client method, making request web api

httpclient client = new httpclient();                 client.baseaddress = new uri("http://localhost:57752");                 httpresponsemessage response = client.getasync("api/auth/login/" + user.username + "/" + user.password).result;                 jsonresult result = null;                 if (response.issuccessstatuscode)                 {                     result = response.content.readasasync<jsonresult>().result;                     javascriptserializer json_serializer = new javascriptserializer();                     user validuser = json_serializer.deserialize<user>(result.data.tostring());//throws exp.                 }

i want put object instance returned api validuser..

error message:

cannot convert object of type 'system.string' type 'mongodb.bson.objectid'

here models:

public abstract class entitybase {     [bsonid]     public objectid id { get; set; } }  public class user : entitybase     {         //public string _id { get; set; }         [required]         [stringlength(100, errormessage = "the {0} must @ least {2} characters long.", minimumlength = 5)]         [datatype(datatype.text)]         [display(name = "username")]         public string username { get; set; }          [required]         [stringlength(100, errormessage = "the {0} must @ least {2} characters long.", minimumlength = 6)]         [datatype(datatype.password)]         [display(name = "password")]         public string password { get; set; }          public void encryptpassword()         {             password = encrypter.encode(this.password);         }          [datatype(datatype.password)]         [display(name = "confirm password")]         [compare("password", errormessage = "the password , confirmation password not match.")]         public string confirmpassword { get; set; }     }

you're not telling deserializer deserialize to. this

user validuser = (user)json_serializer.deserializeobject(result.data.tostring());

deserializes object , attempts cast object user, going fail. need use generic method:

user validuser = json_serializer.deserialize<user>(result.data.tostring());

it's entirely possible need more work if json names , class names/struictures different changing property names serializing.
