这个机器人对于我的世界有一个错误

Question

我为Minecraft 1.12编写了一个机器人的代码，但它不起作用，你能帮助我吗？

这是代码：

  

    private void button1_Click(object sender, EventArgs e)
    {
        TcpClient client = new TcpClient(IP.Text, Int32.Parse(PORT.Text));
        NetworkStream stream = client.GetStream();
        stream.Flush();
        BinaryWriter wr = new BinaryWriter(stream);

        byte PacketID = 0x35;
        byte ProtocolVersion = 35;
        string Username = "Name";
        Username.PadRight(64, ' ');
        string VerificationKey = password.Text;
        VerificationKey.PadRight(64, ' ');

        wr.Write(PacketID);
        wr.Write(ProtocolVersion);
        wr.Write(Username);
        wr.Write(VerificationKey);

        BinaryReader rea = new BinaryReader(stream);
        richTextBox1.Text = rea.Read().ToString();
    }
}
}
