这个游戏是我有史以来（寒）编写的第一个比较完整的程序，而这一次，经过两天的学习和反复摸索，终于使用C#将其重写；程序中有很多不必要的结构，实际上基本上把我知道的内容都刻意的作了尝试和使用，包括设计模式中的简单工厂，基本的数据类型及转换、控制语句、面向对象的类（构造、方法和属性）、继承（重载、抽象、虚成员和多态）、接口、代理、事件、异常等等。-this game I ever (cold) preparation of a more complete procedure, and this time, after two days of study and repeated exploration, and finally the use of C# to rewrite; Procedures for a lot of unnecessary structures, in fact I know that basically the contents were deliberately try try and use, including the design of a simple model plant, the basic data types and conversion, control statements, object-oriented category (structures, methods and properties), inheritance (heavy, abstract, virtual members and polymorphic), interface, agent, events, etc. abnormal.

说明：  以上是本人根据网络上查找到资料和代码学习借鉴有自己加入了一些部分的——PID控制实现代码(Above all, I find information and learn code from the network. I have added some parts of the implementation code of PID control.)
