复制代码 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;

}
