我想用C#做一个基于TCP/IP
我想用C#做一个基于TCP/IP，定时发送数据（每隔1s），实时接受数据，怎么做，谢谢 --------------------编程问答-------------------- 关注!
--------------------编程问答--------------------
socket
--------------------编程问答--------------------
UP，如果是TCP的协议的话，就用TCPListener和TCPClient
如果是UDP的话，就用UDPClient
如果你想自由的控制的话，就直接用Socket。 --------------------编程问答-------------------- socket --------------------编程问答-------------------- socket通信 客户端 服务端 --------------------编程问答-------------------- socket tcp udp都行 --------------------编程问答--------------------
