SO is full of regex questions. Why not search SO before posting another one? — Oded, Aug 02 '10 at 09:57
Why not learn regular expressions? The ones you're asking for are fairly easy once you know how regular expressions work. http://www.amazon.com/Mastering-Regular-Expressions-Jeffrey-Friedl/dp/1565922573 — Bennor McCarthy, Aug 02 '10 at 10:03
what exactly are you trying to match in the second one, do you want the entire string track0; (any track number); just track0; or the track number between the brackets? i.e (any track number) without the brackets()??? — zcourts, Aug 07 '10 at 04:04

using System.Text.RegularExpressions;
Regex emailregex = new Regex("(?<user>[^@]+)@(?<host>.+)");
Match m = emailregex.Match(s);

2) Do you want to validate all entries with that format or do you just want to get that "(any track number)" value?

First one, try searching or use Regular Expression Library

Second, try this:

Regex regex = new Regex(@"[^\d]+\d");
