Метод IsUserInRole не работает должным образом

Question

Условие «если» не работает, то есть Roles.IsUserInRole(User.Identity.Name,"teacher") ничего не возвращает (он возвращает ноль). что я должен сделать, чтобы он работал? Требование состоит в том, чтобы отображать разные страницы для регистрации пользователей в качестве преподавателя и разные страницы для регистрации пользователями в качестве учащегося.

@if (Request.IsAuthenticated && Roles.IsUserInRole(User.Identity.Name,"teacher"))//HttpContext.Current.User.IsInRole("teacher"))//User.IsInRole("teacher")) //Roles.IsUserInRole(User.Identity.Name,"teacher")) 
      { 


      <li>@Html.ActionLink("Quiz Management", "Index", "Quiz")</li>      
      <li>@Html.ActionLink("Browse Quizzes", "Index", "TakeQuiz")</li> 
      <li>@Html.ActionLink("Assignment Scheduling", "Index", "Assignment")</li> 

     } 

Это мой регистр метод действия контроллера счета:

[HttpPost] 
     [AllowAnonymous] 
     [ValidateAntiForgeryToken] 
     public ActionResult Register(RegisterModel model) 
     { 
      if (ModelState.IsValid) 
      { 
       // Attempt to register the user 
       try 
       { 
        var vRole = Request["selectRole"]; 
        // WebSecurity.InitializeDatabaseConnection(); 
        WebSecurity.CreateUserAndAccount(model.UserName, model.Password); 
        WebSecurity.Login(model.UserName, model.Password); 
        if (vRole.Equals("teacher")) 
        { 
         Roles.AddUserToRole(model.UserName, "teacher");//AddUserToRole(model.UserName, "teacher"); 
        } 
        else 
        { 
         Roles.AddUserToRole(model.UserName, "student"); 
        } 
        return RedirectToAction("Index", "Home"); 
       } 
       catch (MembershipCreateUserException e) 
       { 
        ModelState.AddModelError("", ErrorCodeToString(e.StatusCode)); 
       } 
      } 

      // If we got this far, something failed, redisplay form 
      return View(model); 
     }

Я думаю, что я что-то не хватает? Что мне делать, чтобы исправить это? С уважением.

Класс FormsAuthenticationModule строит GenericPrincipal объект и сохраняет его в контексте HTTP. Объект GenericPrincipal содержит ссылку на экземпляр FormsIdentity, который представляет пользователя, прошедшего проверку подлинности. Вы должны разрешить проверку подлинности форм для управления этими задачами для вас. Если ваши приложения имеют особые требования, такие как установка свойства User в пользовательский класс, который реализует интерфейс IPrincipal, ваше приложение должно обрабатывать событие PostAuthenticate. Событие PostAuthenticate происходит после того, как FormsAuthenticationModule проверил файл cookie проверки подлинности форм и создал объекты GenericPrincipal и FormsIdentity. Внутри этого кода вы можете создать пользовательский объект IPrincipal, который обертывает объект FormsIdentity, а затем сохраняет его в свойстве HttpContext.User.

Другими словами, вам нужно создать новый GenericPrincial в переопределен Application_PostAuthenticateRequest методом (см Global.asax). Что-то вроде этого:

protected void Application_PostAuthenticateRequst(object sender, EventArgs e) 
{ 
    if (Context.User.Identity.IsAuthenticated 
    && Context.User.Identity.AuthenticationType == "Forms") 
    { 
     // You should get roles in the user by his UserName: 
     // string[] roles = ... 
     // With Role provider it will look like 
     var roles = Roles.GetRolesForUser(Context.User.Identity.Name); 

     Context.User = new GenericPrincipal(Context.User.Identity, roles); 
     Thread.CurrentPrincipal = Context.User; 
    } 
}
