由于需要在服务端和客户端持续通信，于是在网上找了好久的socket通信工具。刚开始想直接用.net自带的socket通信，后来担心不够稳定健壮，毕竟自己不专业。找来找去觉得supersocket还可以，但是说实话，他们的帮助文档写的真是太烂了，使用也不够简单易懂，折腾了一阵大致明白如何使用。
1，在nuget上引用supersocket.clientengine和supersocket.protobase
2，定义一个filter的类，protobase提供了5种预定义的方式，这里采用第二种，即定义数据头和尾的方式：
TerminatorReceiveFilterBeginEndMarkReceiveFilterFixedHeaderReceiveFilterFixedSizeReceiveFilterCountSpliterReceiveFilter

class MyBeginEndMarkReceiveFilter : BeginEndMarkReceiveFilter<StringPackageInfo>{ public MyBeginEndMarkReceiveFilter(string begin,string end) : base(Encoding.UTF8.GetBytes(begin), Encoding.UTF8.GetBytes(end)) { this.begin = begin; this.end = end; } string begin; string end; public override StringPackageInfo ResolvePackage(IBufferStream bufferStream) { //获取接收到的完整数据，包括头和尾 var body = bufferStream.ReadString((int)bufferStream.Length, Encoding.ASCII); //掐头去尾，只返回中间的数据 body = body.Remove(body.Length - end.Length, end.Length); body = body.Remove(0, begin.Length); return new StringPackageInfo("", body, new string[] { }); }} |
3，封装一个简单的类。初始化类的时候设置好ip，端口，数据头和尾，然后设置要发送的数据属性data，然后调用startcomm方法开始每秒发送一次请求数据到服务器，订阅接收数据的事件newReceived。如果有需要可以随时更换data的内容，或者调用stopcomm停止发送数据
