C# 套接字 : Why does socket. LocalEndPoint 更改？

Question

执行后在UDP客户端中:

socket.SendTo(data, SendIP);

为什么 socket.LocalEndPoint 会改变？

Answer 1

如果您从未调用过 socket.Bind，那么在第一次传输时，UDP 堆栈会自动为您分配一个本地地址。

引自 MSDN:

If you are using a connectionless protocol, you do not need to establish a default remote host with the Connect method prior to calling SendTo. ... .You are also not required to call the Bind method, because the underlying service provider will assign the most appropriate local network address and port number.
