(C#)TcpClient未连接到irc服务器(使用数字ip)

所以，我一直在尝试制作一个连接到本地irc服务器的bot。问题是，如果我用Irc irc = new Irc("192.168.1.2", 6667); irc.joinChannel("#test")这样的构造函数调用我创建的"Irc.cs"类，它就不会显示在Irc服务器通道上。问题是，我不认为它无法连接，因为如果我放置Irc irc = new Irc("192.168.1.11", 6667)（它不是服务器），它会抛出一个异常，但服务器不会。如果有人能帮忙，我会很高兴的：）这是"Irc.cs"的代码

        public IrcBot(String ip, int port, String nickName)
    {
        tcpClient = new TcpClient(ip, port);
        inputStream = new StreamReader(tcpClient.GetStream());
        outputStream = new StreamWriter(tcpClient.GetStream());
        outputStream.WriteLine("NICK " + nickName);
        outputStream.WriteLine("USER " + nickName + " 8 * : " + nickName);
        outputStream.Flush();
    }
        public void joinRoom(String channel)
    {
        this.channel = channel;
        outputStream.WriteLine("JOIN " + channel);
        outputStream.Flush();
    }

writer = new StreamWriter(stream) { NewLine = "'r'n" };
