I am looking for one or two digits after Pic,,, in a string and adding them to a list.

Regex i am trying is @"[Pic,,,]\d{1,2}[,]"

My problem is that i find numbers that dont have Pic,,, infront of them and for example i cant find 16 in the text below.

d Ëf ˆ ƒ Digital,"> KB1-P5/6",,,,"","0,0,0","255,255,255",0,"","0,0,0","255,255,255",0,"","0,0,0","255,255,255",0,"","0,0,0","255,255,255",0 ×f DynInfo ëf Pic,,,16, ÷f PicInfo g KB1-P5/6 1g B ˆÿâY þ ]g C ÒÏ,) þ ‘g G ´\

foreach (var line in lines)
   List.Add(Regex.Match(line,@"[Pic,,,]\d{1,2}[,]").ToString());

`(?<=Pic\,\,\,)[0-9]{1,2}(?=\,)` – Dmitry Bychenko Oct 02 '18 at 07:36
*`[]` denotes character sets*. Remove the brackets. You might just capture the digits, `Regex.Match(line,@"Pic,,,(\d{1,2})(?=,)").Groups[1].Value`, too. But the main problem was the character class. – Wiktor Stribiżew Oct 02 '18 at 07:36

`var List = Regex.Matches(source, @"(?<=Pic\,\,\,)[0-9]{1,2}(?=\,)").OfType().Select(match => match.Value).ToList();` you'll get the `List` with one item: `"16"` – Dmitry Bychenko Oct 02 '18 at 07:41
Also you should do something about your encoding where you read lines as you use the wrong one. – ckuri Oct 02 '18 at 07:52
Thanks for your support! @DmitryBychenko your response solved my problem :) – Harald Oct 02 '18 at 08:14
