這篇文章主要介紹了獲取根目錄的URL的方法,需要的朋友可以參考下
    代碼如下:
    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 == "/")
    //直接安裝在 Web 站點
    AppPath = UrlAuthority;
    else
    //安裝在虛擬子目錄下
    AppPath = UrlAuthority + Req.ApplicationPath;
    }
    return AppPath;
    }
