如何在C＃中获取URL路径 [英] How to get URL path in C#

问题描述

除了URL的当前页面外，我想获取URL的所有路径，例如：我的URL是 http ：//www.MyIpAddress.com/red/green/default.aspx 我想获取 http：//仅www.MyIpAddress.com/red/green/ 。我该怎么办

I want to get the all the path of URL except the current page of url, eg: my URL is http://www.MyIpAddress.com/red/green/default.aspx I want to get "http://www.MyIpAddress.com/red/green/" only. How can I get.I'm doing like

string sPath = new Uri(HttpContext.Current.Request.Url.AbsoluteUri).OriginalString; System.Web.HttpContext.Current.Request.Url.AbsolutePath;
            sPath = sPath.Replace("http://", "");
            System.IO.FileInfo oInfo = new System.IO.FileInfo(sPath);
            string sRet = oInfo.Name;
            Response.Write(sPath.Replace(sRet, ""));

它在新的System.IO.FileInfo（sPath）上显示异常，因为sPath包含 localhost / red / green / default.aspx说不支持给定路径的格式。

Its showing exception on new System.IO.FileInfo(sPath) as sPath contain "localhost/red/green/default.aspx" saying "The given path's format is not supported."

推荐答案

请勿将其视为URI问题，将其视为字符串问题。

Don't treat it as a URI problem, treat it a string problem. Then it's nice and easy.

String originalPath = new Uri(HttpContext.Current.Request.Url.AbsoluteUri).OriginalString;
String parentDirectory = originalPath.Substring(0, originalPath.LastIndexOf("/"));

真的很简单！
