C#使用随机数模拟器来模拟世界杯排名(二)_斯内科的博客-CSDN博客

上一篇我们使用随机数匹配比赛的世界杯国家,

这一篇我们使用随机数以及胜率模拟器 决赛出 世界杯冠军、亚军。

我们在主界面 新增按钮【开始比赛 直到 决出冠军】和【刷新重新随机分配】

面板Panel:pnlWorldCup

按钮:【开始比赛 直到 决出冠军】btnStart

按钮:【刷新重新随机分配】btnRefresh

富文本控件RichTextBox:rtxtDisplay

窗体FormWorldCupRanking设计如图:

 更新CountryUtil.cs,增加SoccerGame方法,用于获取两个参赛世界杯国家胜利的一方。

CountryUtil源程序如下:
