首先，您不想在母版页中执行此逻辑。您想要创建一个局部视图，该视图将根据某个控制器中的子操作返回的模型信息构建菜单。例如：

您应该将此逻辑移动到一些负责构建导航的控制器中。在此控制器内部，您应该声明一个返回所需信息的子操作。

如果您计划将 URL 和描述存储在数据库中，那么您也可以将访问权限存储在表中。这样，您可以传递用户的组或用户名并检索该用户有权访问的 URL 集合。之后，您可以使用类似于下面的代码。

例如：

public class NavigationController : Controller
{
    [ChildActionOnly]
    public PartialViewResult GetMenuForUser()
    {
        var model = _securityLayer.GetUrlForUser(HttpContext.User.Identity.Name);

        return PartialView("_UserMenu", model);
    }
}

您的 _UserMenu.cshtml 可能类似于：

@model IEnumerable<SomeCollection>

@foreach(var url in Model) {
    <li><a class="ajax-link" href="@url.Url">@url.Description</a></li>
}

然后在您的母版页中，您想要使用您将调用的菜单：

<div class="well nav-collapse sidebar-nav">
    <ul class="nav nav-tabs nav-stacked main-menu">
        <li class="nav-header hidden-tablet">MAIN MENU</li>
        @{ Html.RenderAction("GetMenuForUser", "Navigation"); }
    </ul>
</div>

无论您是否将用户访问权限存储在数据库中，这都应该让您了解如何进行操作。

更新：对不起，我后来意识到您使用的是 ASPX View Engine 而不是 Razor。您需要将我的标记转换为 ASPX View Engine。

尝试创建一个控制器，在其中使用身份获取当前用户角色的 IList，然后将该列表转换为用逗号分隔的字符串，然后根据您的偏好将其存储在 viewbag 或 tempdata 中，然后在布局中使用 Viewbag 数据显示项目基于在那里找到的角色。这是控制器

        [Authorize]
    public ActionResult Index()
    {
        if (User.Identity.IsAuthenticated)
        {
            var user = User.Identity;
            ViewBag.Name = user.Name;
            ViewBag.DisplayMenu = UserRole();
            return View();
        }
        else
        {
            ViewBag.Name = "Not Logged in";
        }
        return View();
    }
    public string UserRole()
    {
        string urole = "non";
        if (User.Identity.IsAuthenticated)
        {
            var user = User.Identity;
            ApplicationDbContext context = new ApplicationDbContext();
            var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));
            var s = UserManager.GetRoles(user.GetUserId());
            urole = String.Join(",", s.ToArray());
        }
        return urole;
    }
