Regular Expression type2

This should work:

using System;

using System.Text.RegularExpressions;

class Test

{

static void Main()

{

string input = "((G030, G031) + ALLRAD + (N63B40, N63B44) + OL + 205_AUTOMATIK)";

string re = @"^($)+(.*?)$(.*?)$(.*?)$(.*)$";

Match m = Regex.Match(input, re);

string str1 = m.Groups[1].Value;

string[] split1 = Regex.Split(m.Groups[2].Value, @",\s*");

string str3 = m.Groups[3].Value;

string[] split2 = Regex.Split(m.Groups[4].Value, @",\s*");

string str5 = m.Groups[5].Value;

foreach(string s2 in split2)

{

foreach(string s1 in split1)

{

Console.WriteLine("{0}{1}{2}{3}{4}", str1, s1, str3, s2, str5);

}

Console.ReadKey();

}
