Fiddler access nested json to modify

[Denni]

i somehow can´t reach the objects in a nested json. I easily can reach the element test, but how to reach this_month inside "stats"? this is my json:

 

{"test":"OK","stats":{"this_month":"1653","this_week":"1653"}}

sorry, accidentialy posted. here is my code:

var oResponseBody = oSession.GetResponseBodyAsString();
       JSON.JSONParseResult oJSON = JSON.JsonDecode(oResponseBody) as JSON.JSONParseResult;
       Hashtable oObj = oJSON.JSONObject as Hashtable;

       oObj["stats"]["this_month"] = "changed";




        var modBytes = Fiddler.WebFormats.JSON.JsonEncode(oObj);

       // Convert json to bytes, storing the bytes in request body
       var mod = System.Text.Encoding.UTF8.GetBytes(modBytes);
       oSession.ResponseBody = mod;
