json.net - loop over dictionary object in c# -

i have dictionary userdata of type string object. make http call data.

internal static dictionary<string, object> userdata = null;  **userdata = newtonsoft.json.jsonconvert.deserializeobject<dictionary<string, object>>(httpdata);** 

structure of userdata this

{     "id": "12345",     "class": [         "my-user",         "college-student"     ],     "list": [         {             "a": "cse",             "b": "database"         },         {             "a": "it",             "b": "computernetwork"         }     ] } 

now have iterate on userdata retrieve value of , b. can please me in c#

the easiest way code have:

var arr = (jarray)userdata["list"];  foreach (jobject item in arr)  {     console.writeline("a: {0}", item["a"]);     console.writeline("b: {0}", item["b"]);     console.writeline(); } 

the value in userdata key "list" jarray of jobjects, each containing "a" , "b" property.

however, (better) way create few classes represent json structure:

public class listitem {     public string { get; set; }     public string b { get; set; } }  public class myclass {     public string id { get; set; }     public list<string> @class { get; set; }     public list<listitem> list { get; set; } } 

and deserialize instance of myclass instead:

var userdata = jsonconvert.deserializeobject<myclass>(json);  foreach (listitem item in userdata.list) {     console.writeline("a: {0}", item.a);     console.writeline("b: {0}", item.b);     console.writeline(); }
