c# - TCP クライアントが IRC アドレスに接続していない

Question

私はtwitch-chatbotを構築しようとしています。私はいくつかのチュートリアルを読みましたが、これは私がこれまでにコーディングしたものです:

namespace IRC_Client
{
    class Program
    {
        public NetworkStream NetStream = null;
        public StreamReader StreamRead = null;
        public StreamWriter StreamWrite = null;

        public System.Net.Sockets.TcpClient Socket_TcpClient;

        static void Main(string[] args)
        {
            Program P = new Program();
            P.IRC_Connect();

            Console.Read();
        }

        public void IRC_Connect()
        {
            int port;
            string  nick, owner, server, oauth;

            nick = "xxx";
            Console.WriteLine("Bot Name: {0}", nick);
            oauth = "oauth:xxxxxxxxxxxxxxxxxxx";
            Console.WriteLine("Password Token: {0}", oauth);
            owner = "xxx";
            Console.WriteLine("Bot owner name: {0}", owner);
            server = "irc.twitch.tv";
            Console.WriteLine("Server name: {0}", server);                   
            port = 6667;
            Console.WriteLine("Portnummber: {0} ", port);

            try
            {
                Socket_TcpClient = new TcpClient(server, port);
            }
            catch
            {
                Console.WriteLine("Failed to connect!");
                return;
            }

            Console.WriteLine("Connected");

            IRCWork();

            try
            {
                NetStream = Socket_TcpClient.GetStream();
                StreamRead = new StreamReader(NetStream);
                StreamWrite = new StreamWriter(NetStream);
                SendData("PASS", oauth);
                SendData("NICK", nick);
            }
            catch
            {
                Console.WriteLine("Communication error");
                throw;
            }
        }

        public void SendData(string cmd, string param)
        {
            if (param == null)
            {
                StreamWrite.WriteLine(cmd);
                StreamWrite.Flush();
                Console.WriteLine(cmd);
            }
            else
            {
                StreamWrite.WriteLine(cmd + " " + param);
                StreamWrite.Flush();
                Console.WriteLine(cmd + " " + param);
            }
        }

        public void IRCWork()
        {
            string[] Text;
            string data;
            bool shouldRun = true;
            while (shouldRun)
            {
                data = StreamRead.ReadLine();
                Console.WriteLine(data);
                char[] charSeparator = new char[] { ' ' };
                Text = data.Split(charSeparator, 5);

                if (Text[0] == "PING")
                {
                    SendData("PONG", Text[1]);
                }

                if (Text.Length > 4) //is the command received long enough to be a bot command?
                {
                    string command = Text[3]; //grab the command sent

                    switch (command)
                    {
                        case ":!join":
                            SendData("JOIN", Text[4]);
                            //if the command is !join send the "JOIN" command to the server with the parameters set by the user
                            break;
                        case ":!say":
                            SendData("PRIVMSG", Text[2] + " " + Text[4]);
                            //if the command is !say, send a message to the chan (ex[2]) followed by the actual message (ex[4]).
                            break;
                        case ":!quit":
                            SendData("QUIT", Text[4]);
                            //if the command is quit, send the QUIT command to the server with a quit message
                            shouldRun = false;
                            //turn shouldRun to false - the server will stop sending us data so trying to read it will not work and result in an error. This stops the loop from running and we will close off the connections properly
                            break;
                    }
                }
            }
        }

        public void Dispose()
        {
            if (StreamRead != null)
                StreamRead.Close();
            if (StreamWrite != null)
                StreamWrite.Close();
            if (NetStream!= null)
                NetStream.Close();
            if (Socket_TcpClient != null)
                Socket_TcpClient.Close();
        }
    }
}

一番の問題は接続部分です。残りをテストするのに十分な距離がありません。サーバーのアドレスとポートは正しいはずですが、プログラムはここで停止し、何も起こりません。(このサイトの情報を使用しました: http://help.twitch.tv/customer/com/portal/articles/1302780-twitch-irc )

try
{
    Socket_TcpClient = new TcpClient(server, port);
}

誰かが私の問題の答えを知っていることを願っています。
