DatagramSocket 事件 MessageReceived 不触发 [英] DatagramSocket event MessageReceived dosen't trigger

问题描述

我有一个基于 System.Net.Sockets UdpClient 的控制台 Udp 服务器，我从中发送 Udp 数据包到我的 Windows Phone 8.1 的 Ip.

手机客户端使用的是Windows.Networking.Sockets DatagramSocket，我的问题是没有发生MessageReceived事件.

解决方案

我花了很长时间才找到解决方案，因为它非常愚蠢:DatagramSocket 只在发送了一些东西后才开始接收.(至少对于广播消息.)

I have a Console Udp Server based on the System.Net.Sockets UdpClient from which I'm sending Udp Packets to the Ip of my Windows Phone 8.1.

The client on the phone uses Windows.Networking.Sockets DatagramSocket, my problem is that the event MessageReceived dosen't happen.

解决方案

Took me ages to find the solution since it's pretty dumb: The DatagramSocket only starts to receive after it has sent something. (At least for broadcast messages.)
