… SendJoinMessage(string Message)

private void SendJoinMessage(string Password)

SendIrcMessage("NICK " + UserName);
SendIrcMessage(“USER " + UserName + " 8 * :” + UserName);
SendIrcMessage(“JOIN #” + Channel);

SendIrcMessage(“CAP REQ :twitch.tv/tags”);
}

send or read is just trying to read or write use in StreamReader/Writer in asynchronous Method…

10054 socket error message seems like go wrong in first handshake or in connect moment,

but i only catch it in StreamWriter.ReadLineAsync()… at that moment.

how can i verify the connection is valid?

I already try to do in dataAvaliable or ConnectAsync…
(only i can do is maybe convert it in to use callback or delegate event)

i think many others don’t create socket connection in constructor…
(it can’t use async/await/ task)

anyway… the question is how can i verify the connection is valid?
