这篇文章主要为大家相许介绍了轻松实现微信抢红包的ASP.NET代码,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
群里都在玩抢红包,抢了再发,发了再抢,简直是无聊,程序员感兴趣是的如何实现,这里简单说说实现思路,附上dome,代码有点low,好在是实现了,具体内容如下
正文
100块发30个红包
50块发13个红包
1块发10个红包
发红包需要满足以下几个条件
1.总金额不变
2.每个红包都必须有钱
3.尽量的均匀点,不然抢红包没什么意思了
实现思路1.首先要确定最小单位,这里是精确到分,我这里以int类型进行计算,得出的结果也全是int类型
2.数据均匀,这里以 1
4.打乱顺序,细心的园友可能发现,红包是有顺序规律的,我们必须简单的写个function去打乱它.
