vb.net实现“快乐十分”

我想搞个“快乐十分”彩票的一种，就是1-21，每次随机产生5个数，可以21选2，21选3，21选4，21选5，比如21选2吧，就是你所选的两个数要是产生5个数中任意的两个，这样就是中奖了，否则不中，中一个数不算，算不中奖，嘿嘿，然后选3，选4，5都是这样，，大虾们，麻烦了

上午花了时间 来写出来了。但是感觉写得太复杂了。没有一点逻辑的感觉。很多地方都需要修改。自己都有点看不过去的想法了。但降低标准，功能还是基本上实现了。

里面的判断条件自己写的太那。。。。。。，得修改修改才行呀。

在这里做个记录，方便以后进行修改学习。

changeState(1)
ElseIf radio.Name = "RadioButton2" Then
changeState(2)
