title: Easy way to convert a Dictionary<string, string> to xml and vice versa
body: <p>Wondering if there is a fast way, maybe with linq?, to convert a <code>Dictionary&lt;string,string&gt;</code> into a XML document.  And a way to convert the xml back to a dictionary.</p>
  
  <p>XML can look like:</p>
  
  <pre><code>&lt;root&gt;
        &lt;key&gt;value&lt;/key&gt;
        &lt;key2&gt;value&lt;/key2&gt;
  &lt;/root&gt;
  </code></pre>
