我可以在differante端口从服务器中恢复数据TCP [英] haw can I recive data TCP from Server in differante ports
问题描述
你好
i我试图连接远程服务器如何向不同端口的客户端发送数据
port 1：11006
port 2：11003
port 3：11005
port 4：11000
这个TCP数据托盘保存在二进制文件中
但我有网络流问题
我可以添加多个网络流

端口已连接好但我不知道如何将蚀刻端口中的不同数据分开
我没有查看你的代码转储，因为你没有对它进行评论（顺便说一下，它没有正确格式化）。
这个想法是：你必须有TcpListener的单独实例，并且每个端口都有单独的TcpClient实例。此外，您应该更好地为每个端口实例使用两个单独的线程：一个侦听新连接，另一个根据您的应用程序层协议执行数据交换：从/向网络流读取/写入。在客户端，每个端口需要一个单独的线程。
有关其他细节，请查看我过去的答案：

Hello
i am trying to connect in the distant server how send data to clients in different ports
port 1 :11006
port 2 :11003
port 3 :11005
port 4 :11000
this TCP data t tray to save its in binary file
but I have problem with Network Stream
I can add more than one network stream

the port is connected OK but I don't know how a get the different data in etch port separated
I did not look through your code dump, because you did not comment on it (and it is not formatted properly, by the way).
The idea is: you have to have separate instances ofTcpListenerand separate instances ofTcpClientper port. Also, you should better use two separate threads per the instance of port: one listening for new connection, another one performing the data exchange according to your application-layer protocol: reading/writing from/to network stream. On client side, you would need one separate thread per port.
For some other detail, please see my past answers:

Multple clients from same port Number[^].
