用个骰子

课程的理解

　　现在对类的理解更深刻了一些，应该.......知道类图的画法，这次作业是通过先构思类图再写代码。

设计实现

　　业务类：

• Dice（滚轮的一个面）
• DiceVessel（滚轮，存储6个滚轮面）
• Award（单个奖品）
• AwardVessel（奖品池）

　　UI类：

• 界面1：Form1
• 界面2：Form1、Form2

小结

　　上次作业理解错老师的意思，这次经过仔细思考类图的构建，对类的理解更深刻了，这次在编写代码阶段轻松了很多，相比上次一边写一边思考要省事很多。但是构思上面还欠缺经验，有时候还需要后面想到了再添加进去。

　　这次在随机数的产生上面出现一个问题：因为三个类同时返回随机数的时间间隔太短，随机数又是以当前时间返回伪随机数的，所以变成每次三个数都相同。后面查了其他人的博客（比如CSDN之类的），重写了随机数的方法（添加种子数和使用Threed.Sleep（）方法）。
