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

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

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](

Try this :

string url = HttpContext.Current.Request.Url.AbsoluteUri;
//

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

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

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;
//

string host = uri.host
// localhost

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/"

I guess its enough to return absolute path..

Path.GetFileName( Request.Url.AbsolutePath )

using System.IO;

If you want to get

localhost:2806

then use:

HttpContext.Current.Request.Url.Authority

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..

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

use `HttpContext.Current.Request.RawUrl`

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:

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.
