Getting the first instance of the matching string from a string using regular expression (confusing?!)

Question

Hello Let me explain. I have a string bigstring = 1234abcd4. Now i want to get all the substrings starting with 1 and ending with 4 in the bigstring. So i wrote this code. Regex reg = new Regex(1(.*)4); Match matches = reg.Match(bigstring); string matchstr = matches.Groups[0].Value; But i'm always getting 1234abcd4 and i want 1234 which is the first instance that matches. How can we do that? Any ideas? Thank you.

Thanks for your reply. The string i used is an example. It isn't the exact pattern of the string. The string i get is a http response (html) of a page. I'll get substrings based on html tags. Any ideas? Thank you.
