ASP.. NET MVC: RouteLink从区域到根抛出异常

我们有一个ASP。. NET MVC 3 WebApp，带有一个管理区域(areaname = 'admin')。

在管理区的页面(Razor => Index.cshtml)上，我调用:

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

Route在全局中声明。像这样:

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" }
        );

资源:

Route_Name_StaticPages = "StaticPages" 
Route_Url_StaticPages  = "static"

当页面被渲染或应该被渲染时，我得到这个异常:

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，异常只在生活系统上抛出，而不是在开发系统上抛出，所以我不能真正调试它。这是IIS 7。

我还尝试调用routelink方法，但没有area参数，也会抛出异常:

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

另一个尝试调用RouteUrl，但也失败了:

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

有人能帮帮我们吗?

是iis配置问题还是区域配置错误?
