c# - Deserialise JSON and access content using Linq to JSon -

i have following json stored in cookie wish parse:

{"package":[{"id":"5054","nodeid":"3286"},{"id":"8888","nodeid":"7777"}], "hotel":[{"id":"3421","nodeid":"1234"},{"id":"8748","nodeid":"2435"}], "activity":[{"id":"5054","nodeid":"3286"},{"id":"8888","nodeid":"7777"},{"id":"2131","nodeid":"2342"}]} 

i understand accepted answer on question deserializing json .net object using newtonsoft (or linq json maybe?) can use following code access individual objects within json notation:

jtoken token = jobject.parse(stringfullofjson);  int page = (int)token.selecttoken("page"); int totalpages = (int)token.selecttoken("total_pages"); 

i've therefore adapted code follows:

httpcookie cookie = request.cookies.get("wishlist"); string jsonstring = string.empty; string nodeid = string.empty;  if (cookie != null) {     jsonstring = cookie.value;     jtoken token = jobject.parse(jsonstring); } 

i wish retreive package array example , loop through each of items in array , output ids in following format:

5054,8888 

from example code sort of came following approach i'm not sure if i'm proceeding in right direction.

jobject obj = jobject.parse(jsonstring); jarray packages = (jarray)obj["package"]; 

what best way of specifying 1 of arrays eg. hotel, package , looping through contents , outputting each of id nodes found? nodeid numeric id string or int adds layer of complication.

any appreciated , apologise if sumwhat stupid or easy question have jsut started working .net , oo of concepts still bit foggy.

here's how this, i'd create classes required deserialize json :-

    public class jsoncookie     {         public package[] package { get; set; }         public hotel[] hotel { get; set; }         public activity[] activity { get; set; }     }      public class package     {         public string id { get; set; }         public string nodeid { get; set; }     }      public class hotel     {         public string id { get; set; }         public string nodeid { get; set; }     }      public class activity     {         public string id { get; set; }         public string nodeid { get; set; }     } 

now, create method deserialising :-

public jsoncookie getjsoncookieresponse()         {             try             {                 // add own code gets response here.                  // string response = "{"package":[{"id":"5054","nodeid":"3286"},{"id":"8888","nodeid":"7777"}], "hotel":[{"id":"3421","nodeid":"1234"},{"id":"8748","nodeid":"2435"}], "activity":[{"id":"5054","nodeid":"3286"},{"id":"8888","nodeid":"7777"},{"id":"2131","nodeid":"2342"}]}";                  //return new jsonserializer().deserialize<jsoncookie>(new jsontextreader(new stringreader(response)));             }             catch             {                 return null;             }         } 

from jsoncookie object returned, can use linq pick out need follows :-

x.package.select(p=>p.id);
