angularjs - When send individual parameter, action result cannot be hit. when send object, it gets hit -

i have 1 application consist of asp.net webapi 2 , web project angularjs used. problem when call api parameters, not hit. , when send object, gets hit.

anjularjs code:

with parameters

$http({     cache: false         , method: 'post'         , url: 'http://localhost:51341/api/user/updateuser'         , data: { userid: $scope.usersid, fullname: $scope.name } }).success(function (data, status, headers, config) { }) .error(function (data, status, headers, config) { }); 

webapi code

[httppost] public apiresponse updateuser(int userid, string fullname) {     return this.response(true, messagetypes.success, "user has been saved successfully."); } 

with object

var model = { userid: $scope.usersid, fullname: $scope.name }; $http({     cache: false         , method: 'post'         , url: 'http://localhost:51341/api/user/updateuser'         , data: model }).success(function (data, status, headers, config) { }) .error(function (data, status, headers, config) { }); 

webapi code

[httppost] public apiresponse updateuser(user model) {     return this.response(true, messagetypes.success, "user has been saved successfully."); } 

user class

public class user {     public int userid { get; set; }     public string fullname { get; set; }     public int age { get; set; }     public string address1 { get; set; }     public string address2 { get; set; } } 

when call made parameters, api not hit. when call made object, api gets hit.

what missed when call made parameters ? appreciated.

from webapi docs:

at 1 parameter allowed read message body. not work:

// caution: not work!     public httpresponsemessage post([frombody] int id, [frombody] string name) { ... }
