my json deserializable code

class login {      [datacontract]     public class user     {          [datamember]         public float version { get; set; }          [datamember]         public string vuser { get; set; }           [datamember]         public int32 id { get; set; }           [datamember]         public string hd { get; set;}          [datamember]         public string verify { get; set; }           [datamember]         public int32 key { get; set; }          public class rootobject         {              public list<user> user { get; set; }             // public int success { get; set; }          } 

and jsoncode

[{"rv":1.2,"verifieduser":"test","id":"1234","hd":"li","verify":"newuser","key":"1234"}]

it returns me error

"not code paths return value"

help me ,i'm struck in it

your method readtoobject, should return login, has no returnstatement. it's in comment:

//return deserializeduser; 

update:

the brackets of code snippet don't match. have 3 opening brackets { , 5 closing }. i.e. code blocks not grouped expected. can cause error.
