[请进] 用C#发送数据包,给一个实例马上结分

[RexZheng]

怎么指定一个本地端口来连接服务器，并向服务器发送数据包!

[hyj_828]

tcp/udp
socket
都可以實現.

[RexZheng]

谢谢楼上的,我知道可以用tcpclient,但是在指定本地端口这里遇到困难了.

详细点说可吗?最好能给一个实例

[RexZheng]

高手都那去了?

帮帮忙

我给一个发送文件的例子给你，你给出邮箱

刚发了，我把客户端和服务器端都封装成类了，还有部分东西还没有写好，是“停止发送或接受”

[RexZheng]

谢谢收到了,正在看

再问一下,怎么指定本地端口?

// Close everything.
