關於足彩任選九的組合算法

      最近互聯網彩票被國家叫停進行整改了，整改後互聯網公司獲取利潤確定會下降，可是不得不說中國的互聯網彩票銷售須要進行整改了，雖然對行業是陣痛，可是可以更好的規範彩票市場，對整個市場都會起到積極的做用。前段時間在作互聯網彩票時也遇到了一些問題，特別是足彩任選九的複試組合算法。

     足彩標註投注玩法：從14場比賽中任意選擇9場比賽，每場比賽選擇1種比賽結果爲1注，每場比賽最多可選3種結果，單注最高獎金500萬元！標準投注時可選擇1～8場比賽結果做爲膽碼，其它比賽場次結果做爲拖碼進行膽拖投注，單注最高獎金500萬元！ 

     足彩標準投注是隻從14場比賽中選9場比賽，而咱們提交給第三方接口的必須是標準投注方式，也就是每次提交投注都是隻能選擇九場進行提交，可是在大部分的互聯網彩票投注站都容許超過9場比賽的一個投注方式，這裏就是各個互聯網投注終端本身作的一個循環提交的處理了，因此這個須要一個本身組合算法，下面是該算法的代碼，用C#代碼實現：

    這是足彩類型

    返回一個字典集合，字典的key爲9場比賽的一個組合，而value爲這9場比賽有多長中組合方式，由於一場比賽能夠選擇三種比賽結果，因此須要知道每一種標準投注有多少注，再把字典中全部的value值求和就能知道該複試一共選擇了多少注，須要多少錢，可以再未提交以前知道須要的投注注數和總金額。最後循環調用投注接口把投注結果提交上去。

     爲了實現功能而作的，若是有更好的組合公式的請提出建議，謝謝！
