Question

This is what I have so far:

string s = @"http://www.s3.locabal.com/whatever/bucket/folder/guid";
string p = @".*//(.*)";
var m = Regex.Match(s, p);

However, this returns "www.s3.locabal.com/whatever/bucket/folder/guid".

Answer 1

Although Uri.Segments is probably the best way to do it, here are some alternatives:

string s = "http://www.s3.locabal.com/whatever/bucket/folder/guid";

// Uri
new Uri(s).Segments.Last();

// string
s.Substring(s.LastIndexOf("/") + 1);

// RegExp
Regex.Match(s, ".*/([^/]+*)$").Groups[1];
