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

Thought I'd chime in; despite it being almost 10 years, with the advent of the cloud, getting the parent Uri is a fairly common (and IMO more valuable) scenario, so combining some of the answers here you would simply use (extended) Uri semantics:

public static Uri Parent(this Uri uri)
{
    return new Uri(uri.AbsoluteUri.Remove(uri.AbsoluteUri.Length - uri.Segments.Last().Length - uri.Query.Length).TrimEnd('/'));
}

var source = new Uri("https://foo.azure.com/bar/source/baz.html?q=1");

var parent = source.Parent();         // https://foo.azure.com/bar/source
var folder = parent.Segments.Last();  // source

I can't say I've tested every scenario, so caution advised.
