ASP.NET MVC：從區域到根的RouteLink拋出異常

Question

我們有一個ASP.NET MVC 3 WebApp，其中包含一個管理區域（areaname ='admin'）。

在管理區域中的頁面（Razor => Index.cshtml）上，我稱：

@Html.RouteLink("Preview", Resources_Blog.Route_Name_StaticPages, new { pagename = page.Slug, area = "" }, new {target = "_blank", Request.Url.Scheme})

路線在global.asax中聲明為：

routes.MapRoute(
            Resources_Blog.Route_Name_StaticPages, // Routename
            Resources_Blog.Route_Url_StaticPages + "/{pagename}", // URL with parameters
            new { controller = "Home", action = "Page", page = UrlParameter.Optional, area = "" }, // Defaults
            new[] { "My.Namespace.Controllers" }
        );

資源是：

Route_Name_StaticPages = "StaticPages" 
Route_Url_StaticPages  = "static"

呈現頁面或應該呈現頁面時，會出現此異常：

System.Web.HttpException (0x80004005): Cannot use a leading .. to exit above the top directory.

at System.Web.Mvc.Html.LinkExtensions.RouteLink(HtmlHelper htmlHelper, String linkText, String routeName, RouteValueDictionary routeValues, IDictionary`2 htmlAttributes)

不幸的是，該異常僅拋出在livesystem上，而不是在developmentsystem上，因此我無法真正對其進行調試。 這是一個IIS 7。

我還嘗試在不使用area-parameter的情況下調用RouteLink方法也會引發異常：

Html.RouteLink("Preview", Resources_Blog.Route_Name_StaticPages, new { pagename = page.Slug, area = "" }, new {target = "_blank", Request.Url.Scheme})

另一種嘗試是調用RouteUrl，但也失敗了：

<a target="_blank" href="@Url.RouteUrl(Resources_Blog.Route_Name_StaticPages, new { pagename = page.Slug })">@Resources_Administration.Pages_StaticPage_Show</a>

有人可以幫我們嗎？

是IIS配置問題還是區域配置錯誤？

Answer 1

“解決”問題。

VA測試成功地注入了包含“ \\ .. \\ .. \\ .. \\ .. \\ .. \\ ..”的彈頭。 因此該異常被正確拋出。
