Answer 1

I'd use this particular pattern:

string re = @"foo\[\]=(?\d+)";

So something like (not tested):

Regex reValues = new Regex(re,RegexOptions.Compiled);
List values = new List();

foreach (Match m in reValues.Matches(...putInputStringHere...)
{
   values.Add((int) m.Groups("value").Value);
}
