Question

所以，我试图做一些检查是否能自动赢得彩票。

我玩这个游戏有25个号码，你可以选择15个。

如果你打了15个数字，你就赢了！（它不需要在序列中）

我列出了所有名为：＆＃39; TodosJogos＆＃39; 我的赌博叫做：＆＃39; Jogado＆＃39;

现在，我这样做:(我觉得这很可怕）

 private void VerificaVitoria(Jogo Jogado, string TipoJogo)
        {
            bool Ganhou;
            List<Jogo> LstClassificadas = new List<Jogo>();

            LstClassificadas = TodosJogos.Where(x => x.N1 == Jogado.N1 ||
                x.N1 == Jogado.N2 ||
                x.N1 == Jogado.N3 ||
                x.N1 == Jogado.N4 ||
                x.N1 == Jogado.N5 ||
                x.N1 == Jogado.N6 ||
                x.N1 == Jogado.N7 ||
                x.N1 == Jogado.N8 ||
                x.N1 == Jogado.N9 ||
                x.N1 == Jogado.N10 ||
                x.N1 == Jogado.N11 ||
                x.N1 == Jogado.N12 ||
                x.N1 == Jogado.N13 ||
                x.N1 == Jogado.N14 ||
                x.N1 == Jogado.N15).ToList<Jogo>();

            LstClassificadas = LstClassificadas.Where(x => x.N2 == Jogado.N1 ||
               x.N2 == Jogado.N2 ||
               x.N2 == Jogado.N3 ||
               x.N2 == Jogado.N4 ||
               x.N2 == Jogado.N5 ||
               x.N2 == Jogado.N6 ||
               x.N2 == Jogado.N7 ||
               x.N2 == Jogado.N8 ||
               x.N2 == Jogado.N9 ||
               x.N2 == Jogado.N10 ||
               x.N2 == Jogado.N11 ||
               x.N2 == Jogado.N12 ||
               x.N2 == Jogado.N13 ||
               x.N2 == Jogado.N14 ||
               x.N2 == Jogado.N15).ToList<Jogo>();

            LstClassificadas = LstClassificadas.Where(x => x.N3 == Jogado.N1 ||
                 x.N3 == Jogado.N2 ||
                 x.N3 == Jogado.N3 ||
                 x.N3 == Jogado.N4 ||
                 x.N3 == Jogado.N5 ||
                 x.N3 == Jogado.N6 ||
                 x.N3 == Jogado.N7 ||
                 x.N3 == Jogado.N8 ||
                 x.N3 == Jogado.N9 ||
                 x.N3 == Jogado.N10 ||
                 x.N3 == Jogado.N11 ||
                 x.N3 == Jogado.N12 ||
                 x.N3 == Jogado.N13 ||
                 x.N3 == Jogado.N14 ||
                 x.N3 == Jogado.N15).ToList<Jogo>();

            //.....

            Ganhou = LstClassificadas.Count > 0 ? true : false;


            if (Ganhou)
            {
                MessageBox.Show("You won in the game: " + TipoJogo);
            }

        }

它与此查询类似：

select * from jogos
where n1 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n2 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n3 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n4 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n5 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n6 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n7 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n8 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n9 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n10 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n11 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n12 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n13 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n14 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)
and n15 in(8,18,16,7,5,20,9,6,10,17,22,3,14,21,15)

有没有更好的方法呢？

Answer 1

解决问题的两种方法。

将一个获胜组合表示为一组十五个整数：

HashSet<int>

你有一系列中奖游戏：

IEnumerable<HashSet<int>>

和特定的HashSet<int>。您希望知道特定集合是否与任何获胜集合完全匹配。

方法一

static bool DidIWin(IEnumerable<HashSet<int>> winningNumbers, HashSet<int> myNumbers)
{
    return winningNumbers
      .Where(winningNumber => myNumbers.SetEquals(winningNumber))
      .Any();
}

甚至

static bool DidIWin(IEnumerable<HashSet<int>> winningNumbers, HashSet<int> myNumbers)
{
    return winningNumbers
      .Any(winningNumber => myNumbers.SetEquals(winningNumber));
}

方法二

static bool DidIWin(IEnumerable<HashSet<int>> winningNumbers, HashSet<int> myNumbers)
{
    return false;
}

方法二更快。但是，它在每三百万个中奖号码中平均给出一次不正确的结果。这表明，有时候你可以通过愿意接受一点点不准确来获得巨大的成绩。

Answer 2

从您的SQL查询来看，我认为这就是您想要的：

var lotteryNumbers = new int[] { ... };
var results =
    from j in jogos
    where lotteryNumbers.Contains(j.n1) &&
          lotteryNumbers.Contains(j.n2) &&
          lotteryNumbers.Contains(j.n3) &&
          lotteryNumbers.Contains(j.n4) &&
          lotteryNumbers.Contains(j.n5) &&
          lotteryNumbers.Contains(j.n6) &&
          lotteryNumbers.Contains(j.n7) &&
          lotteryNumbers.Contains(j.n8) &&
          lotteryNumbers.Contains(j.n9) &&
          lotteryNumbers.Contains(j.n10) &&
          lotteryNumbers.Contains(j.n11) &&
          lotteryNumbers.Contains(j.n12) &&
          lotteryNumbers.Contains(j.n13) &&
          lotteryNumbers.Contains(j.n14) &&
          lotteryNumbers.Contains(j.n15)
    select j;

或者用流利的语法

var results =
    jogos.Where(j =>
          lotteryNumbers.Contains(j.n1) &&
          lotteryNumbers.Contains(j.n2) &&
          lotteryNumbers.Contains(j.n3) &&
          lotteryNumbers.Contains(j.n4) &&
          lotteryNumbers.Contains(j.n5) &&
          lotteryNumbers.Contains(j.n6) &&
          lotteryNumbers.Contains(j.n7) &&
          lotteryNumbers.Contains(j.n8) &&
          lotteryNumbers.Contains(j.n9) &&
          lotteryNumbers.Contains(j.n10) &&
          lotteryNumbers.Contains(j.n11) &&
          lotteryNumbers.Contains(j.n12) &&
          lotteryNumbers.Contains(j.n13) &&
          lotteryNumbers.Contains(j.n14) &&
          lotteryNumbers.Contains(j.n15));

虽然这假设您在lotteryNumbers或j.n1 .. j.n15中没有重复项。否则你可能会得到意想不到的结果。
