Hi,
why don't you just create a view on Access with the data and schema you want to export to CSV and then just make a loop on C# that concatenates the cell values of each row separated by ';'  ?

Each loop would do a WriteLine to the StreamWriter of the concatenated strings... that's it... :)

I was going to write it but decided to do a little google search first so here's a sample code of it:

http://dotnetguts.blogspot.com/2007/01/exporting-datatable-to-csv-file-format.html

I'm attaching the same code but better formatted and I changes the sparator from ',' to ';'
This is just because if you have numeric values and depending on your region the comma may be a problem.

cheers
