c# - Linq JObject query -

i have problems jobject , jarray linq query. error:

unable cast object of type 'newtonsoft.json.linq.jobject' type     'newtonsoft.json.linq.jarray'. 

my code:

string fetchresult = jsonconvert.serializeobject(sidebar, formatting.indented); jobject rss = jobject.parse(fetchresult);  var jsonmodel = item in (jarray)rss["registrationcase"]                         select new datalist                         {                             registrationtypename = item["registrationtypename"].value<string>(), }; 

if remove (jarray) get: cannot access child value on newtonsoft.json.linq.jproperty.

json, jobject: e.g: want registrationtypename, firstname , value of journalnumber.

{ "status": null, "registrationcase": { "registrationtypename": " ", "expiredate": null, "personid": 7, "person": {   "firstname": " ",   "gendervalue": 2,   "gender": 2, }, "userid": 7, "user": {   "username": "no-dom\\wme",   "lastname": null,   "id": 7, }, "transactions": [], "comments": [], "customdata": [   {     "key": "journalnumber",     "value": "0654-84148-00000-25",     "id": 3,   },   {     "key": "isconsentgiven",     "value": "false",     "id": 4,   },   { ], "fileid": null, "file": null, "id": 7,  } } 

u can these values directly :

   var registrationtypename = rss["registrationcase"]["registrationtypename"];    var firstname = rss["registrationcase"]["person"]["firstname"];    var journalnumber = rss["registrationcase"]["customdata"][0]["value"];
