Windows Phone 7 网络编程之使用Socket(芒果更新)
芒果更新的Windows Phone 7.1版本的API提供了Socket编程的接口,这给Windows Phone 7的网络开发又添加了一把利器,对于Windows Phone 7上的聊天软件开发是一件非常happy的事情。下面用一个小例子来演示一下Windows Phone 7上的Socket编程。用Windows Phone 7上的客户端程序作为Socket客户端,Windows控制台程序作为服务器端,ip取你电脑本机的ip,端口号用8888,实现了Windows Phone 7客户端向服务器端发送消息和接收消息的功能。
先来看看演示的效果
(1) Windows Phone 7客户端客户端的实现。
