Tcp聊天室, TcpListener 监听两个IP

[liulangonline]

局域网有两个网关,一个是192.168.0.1 , 一个是192.168.0.2
有一台服务器,这台服务器有两张网卡,一张网卡的IP是192.168.0.101 , 网关是192.168.0.1
另一张网卡的IP是192.168.0.102 , 网关是192.168.0.2

Tcp聊天室的服务端放就放在这台服务器上.

问题来了,怎样才能使得局域网中不同网关的客户端进行通信?

TcpListener能否监听两个IP?

具体怎样实现?

当然可以侦听两个IP了，多少个IP都可以侦听，关键看你代码如何写。

但问题是怎样实现啊,光说"当然可以"对我是没用的,因为我还是不知怎样侦听,能写上几行代码吗?

给你一个能运行的代码。。。其中就包含了局域网通讯

kkun_3yue3 的代码也是侦听一个IP吧?

[liulangonline]

有没有其它解决方法啊?
