title: Get first element from a dictionary
body: <p>I have the following declaration:</p>
  
  <pre><code>Dictionary&lt;string, Dictionary&lt;string, string&gt;&gt; like = new Dictionary&lt;string, Dictionary&lt;string, string&gt;&gt;();
  </code></pre>
  
  <p>I need to get the first element out, but do not know the key or value. What's the best way to do this?</p>
