I have a huge amount of data in flat-file format that I would like to validate with Visual Basic 2010. Basically the data is a text file with 300 comma separated fields and 500,000 records.
Any tips, sample code or examples? Are any .NET classes specifically geared for data validation?
As I have different validation rules for each field (some fields are dates, some are currency, etc.) I would like to store the rules away from the code (e.g. in an SQL database table). Has anyone seen this done before?
