body: <p>I'm trying to parse JSON string that received from websocket sharp but keep failing. </p>
  
  <pre><code>using (var ws = new WebSocket(WebAddr))
  {
      ws.Log.Level = LogLevel.Debug;
      ws.OnOpen += (ss, ee) =&gt;
      {
          System.IO.File.WriteAllText(@"C:\log.txt", "connected!");
      };
      ws.OnMessage +=  (ss, ee) =&gt;
      {
          JsonValue jo = JsonValue.Parse(ee.Data);
          string value = (string)jo["levelid"];
          Console.Write(value + '\n');
      };
  }
  </code></pre>
  
  <p>It just threw exception error when reaches <code>string value...</code> part. </p>
