When doing a regular expression a user may get confused by the null/empty valid matches. It would be nice if there was a regular expression option such as IgnoreNullMatchesAndCaptures where any match that was null or subgroup capture that was null was not reported. If that bubbles up to where there is no data at all, then a match is not reported. If a capture has other siblings, only the null value is not returned and the siblings are faithfully reported.

Thanks for the feature request!

An IgnoreNullMatchesAndCaptures would be useful to add to Regex. We'll consider this for the next release of the .NET Framework after .NET 3.5.
