如何在C#/ Win32中编写和发送文本到mIRC？

using System;
using System.Net.Sockets;
using System.Text;

namespace MircChat
{
    class Program
    {
        static void Main(string[] args)
        {
            string server = "irc.example.com";
            int port = 6667;
            string nick = "mybot";
            string channel = "#mychannel";

            TcpClient client = new TcpClient(server, port);
            NetworkStream stream = client.GetStream();

            // Send NICK command
            SendMessage(stream, $"NICK {nick}");

            // Send USER command
            SendMessage(stream, $"USER {nick} 0 * :{nick}");

            // Join channel
            SendMessage(stream, $"JOIN {channel}");

            // Send message to channel
            SendMessage(stream, $"PRIVMSG {channel} :Hello, world!");

            // Close connection
            SendMessage(stream, "QUIT");
            client.Close();
        }

        static void SendMessage(NetworkStream stream, string message)
        {
            byte[] buffer = Encoding.UTF8.GetBytes(message + "\r\n");
            stream.Write(buffer, 0, buffer.Length);
        }
    }
}
