IsUserInRole 方法无法正常工作
IsUserInRole method is not working properly
以下 'if' 条件无效，即 Roles.IsUserInRole(User.Identity.Name,"teacher") 未返回任何内容（返回零）。我应该怎么做才能让它发挥作用？要求是向注册为教师的用户显示不同的页面，向注册为学生的用户显示不同的页面。
@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>
}
这是我在帐户控制器中的注册操作方法：
[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);

The FormsAuthenticationModule class constructs a GenericPrincipal object and stores it in the HTTP context. The GenericPrincipal object holds a reference to a FormsIdentity instance that represents the currently authenticated user. You should allow forms authentication to manage these tasks for you. If your applications have specific requirements, such as setting the User property to a custom class that implements the IPrincipal interface, your application should handle the PostAuthenticate event. The PostAuthenticate event occurs after the FormsAuthenticationModule has verified the forms authentication cookie and created the GenericPrincipal and FormsIdentity objects. Within this code, you can construct a custom IPrincipal object that wraps the FormsIdentity object, and then store it in the HttpContext.User property.
换句话说，您需要在覆盖的 Application_PostAuthenticateRequest 方法中创建新的 GenericPrincial（参见 Global.asax)。像这样：
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;
}
}
以下 'if' 条件无效，即 Roles.IsUserInRole(User.Identity.Name,"teacher") 未返回任何内容（返回零）。我应该怎么做才能让它发挥作用？要求是向注册为教师的用户显示不同的页面，向注册为学生的用户显示不同的页面。
