Getting only the Referrer page not complete address in .NET

Question

Hi,

I am using C#. Below is my sample code.

private void Page_Load(object sender, System.EventArgs e)
{
    string str = Request.UrlReferrer.ToString();   
    Label1.Text = str;  
}

The result in Label1.Text is http://localhost:82/data/WebForm1.aspx.

Now I want the result "WebForm1.aspx" in Label1.Text

can you please help me?

Thanks.

Answer 1

Try the LocalPath property on the UrlReferrer:

Label1.Text = Request.UrlReferrer.LocalPath;

It should provide you with just the filename.

Edit: this seems to also include the path, so only works for root.

In which case, you're better off just using Substring():

string str = Request.UrlReferrer.ToString();
Label1.Text = str.Substring(str.LastIndexOf('/')+1);

Answer 2

If you want only the part after the last / in the URL, calling the System.IO.Path.GetFileName() method on the Uri.LocalPath should do the trick:

System.IO.Path.GetFileName(Request.UrlReferrer.LocalPath);

If you want the output to keep query string information from the URI, use the PathAndQuery property:

System.IO.Path.GetFileName(Request.UrlReferrer.PathAndQuery);
