这篇文章主要介绍了获取根目录的URL的方法,需要的朋友可以参考下

代码如下: 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 == "/")  //直接安装在 Web 站点  AppPath = UrlAuthority;  else  //安装在虚拟子目录下  AppPath = UrlAuthority + Req.ApplicationPath;  }  return AppPath;  }
