For starters, I wouldn't use a Regex: use string.Split instead:
string[] lines = File.ReadAllLines(filePath);
var barcodes = lines.Select(line => {string[] parts = line.Split(','); 
                                     return parts[2]; });
You can then use GroupBy to combine them and get the Key - the barcode number - and it's Count:
var x = barcodes.GroupBy(b => b);
