ASP.NET实现微信抢红包代码实例

100块发30个红包

50块发13个红包

1块发10个红包

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

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<n<(剩余金额/剩余红包数)*2,这里防止一个红包抢走大量的钱,这里需要写个递归,去检查数据值是否过大,50元发13个红包的第3图,就是因为没有检查数据,导致钱不平均,这个可以根据自己的玩法去设置.3.余数处理,当数据平均给20个红包,肯定跟总金额有所偏差,这时候我们就要多退少补,如果大于总金额,让红包金额多的去减少(总金额/总人数),如果还有剩余,就让第二多的去减少,直到补完这个空缺为止,反之亦然.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.
