How to get the URL of the current page in C#

Question

Can anyone help out me in getting the URL of the current working page of ASP.NET in C#?

Answer 1

Try this :

string url = HttpContext.Current.Request.Url.AbsoluteUri;
// http://localhost:1302/TESTERS/Default6.aspx

string path = HttpContext.Current.Request.Url.AbsolutePath;
// /TESTERS/Default6.aspx

string host = HttpContext.Current.Request.Url.Host;
// localhost

Answer 2

You may at times need to get different values from URL.

Below example shows different ways of extracting different parts of URL

EXAMPLE: (Sample URL)

http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QueryString2=2

CODE

Response.Write("<br/>Host " + HttpContext.Current.Request.Url.Host);
Response.Write("<br/>Authority: " + HttpContext.Current.Request.Url.Authority);
Response.Write("<br/>Port: " + HttpContext.Current.Request.Url.Port);
Response.Write("<br/>AbsolutePath: " + HttpContext.Current.Request.Url.AbsolutePath);
Response.Write("<br/>ApplicationPath: " + HttpContext.Current.Request.ApplicationPath);
Response.Write("<br/>AbsoluteUri: " + HttpContext.Current.Request.Url.AbsoluteUri);
Response.Write("<br/>PathAndQuery: " + HttpContext.Current.Request.Url.PathAndQuery);

OUTPUT

Host: localhost
Authority: localhost:60527
Port: 60527
AbsolutePath: /WebSite1test/Default2.aspx
ApplicationPath: /WebSite1test
AbsoluteUri: http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QueryString1=2
PathAndQuery: /WebSite1test/Default2.aspx?QueryString1=1&QueryString2=2

You can copy paste above sample code & run it in asp.net web form application with different URL.

I also recommend reading ASP.Net Routing in case you may use ASP Routing then you don't need to use traditional URL with query string.

Answer 3

Just sharing as this was my solution thanks to Canavar's post.

If you have something like this:

"http://localhost:1234/Default.aspx?un=asdf&somethingelse=fdsa"

or like this:

"https://www.something.com/index.html?a=123&b=4567"

and you only want the part that a user would type in then this will work:

String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery;
String strUrl = HttpContext.Current.Request.Url.AbsoluteUri.Replace(strPathAndQuery, "/");

which would result in these:

"http://localhost:1234/"
"https://www.something.com/"

Answer 4

if you just want the part between http:// and the first slash

string url = Request.Url.Host;

would return stackoverflow.com if called from this page

Here's the complete breakdown

Answer 5

the request.rawurl will gives the content of current page it gives the exact path that you required

use HttpContext.Current.Request.RawUrl

Answer 6

If you want to get

localhost:2806 

from

http://localhost:2806/Pages/ 

then use:

HttpContext.Current.Request.Url.Authority

Answer 7

a tip for people who needs the path/url in global.asax file;

If you need to run this in global.asax > Application_Start and you app pool mode is integrated then you will receive the error below:

Request is not available in this context exception in Application_Start.

In that case you need to use this:

System.Web.HttpRuntime.AppDomainAppVirtualPath

Hope will help others..

A search landed me at this page, but it wasn't quite what I was looking for. Posting here in case someone else looking for what I was lands at this page too.

There is two ways to do it if you only have a string value.

.NET way:

Same as @Canavar, but you can instantiate a new Uri Object

String URL = "http://localhost:1302/TESTERS/Default6.aspx";
System.Uri uri = new System.Uri(URL);

which means you can use the same methods, e.g.

string url = uri.AbsoluteUri;
// http://localhost:1302/TESTERS/Default6.aspx

string host = uri.host
// localhost

Regex way:

Getting parts of a URL (Regex)

Answer 9

I guess its enough to return absolute path..

 Path.GetFileName( Request.Url.AbsolutePath )

using System.IO;
