Overview

In most projects, an application needs to read CSV (Comma Separated Value) files and load them into the database. Data which is used for loading into database will usually be in the form of a text file wherein data contained in the file is separated by commas. These files generally have .csv extension.

In the below example we will demonstrate how to read a CSV file using dataset.

An alternative would be to use the free library at
http://www.codeproject.com/KB/linq/LINQtoCSV.aspx

That supports tab delimited files, files with values that contain commas, international date formats, etc.

Hi and thanks ... this worked well.

It tool me a little while to work out what the string was in the da.fill statement. After some trial and error I worked out this was assigned to the tablename property.

Also worth noting that should you elect to include headers in your CSV file, those headers will be assigned to the ColumnName property and become usable in other code pieces. I found this handy when wanting to use databindings.

Thanks again.

Yes, it certanly the option. But I used similar solution to get data of 70mb text file, it allocated X10 memory in RAM. PC with 512 mb if RAM simply crashes. I used common solution for it - StreamReader.
