var regex = new Regex(@"\(([^)]*)\)", RegexOptions.Compiled);
string secondMatch = regex.Matches(text).Cast<Match>()
    .Select(m => m.Value.Trim('(', ')'))
    .ElementAtOrDefault(1);

(?<=^[^()]*\([^)]*\)[^()]*\()[^)]*

You can simply use this.See Demo

You can try to use this regex:

\(([^)]+)\)

In C#, you can just match all the (...) substrings and then access the second one using Index 1:

var rx = @"\([^)]*\)";
var matches = Regex.Matches(str, rx).Cast<Match>().Select(p => p.Value).ToList();
var result = matches != null && matches.Count > 1 ? matches[1] : string.Empty;

See IDEONE demo

The regex matches

  • \( - an opening (
  • [^)]* - 0 or more characters other than )
  • \) - a closing ).

I can't test it but this should probably work:

\([^\)]*\)
