c# - joining a twitch IRC channel -

my function should join channel doesn't response server. weird thing when join server response. somehow, when try join channel don't receive return.

    private void join()     {         connection.writer.write("join #" + channelname.trim().tolower() + "\r\n");         console.writeline("join #" + channelname.trim().tolower() + "\r\n");         connection.writer.flush();          //debug code         while (true)         {             while (connection.reader.peek() >= 0)             {                 string line = connection.reader.readline();                 if (line.contains("ping :"))                 {                     connection.writer.write("pong :" + line.substring(line.indexof("ping :") + 6) + "\r\n");                     connection.writer.flush();                 }                 console.writeline(line);             }         }     } 

edit:

it seems twitch doesn't do

"ping :" 

but instead does

"ping " 

weirdly changing doesn't seem fixing it. 1 of moments say. "my code working , don't know why."

have @ api. seems so, it's not easy valid login. u have trigger api @ points.
