I recommend you use a CSV parser rather than using the OLEDB data provider.

Search and you'll find many (free) candidates. Here are a few that worked for me:

A portable and efficient generic parser for flat files (easiest to use, IMO)
A Fast CSV Reader (easy to use, great for large data sets)
FileHelpers library (flexible, includes code generators, bit of a learning curve)

Typically these will allow you to specify properties of your CSV (delimiter, header, text qualifier, etc.) and with a method call your CSV is dumped to a data structure of some sort, such as a DataTable or List<>.

If you'll be working at all with CSV, it's worth checking out a CSV parser.
