FA nfa = FA.Parse(exp);
// turn it into an optimized DFA
FA mdfa = nfa.ToMinimizedDfa();

// Make sure to reference VisualFA.Compiler:

FARunner compiledStr = mdfa.CompileString();
compiledStr.Set(text);
//or
FARunner compiledRdr = mdfa.CompileTextReader();
compiledRdr.Set(text)
// to lex (as above)
foreach(FAMatch match in <compiledStr/compiledRdr>) {
	Console.WriteLine("{0}:{1}",match.Position,match.Value);
