Getting the parent name of a URI/URL from absolute name C#

Question

Given an absolute URI/URL, I want to get a URI/URL which doesn\'t contain the leaf portion. For example: given http://foo.com/bar/baz.html, I should get http://foo.com/bar/.

Answer 1

Shortest way I found:

static Uri GetParent(Uri uri) {
    return new Uri(uri, Path.GetDirectoryName(uri.LocalPath) + "/");
}

Answer 2

new Uri(uri.AbsoluteUri + "/../")

Answer 3

There must be an easier way to do this with the built in uri methods but here is my twist on @unknown (yahoo)'s suggestion.
In this version you don't need System.Linq and it also handles URIs with query strings:

private static string GetParentUriString(Uri uri)
{
    return uri.AbsoluteUri.Remove(uri.AbsoluteUri.Length - uri.Segments[uri.Segments.Length -1].Length - uri.Query.Length);
}

Answer 4

Get segmenation of url

url="http://localhost:9572/School/Common/Admin/Default.aspx"

Dim name() As String = HttpContext.Current.Request.Url.Segments

now simply using for loop or by index, get parent directory name

code = name(2).Remove(name(2).IndexOf("/"))

This returns me, "Common"
