How to get URL path in C#
提问by Nomi Ali
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.aspxI want to get "http://www.MyIpAddress.com/red/green/" only. How can I get.I'm doing like
我想获得URL的所有路径，除了URL的当前页面，例如：我的网址http://www.MyIpAddress.com/red/green/default.aspx我想“ HTTP：// WWW。仅限 MyIpAddress.com/red/green/”。我怎样才能得到。我正在做
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, ""));
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."
它在 new 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”。

Don't treat it as a URI problem, treat it a string problem. Then it's nice and easy.
不要把它当作一个 URI 问题，把它当作一个字符串问题。然后它又好又容易。
String originalPath = new Uri(HttpContext.Current.Request.Url.AbsoluteUri).OriginalString;
String parentDirectory = originalPath.Substring(0, originalPath.LastIndexOf("/"));
Really is that easy!
真的是那么容易！
Edited to add missing parenthesis.

Replace this :
替换这个：
string sRet = oInfo.Name;
Response.Write(sPath.Replace(sRet, ""));
With following:
与以下：
string sRet = oInfo.Name;
int lastindex = sRet.LastIndexOf("/");
sRet=sRet.Substring(0,lastindex)
Response.Write(sPath.Replace(sRet, ""));

use this
用这个
string sPath = (HttpContext.Current.Request.Url).ToString();
sPath = sPath.Replace("http://", "");
var oInfo = new System.IO.FileInfo(HttpContext.Current.Request.RawUrl);
string sRet = oInfo.Name;
Response.Write(sPath.Replace(sRet, ""));

This may get you want you want if you're just trying to navigate to another page on your site, but it doesn't get the absolute path if you really need that. You can navigate within the site without using the absolute path.
如果您只是想导航到您网站上的另一个页面，这可能会让您想要，但如果您真的需要，它不会获得绝对路径。您可以在不使用绝对路径的情况下在站点内导航。
string loc = "";
loc = HttpContext.Current.Request.ApplicationPath + "/NewDestinationPage.aspx";
Response.Redirect(loc, true);
If you really need the absolute path, you can pick off the parts and build what you need with the Uri class:
如果您真的需要绝对路径，您可以选择部分并使用 Uri 类构建您需要的内容：
Uri myUri = new Uri(HttpContext.Current.Request.Url.AbsoluteUri)
myUri.Scheme
myUri.Host // or DnsSafeHost
myUri.Port
myUri.GetLeftPart(UriPartial.Authority) // etc.
