u3d局域网游戏网络（c# socket select 模型）——续

原文：http://www.cnblogs.com/saucerman/p/5555793.html

因为项目要加语音。语音数据都非常大。所以顺带就把之前写的网络模块一起测试了。

然后发现了一些bug，逐修。本来想在原文上面直接修改掉。但是恐怕已经看到的人拿去用了之后，再回头看也不一定能看明白，索性再写一文，将新文件直接放上来。

错误修改：

网络接收数据后，有一种情况没有处理完整，导致接收数据之后数据池的计数器没有向后偏移
网络数据处理后，当当前包仅剩1字节，下一个次数据进来的时候，需要2字节才能确认当前消息长度。增加了消息补齐机制。
增加了当网络数据拥堵的时候，直接断开当前链接。
MsgUnPack的GetHead函数获取消息id的时候使用了错误的函数，导致数据偏移不正确
MsgUnPack的UnPack(byte[] mBuff, ushort offset, ushort len)，由于总buff扩大，导致offset参数超过上限，改为int
消息事件增加了错误消息ID过滤

由于语音的需求，将原本的服务器段接受buff容量扩大一倍。增加了语音模块。

特别说下语音模块。

这是原文。

稍做修改。特别说一下这个语音模块在使用中容易遇到的问题。

如果声音太小，可能是你录音设备的侦听开得不够。
本地测试还好，放到网络上之后，因为代码里有处理，如果没有对象会创建对象并且添加必要组件。原文在创建的时候比特率是手动填写的。导致我客户端一个比特率，服务器一个比特率。然后客户端听着一切正常，传给服务器就错了。后来查了一天，排查各个代码段之后才找到这个原因。

以下是代码：
