Regular Expression question

[holysmokes99]

I am trying to grab the last bunch of text after the last forward
slash (/) in a url string. For example, I want to match "want" from
the string "http://www.hello.com/whatever/you/want". Using "/(.+)$" as
my regular expression yields "/www.hello.com/whatever/you/want", which
of course is not what I want. Any one able to help me out?

Thanks,
Marcus

You coule use String.LastIndexOf() and String.Substring(), which is much less
expensive than a regex.

string url = "http://hello.com/foo/bar/lalala";

int index = url.LastIndexOf('/');

if (index > -1)
{
return url.Substring( index );
}

If you *really* want a regex, use "/([^/]+)$", that is: replace the "."
(meaning "any character") with "[^/]" (meaning "any char but /").
