次のエラーが表示されます。
Error 1; expected(Line 67, "for (string dir in directions)" )
Error 2; expected(LINE 67, " " )
Error 3 'string' does not contain a definition for 'split' and no extension method 'split' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?) (LINE 20, var fields = line.split (","); )
