;ChatClient&gt;&gt;();
Dictionary&lt;Dictionary&lt;string, List&lt;ChatClient&gt;&gt;, IGame&gt; games = new Dictionary&lt;Dictionary&lt;string, List&lt;ChatClient&gt;&gt;, IGame&gt;();

public void CreateAGame(string roomName, IGame game) {
     if (rooms.ContainsKey(roomName)) {
         games.Add(rooms, game);
     }
}
</code></pre>
