Regex Replace of Mirc Colour Codes

Question

I am making a small / simple IRC client, for a special use case. I would like to strip out the Mirc colour codes other users are typing from their Mirc / other similar clients.

Screenshot :

I have been trying for approx 1hr without success :

string msg = string.Format("{0}\n", e.Data.Message);
//msg = Regex.Replace(msg, @"\x03(?:\d{1,2}(?:,\d{1,2})?)?", string.Empty); // Ive tried all sorts here.
txtActivity.AppendText(msg);

Please help, thanks in advance.

Answer 1

If you want to strip out ALL BURC codes (bold, underline, reverse and colour), you can also use a regular expression such as the following:

msg = Regex.Replace(msg, @"[\x02\x1F\x0F\x16]|\x03(\d\d?(,\d\d?)?)?", String.Empty);
