is there any example to post multiple objects to a controller. How the data for the ajax post have to look like ?

[HttpPost]
public string Register(UserLogin userLogin, Contact contact)

}

UserLogin

public class UserLogin

   public string Username { get; set; }
   public string Password { get; set; }
}

   public string Firstname { get; set; }
   public string Lastname { get; set; }
}

Try this

$.ajax({
   type: "POST",
   url: "SomeUrl"
   dataType: "json",
   contentType: "application/json; charset=utf-8",
   data: {
       'userLogin' : {
           'Username' : 'Username',
           'Password' : 'Password'
       },
       'contact' : {
           'Firstname' : 'Firstname',
           'Lastname' : 'Lastname'
       }
   }
});

Just need to change javascript. Pass your object like this after creating

var loginObject = {
  Username: uname,//get it using jQuery $('#Username').val()
  Password : pswrd    //same way
};
var contact = {
  Firstname = "",
  Lastname = "",
};

And in ajax call,

data: {userLogin: loginObject, contact: contactObject}

You can follow the below snippet

var userLogin = {
UserName : "", Password : ""
};

var contact = {
FirstName : "", LastName : ""
};

Then you can assin the data to the ajax call like data : {userLogin : userLogin, contact : contact}
