c# - jQuery cannot deserialize json object properly -

i cannot succeed deserialize json object passed c# code behind. have been working on 3 hours , couldn't understand reason.

here json object creation

struct specialitiy_struct {     public int id;     public string name; };  [webmethod] public static string get_specialities(string professionalid) {     database db = databasefactory.createdatabase("connection");     dbcommand dbcommand;     dbcommand = db.getstoredproccommand("select_profes_speciality");     db.addinparameter(dbcommand, "prof_id", dbtype.int16, convert.toint16(professionalid));     idatareader dr = db.executereader(dbcommand);      list<specialitiy_struct> my_list = new list<specialitiy_struct>();     specialitiy_struct my_speciality;      while (dr.read()) {         my_speciality = new specialitiy_struct();         my_speciality.id = convert.toint16(dr["specialtyid"].tostring().trim());         my_speciality.name = dr["specialtyname"].tostring().trim();         my_list.add(my_speciality);     }     javascriptserializer serializer = new javascriptserializer();     return serializer.serialize(my_list); } 

and here jquery code deserialize json object

$.ajax({      type: "post",      url: "notificationsettings.aspx/get_specialities",      data: "{'professionalid':'" + <%= session["proflid"].tostring().trim() %> + "'}",      contenttype: "application/json; charset=utf-8",      datatype: "json",      success: function (data, status) {        $.each(data, function (dt) {           var mydata = data.d;           var obj = $.parsejson(mydata);           $("#txt_speciality").tokeninput("add", { name: obj.name, id: obj.id});        });      } }); 

the returned json object this

 d: "[{"id":67,"name":"kardiyoloji"},{"id":1,"name":"acil tip"}]" 

i cannot deserialize json object properly, please me it?

your problem (partly) because data.d array of objects, not single object, can't access name , id properties of useful information (it doesn't have any). suspect should doing iterating on data.d, not data, so:

var d = $.parsejson(data.d); $.each(d, function(index, dt) {     $("#txt_speciality").tokeninput("add", { name: dt.name, id: dt.id}); }); 

if you're returning valid json server there should no need parse yourself. if you're returning json object has json string properties should change since there's absolutely no need way.
