每天积累一点点，

public static string GetRootURI()
{
    string AppPath = "";
    HttpContext HttpCurrent = HttpContext.Current;
    HttpRequest Req;
    if (HttpCurrent != null)
    {
        Req = HttpCurrent.Request;

        string UrlAuthority = Req.Url.GetLeftPart(UriPartial.Authority);
    if (Req.ApplicationPath == null || Req.ApplicationPath == "/")
        //直接安装在 Web 站点
        AppPath = UrlAuthority;
    else
        //安装在虚拟子目录下
    AppPath = UrlAuthority + Req.ApplicationPath;
    }
    return AppPath;
}
#endregion
