我创建一个自定义角色提供程序，我设置了授权属性指定角色在我的控制器，它的工作很好，像这样：
[Authorize(Roles="SuperAdmin")] public class SuperAdminController : Controller ...
解决方法
[AccessDeniedAuthorize(Roles="SuperAdmin")] public class SuperAdminController : Controller
AccessDeniedAuthorizeAttribute.cs：
public class AccessDeniedAuthorizeAttribute : AuthorizeAttribute
{
public override void OnAuthorization(AuthorizationContext filterContext)
{
base.OnAuthorization(filterContext);
if(filterContext.Result is HttpUnauthorizedResult)
{
filterContext.Result = new RedirectResult("~/AcessDenied.aspx");
}
}
}
