Extract a date from a text

Question

I'd like to extract an invoice date from the text of an invoice.

I'll have a string with the entire invoice text, and I don't know where the date is in the text or how the date is formatted.

How would I attack this problem? I am using C#.

This question isn't answerable in it's current state. – asawyer Jun 21 '13 at 20:52 — asawyer, Jun 21 '13 at 20:52

How about something like this? It would only handle one specific format but the regex can be adjusted for other formats.

Regex rg = new Regex(@"[01]?\d[/-][0123]?\d[/-]\d{2}");
Match m = rg.Match(string);
m.ToString();

Here is a question with a bunch of date regexes that may help. Regular Expression to match valid dates
