如何在ASP.net MVC 5函数中传递模型引用？

Question

I have a service with a function public bool UpdateSubClient(ref SubClient subClient) which updates the database.

Subclient model is as follow

public string SubClientName { get; set; }
public string BtnText { get; set;}
public string HdrText { get; set; }
public string ReturnURL { get; set; }

I am trying to call the the UpdateSubclient as follows

SubClientService subclientservice = new SubClientService();
SubClient currentsubclient = new SubClient();
currentsubclient.SubClientName = form["SubClientName"].ToString();
currentsubclient.ClientID = Convert.ToInt32(form["ClientID"]);
currentsubclient.BtnText = form["BtnText"].ToString();
currentsubclient.HdrText = form["HdrText"].ToString();
currentsubclient.ReturnURL = form["ReturnURL"].ToString();
bool success = subclientservice.UpdateSubClient(currentsubclient);

I am getting invalid argument error and couldn't figure out the way to pass reference. Any help will be appreciated.

I made a change request to other backend developers and changed the

public bool UpdateSubClient(ref SubClient subClient)

to

public bool UpdateSubClient(SubClient subClient)

to avoid any complications. Thanks @user2864740 insisting me to research on usages of ref as parameter.
