It was meant for a ASP.net webforms application however you should be able to adjust the code accordingly to pump it into a forms gridview. If I have time, I’ll post a snippet.

Is the code supposed to be put into a windows form application? I get a error with

GridView1.DataBind();

‘System.Windows.Forms.DataGridView’ does not contain a definition for ‘DataBind’ and no extension method ‘DataBind’ accepting a first argument of type ‘System.Windows.Forms.DataGridView’ could be found (are you missing a using directive or an assembly reference?)

Question: if I use the ReadLinesFromFile method, does that read the entire file into memory, and allow it to be accessed as an enumerated list, or does it read one line at a time, and pass each to the query to operate? I have to operate on massive files, and will get out of memory exceptions if it is the former. Thanks!

You know, you can simplify your code a bit more by replacing... new char[] { '\t' } With simply... '\t'

var products = from line in ReadLinesFromFile(@"c:\import.txt") select new { ProductName = line.Substring(0, 12), Quantity = line.Substring(12, 3), Price = line.Substring(15, 5), Total = line.Substring(20, 10) };
