问题描述

Hi Code项目，

我正在编写一个连接到IRC频道并读出消息的简单程序。请解释一下我该如何做到这一点？

我可以编写一个连接到主机但不能连接到Web服务器或IRC服务器的程序o你看到了问题。 />
先谢谢。

Hi Code project,

I am coding a simple program which connects to a IRC channel and reads out messages. Please explain how i can do that ?

I can code a program which connects to a host but not to web servers or IRC servers o you see the problem.
Thanks in advance.
