Question

Let’s assume I have the following text:

“something [234][3243]”

I am trying to pull the values in between the square brackets. I came up with the following regex expression: .*\[(.*)\].* however this only allows me to pull the last value in between the brackets, in this example 3243. How do I pull all values, meaning get more groups within my Match object.

Answer 1

        string s = "something[234][3243]";
        MatchCollection matches = Regex.Matches(s, @"(?<=\[)\d+(?=\])");
        foreach (Match m in matches)
        {
            Console.WriteLine(m.Value);
        }

You can do this with grouping parens, but if you use the look back and look ahead, then you will not need to pull the groups out of the match.
