UdpClient，接收（）右后发送（）不起作用？ [英] UdpClient, Receive() right after Send() does not work?

问题描述

考虑下面的代码：

client.Send(data, data.Length, endpoint);
byte[] response = client.Receive(ref endpoint);

虽然，根据的是Wireshark（网络嗅探器），远程主机并用数据回答，
中的应用这里只是等待数据永远...它没有收到因某种原因远程主机的答案。

While, according to WireShark (network sniffer), the remote host does reply with data, the application here just waits for data forever... it does not receive the answer from the remote host for some reason.

任何想法？

推荐答案

您可能希望创建了两个UdpClients：一个是听，一个用于发送

You probably want to setup two UdpClients: one for listening, one for sending.

对于接收UdpClient，需要使用带有端口的构造。

For the receiving UdpClient, use the constructor that takes a port.
