How do I get the full url of the page I am on in C#

Question

I need to be able to get at the full URL of the page I am on from a user control. Is it just a matter of concatenating a bunch of Request variables together? If so which ones? Or is there a more simpiler way?

Answer 1

I usually use Request.Url.ToString() to get the full url (including querystring), no concatenation required.

Answer 2

Here is a list I normally refer to for this type of information:

Request.ApplicationPath :   /virtual_dir
Request.CurrentExecutionFilePath :  /virtual_dir/webapp/page.aspx
Request.FilePath :  /virtual_dir/webapp/page.aspx
Request.Path :  /virtual_dir/webapp/page.aspx
Request.PhysicalApplicationPath :   d:\Inetpub\wwwroot\virtual_dir\
Request.QueryString :   /virtual_dir/webapp/page.aspx?q=qvalue
Request.Url.AbsolutePath :  /virtual_dir/webapp/page.aspx
Request.Url.AbsoluteUri :   http://localhost:2000/virtual_dir/webapp/page.aspx?q=qvalue
Request.Url.Host :  localhost
Request.Url.Authority : localhost:80
Request.Url.LocalPath : /virtual_dir/webapp/page.aspx
Request.Url.PathAndQuery :  /virtual_dir/webapp/page.aspx?q=qvalue
Request.Url.Port :  80
Request.Url.Query : ?q=qvalue
Request.Url.Scheme :    http
Request.Url.Segments :  /
    virtual_dir/
    webapp/
    page.aspx

Hopefully you will find this useful!

Answer 3

Request.Url.AbsoluteUri

This property does everything you need, all in one succinct call.

Answer 4

Request.RawUrl

Answer 5

if you need the full URL as everything from the http to the querystring you will need to concatenate the following variables

Request.ServerVariables("HTTPS") // to check if it's HTTP or HTTPS
Request.ServerVariables("SERVER_NAME") 
Request.ServerVariables("SCRIPT_NAME") 
Request.ServerVariables("QUERY_STRING")

Answer 6

For ASP.NET Core you'll need to spell it out:

@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.Path}{Context.Request.QueryString}")

Or you can add a using statement to your view:

@using Microsoft.AspNetCore.Http.Extensions

then

@Context.Request.GetDisplayUrl()

The _ViewImports.cshtml might be a better place for that @using

Answer 7

Better to use Request.Url.OriginalString than Request.Url.ToString() (according to MSDN)

Answer 8

Thanks guys, I used a combination of both your answers @Christian and @Jonathan for my specific need.

"http://" + Request.ServerVariables["SERVER_NAME"] +  Request.RawUrl.ToString()

I don't need to worry about secure http, needed the servername variable and the RawUrl handles the path from the domain name and includes the querystring if present.

Answer 9

If you need the port number also, you can use

Request.Url.Authority

Example:

string url = Request.Url.Authority + HttpContext.Current.Request.RawUrl.ToString();

if (Request.ServerVariables["HTTPS"] == "on")
{
    url = "https://" + url;
}
else 
{
    url = "http://" + url;
}

Answer 10

Try the following -

var FullUrl = Request.Url.AbsolutePath.ToString();
var ID = FullUrl.Split('/').Last();
