Ah, you want a header-less CSV file? You then need to instantiate your CsvDataContext with a CsvConfiguration that specifies CsvConfiguration.NO_COLUMN_NAME_LINE as the 'columnNameLineNumber' property. If you otherwise want defaults, that would be like this:
new CsvConfiguration(CsvConfiguration.NO_COLUMN_NAME_LINE); 2014-07-16 23:14 GMT+02:00 Júnior <[email protected]>: > Right, what I'd like to know is to create the table without the header, I > think the only way would be changing the CsvCreateTableBuilder. > Thanks, > > > > 2014-07-16 18:12 GMT-03:00 Kasper Sørensen <[email protected] > >: > > > Hmm actually I just now realized that you can completely omit the Drop > > Table part ... if you use create table on an empty file, it will simply > > create the header. > > > > > > 2014-07-16 23:10 GMT+02:00 Kasper Sørensen < > [email protected] > > >: > > > > > Yes, you do that while creating the table.
