How can I split a string using regex to return a list of values?

Question

How can I take the string foo[]=1&foo[]=5&foo[]=2 and return a collection with the values 1,5,2 in that order. I am looking for an answer using

Answer 1

This should do:

using System.Text.RegularExpressions;

Regex.Replace(s, !@"^[0-9]*$”, "");

Where s is your String where you want the numbers to be extracted.

Answer 2

I don't know C#, but...

In java:

String[] nums = String.split(yourString, "&?foo[]");

The second argument in the String.split() method is a regex telling the method where to split the String.
