c# - Json Deserialization can't access attributes of object -

i got class (by using json2c#):

 public class friends {     public class datum     {         public string name { get; set; }         public string id { get; set; }      }      public class paging     {         public string next { get; set; }     }      public class summary     {         public int total_count { get; set; }     }      public class rootobject     {         public list<datum> data { get; set; }         public paging paging { get; set; }         public summary summary { get; set; }     } } 

and poor try perfom deserialization:

                datacontractjsonserializer js = new datacontractjsonserializer(typeof(friends));                 memorystream ms = new memorystream(system.text.asciiencoding.ascii.getbytes(data));                 friends x = (friends)js.readobject(ms); 

i thought should able access example friends.datum.name not work.

my question is, did wrong? how should optimise code?

i got datatemplate listview , i'm using mvvm pattern, binding should no big issue.

this example json response:

    {"data":[{"name":"xxx","id":"xxx"}],"paging":{"next":"https:\/\/graph.facebook.com\/v2.5\/xxx\/friends?access_token=x"},"summary":{"total_count":2}}         

xxx secret

you have use deserializer type of rootobject because has matching properties data, paging , summary.
