但是，这一个很好：

       [Authorize]
    [NewHireFilter]
    public ActionResult ModuleOne()
    {
        ModuleOneViewModel vm = new ModuleOneViewModel();
        HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
        FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);
        Int32 newHireID = Convert.ToInt32(ticket.Name);

        vm.newHire = dbContext.Employees.FirstOrDefault(e => e.EmployeeID == newHireID);

        return View(vm);
    }

再一次，我非常感谢任何帮助，因为这对我来说是一个令人困惑的问题

谢谢。

警告！您似乎正在数据库中以明文形式存储密码。这是一个严重的安全违规行为！密码不应该像那样存储。它们应该是单向散列和加密的，您应该比较散列形式的密码以确定有效性。看起来在视图的“编译版本”（NewHire\u NewEmpForm\u cshtml）中发生了异常。未设置某些对象实例。你能发布你所有的cshtml吗？当然可以；我已经为应该加载的视图添加了chtml。谢谢@mason的可能副本是一个很好的资源，但我不认为它有助于解决我的问题。我看到的最相关的数据是确保您实际上正在向视图传递模型。我是。此外，我还编辑了上面的代码，以说明非常相似的控制器/视图组合可以很好地工作。

    [Authorize]
    [NewHireFilter]
    public ActionResult NewEmpForm()
    {
        HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
        FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);
        Int32 newHireID = Convert.ToInt32(ticket.Name);
        Employee newEmp;

        newEmp = dbContext.Employees.FirstOrDefault(e => e.EmployeeID == newHireID);

        return View(newEmp);
                }
