UrlHelper.RouteUrl()抛出SecurityException

Question

我正在尝试在ASP.NET的Windows主机上托管一个新的GoDaddy站点。

在构建站点导航时，代码使用System.Web.Mvc.UrlHelper中的RouteUrl方法为每个页面动态生成正确的URL。

在本地，这工作得很好。然而，在GoDaddy的服务器上，显示了这个错误：

[SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]

课程内容如下所示。checkPageType()中的page.Url = _urlHelper.RouteUrl("Default", routeValues);行是抛出错误的地方。

            }
            else
            {
                result = new
                {
                    menu = parentSlug,
                    subMenu = pageSlug,
                    gallery = ""
                };
            }

            return result;
        }
    }
}

经过更多的研究，我在this page on GoDaddy's help site的帮助下找到了它。

基本上，调用UriHelper.RouteUrl会触发CAS信任级别检查。GoDaddy默认为中等信任级别，但此检查需要完全信任。按照链接文章中的以下步骤解决了问题：
