对于Windows程序 和Web 应用程序来说,他们运行的路径是不一样的,所以关键是判断当前运行的程序是哪种程序.于是可以使用如下的代码 string path = ""; if (System.Environment.CurrentDirectory == AppDomain.CurrentDomain.BaseDirectory)//Windows应用程序则相等 …{ path = AppDomain.CurrentDomain.BaseDirectory; } else …{ path = AppDomain.CurrentDomain.BaseDirectory + "Bin\"; }

HttpContext.Current.Request.Url.AbsoluteUri

        //获取网站根目录
        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;
        }
