站点地图/面包屑在默认页面上不显示Url路由

我已经用UrlRouting设置了我的web表单站点(4.0)。

• http://Localhost/Home
• http://Localhost/List

我的主要问题是 http://Localhost/

因为它违约了 http://Localhost/default.aspx

我试图避免在sitemap xml中添加另一个元素

<siteMapNode url="~/Home" title="Home"  description="Home" aspx="default.aspx">

最好的方法是什么?

routes.MapPageRoute("IISDefault", "", "~/Default.aspx");

这是一些信息。

Routes
routes.MapPageRoute("Default", "Home", "~/Default.aspx");
routes.MapPageRoute("ListAll", "List", "~/ListAll.aspx");

Sitemap
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
    <siteMapNode url="~/Home" title="Home"  description="Home">
        <siteMapNode url="~/List" title="List All"  description="List All"  />
    </siteMapNode>
</siteMap>

XmlSiteMapProvider提供程序

   /// <summary>
    /// This is where the original sitemap node is overloaded.  We get the proper translation from the database.
    /// </summary>
    /// <param name="sender">This is the sender of the event</param>
    /// <param name="e">This is the event arguments</param>
    /// <returns>Returns a modified SiteMapNode</returns>
    /// <remarks></remarks>
    public SiteMapNode SmartSiteMapProvider_SiteMapResolve(object sender, SiteMapResolveEventArgs e)
    {

        SiteMapNode returnValue = null;

        if ((SiteMap.CurrentNode == null))
        {
            // If we don't find a sitemap node, then we might be working with UrlRouting
            returnValue = ProcessRoute(e);
        }


        return returnValue;

    }

    private SiteMapNode ProcessRoute(SiteMapResolveEventArgs e)
    {

        SiteMapNode returnValue = null;

        System.Web.Routing.RequestContext rc = HttpContext.Current.Request.RequestContext;

        if ((rc != null))
        {
            System.Web.Routing.RouteBase route = rc.RouteData.Route;

            if ((route != null))
            {
              // Play with the node (Never getting here)
            }
        }

        return returnValue;

    }
