Hi!

Sorry for late reply, been a bit busy.

Anyhow, I have tried your example, but how can I output it to a Listview?

I have the following code now:

string[] lines = File.ReadAllLines(@"C:\Users\<user>\Desktop\Test data.txt");
var barcodes = lines.Select(line => {string[] parts = line.Split(',');
return parts[2]; });
var x = barcodes.GroupBy(b => b);

Tried differnt mthoods, among other: Messagebox.Show(x.ToString());
That failed :P

Thankfull for any help.
Have a nice day!
I have a new IDE!
