Reverse-parsing - generate commandline from arguments

[j-maly]

CommandLineParser.CommandLineParser parser = new CommandLineParser.CommandLineParser();
MyCommandLineOption options = new MyCommandLineOption();
parser.ExtractArgumentAttributes(options);
parser.ParseCommandLine(args);

It would be helpfull if its possible to do this reverse for generating a command string:

MyCommandLineOption options = new MyCommandLineOption();
option.p1 = "Yes we can";
option.p2 = true;
String cmd = option.ToParameterString(); // cmd should be: "-p1 Yes we can -p2"
