How to write a regular expression to match a set of values?

I want to check if my string holds following value 开发者_运维百科or not:

For samples:

• 4850324810111981066060
• 50104810111981066060

My condition is

48-57(1 or more time)32(or)10(or)13(then)48(then)32(or)10(or)13(then)111981066060  

Question: How to write regular expression for above condition. Parenthesis indicate occurrence.

---

(4[8-9]|5[0-7])+(32|10|13)48(32|10|13)111981066060

Check out Expresso - it allows you to build and test your regexs, and creates a C# code snippet or a .NET assembly for you right away. Highly recommended!

---

Regex regex = new Regex(@"(?:4[89]|5[0-7])+(?:32|10|13)48(?:32|10|13)111981066060");
regex.Match(string);

Didnt test though!

You can test regular expressions in .NET online using Nregex

This this:

(48|49|50|51|52|53|54|55|56|57)+(32|10|13)48(32|10|13)111981066060

EDIT: Just saw Paul answer and this really can be shortened to

(4[89]|5[0-7])+(32|10|13)48(32|10|13)111981066060

Only difference between hos and mine approaches is: he doesn't keeps grouping information (as that isn't required) and I don't care for ignore them.

You can start with the following and see if you need to make imprevements

(4[89]|5[0-7])+(32|10|13)48(32|10|13)111981066060

it might be better to split up into fields and check those fields against your business logic instead of relying on a static regexp like the above.
