Extract sub-directory name from URL in ASP.NET C#

Question

I want to be able to extract the name of a sub-directory of a URL and save it to a string from the server-side in ASP.NET C#. For example, lets say I have a URL that looks like this:

http://www.example.com/directory1/directory2/default.aspx

How would I get the value 'directory2' from the URL?

Answer 1

Uri class has a property called segments:

var uri = new Uri("http://www.example.com/directory1/directory2/default.aspx");
Request.Url.Segments[2]; //Index of directory2

Answer 2

This is a sorther code:

string url = (new Uri(Request.Url,".")).OriginalString

Answer 3

I'd use .LastIndexOf("/") and work backwards from that.

Answer 4

You can use System.Uri to extract the segments of the path. For example:

public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        var uri = new System.Uri("http://www.example.com/directory1/directory2/default.aspx");
    }
}

Then the property "uri.Segments" is a string array (string[]) containing 4 segments like this: ["/", "directory1/", "directory2/", "default.aspx"].
