根据MSDN
:
TcpListener类提供了在阻塞同步模式下侦听和接受传入连接请求的简单方法。
我的团队负责人要求使用TcpListener
发送数据。使用receive
对send
以及TCPListerner
数据有什么办法或可行吗?
我已经知道如何使用TCPListener
接收数据,不知道如何使用相同的方式发送数据。我知道TCPClient
可用于发送数据,但我们的团队负责人希望使用TCPListerner
来完成此操作。
请告诉我您的意见,并通过一些示例代码告诉我是否可行。
答案 0 :(得分:5)
不是真的。 TcpListener的目的是接受 新的连接。
但是,从TcpListener获得的流对象(一旦建立连接)可用于读写。
