Question

I am currently using the FileHelpers library (v2.0.0.0) to parse a CSV file. The CSV file is mapped to a class that has a handful of public properties, let’s say there are N. The problem is that, by default, FileHelpers doesn’t seem to correctly handle cases where the user specifies a CSV file that has more than N-1 commas. The remaining commas just get appended to the last property value.

I figured this must be configurable via FileHelpers’ attributes, but I didn’t see anything that would ignore fields that don’t have a matching property in the record.

I looked into the RecordConditions, but using something like ExcludeIfEnds(“,”) looks like it will skip the line entirely if it ends with a comma, but I just want them stripped.

It’s possible that my only recourse is to pre-process the file and strip any trailing commas, which is totally fine, but I wanted to know if FileHelpers can do this as well, and perhaps I’m just not seeing it in the docs.

Just an idea for a hack / workaround: you could create a property called “ExtraCommas” and add it to your class, so that extra commas are serialized there and not in the real properties of your object…
