  <p>and I'm using Json.NET to parse it, however its giving me a null</p>
  
  <p>this is my code:</p>
  
  <pre><code>JObject o = JObject.Parse(json); // &lt;- where json is the string above
  
  string name = (string)o["responseData"];
  </code></pre>
  
  <p>BUT its giving me this error : </p>
  
  <pre>
  Can not convert {null} to String.
