One of the convenient automations uses a well-known algorithm.

String matching algorithms: 

Void PrintMatch(String text, string pattern) 

{ 

Regex r = new Regex(pattern, options); 

Int[] gnums = r.GetGroupNumber(); 

Match m = r.Match(text); 

While (m.Success) 

{ 

Group g = m.Groups[gnums[i]]; 

CaptureCollection cc = g.Captures; 

For (int j = 0; j < cc.Count; j++) 

{ 

capture c = cc[j]; 

Console.WriteLine(“\t\tCapture{0} = [{1}] Index={2} and Length={3}”, j, c,c.Index, c.Length); 

} 

m = m.NextMatch(); 

} 

}
