ASP.NET MVC:返回视图时服务器验证和保留URL参数

我目前有以下代码可以编辑客户注释。

 [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult EditNote(Note note)
    {
        if (ValidateNote(note))
        {
            _customerRepository.Save(note);
            return RedirectToAction("Notes", "Customers", new { id = note.CustomerID.ToString() });
        }
        else
        {
            var _customer = _customerRepository.GetCustomer(new Customer() { CustomerID = Convert.ToInt32(note.CustomerID) });
            var _notePriorities = _customerRepository.GetNotePriorities(new Paging(), new NotePriority() { NotePriorityActive = true });

            IEnumerable<SelectListItem> _selectNotePriorities = from c in _notePriorities
                                                                select new SelectListItem
                                                                {
                                                                    Text = c.NotePriorityName,
                                                                    Value = c.NotePriorityID.ToString()
                                                                };

            var viewState = new GenericViewState
            {
                Customer = _customer,
                SelectNotePriorities = _selectNotePriorities
            };

            return View(viewState);
        }


    }

如果验证失败,我希望它再次呈现EditNote视图,但为类似这样的内容保留URL参数(noteid和customerid):“ http://localhost:63137/Customers/EditNote/?NoteID=7&CustomerID=28 “

关于如何实现这一点有什么想法吗?

谢谢!
