and here nice tester used: http://regexstorm.net/tester

using system.text.regularexpressions;   string input = "for(i=0;i<10;i++)";         string pattern = @"^(\w+)(\w)(\w)(\w).*$";         matchcollection matches = regex.matches(input, pattern);          string cycle = matches[0].groups[1].value;         string agrupation = matches[0].groups[2].value;         string variable = matches[0].groups[3].value;         string asignation = matches[0].groups[4].value;          string test = string.format("cycle: {0}, agrupation: {1}, variable={2}, asignation: {3}", cycle, agrupation, variable, asignation);          console.writeline(test);
