最近互联网彩票被国家叫停进行整改了，整改后互联网公司获取利润肯定会降低，但是不得不说中国的互联网彩票销售需要进行整改了，虽然对行业是阵痛，但是能够更好的规范彩票市场，对整个市场都会起到积极的作用。前段时间在做互联网彩票时也遇到了一些问题，特别是足彩任选九的复试组合算法。
足彩标注投注玩法：从14场比赛中任意选择9场比赛，每场比赛选择1种比赛结果为1注，每场比赛最多可选3种结果，单注最高奖金500万元！标准投注时可选择1～8场比赛结果作为胆码，其它比赛场次结果作为拖码进行胆拖投注，单注最高奖金500万元！
足彩标准投注是只从14场比赛中选9场比赛，而我们提交给第三方接口的必须是标准投注方式，也就是每次提交投注都是只能选择九场进行提交，但是在大部分的互联网彩票投注站都允许超过9场比赛的一个投注方式，这里就是各个互联网投注终端自己做的一个循环提交的处理了，所以这个需要一个自己组合算法，下面是该算法的代码，用C#代码实现：
这是足彩类型
