> Issue Type: Improvement
> Reporter: Marco Dissel
> Assigned To: George Aroush
> Priority: Trivial

> Another exception is raised that can be avoided.. In this case the
> fieldNumber = -1 resulting in the ArgumentOutOfRangeException
> This can be easily solved by checking (fieldNumber > -1 && fieldNumber <
> byNumber.Count)
> ps. the java version has the same problem..
