基本按这个代码来的，小有改动。运行结果达到预期，但是发现两个问题，一个是CPU占用率会一直上升到100%，二是内存一直在涨。
第一个问题，我加了Thread.Sleep(1)解决问题。第二个问题我认为是出在AcceptConnection里，因为客户端会每隔1分钟都给我发个连接，我的服务器程序没有判断功能，对重复的连接也进行操作了，致使在没有新客户的情况下也新开线程。事实也是如此，通过任务管理器也可以看出我这个程序的线程数一直在增加。我在AcceptTcpClientCallback里做了个判断，对于重复的IP和端口直接返回，但是我不知道AcceptConnection里的callback如何释放掉。
不知我的理解对否，求解答。
