Question

我正在尝试制作一个程序，该程序生成从1到49的6个唯一数字，奖金数字和7位额外数字，我想检查这6位数字是否与当前乐透号码匹配或奖金号码匹配。我还想检查7个额外数字中的任何一个是否匹配。我不确定如何将每个数组中的数字相互比较。

任何帮助将不胜感激

static void PLayLotto649()
{
    int[] currentNumbers = ChangeLotto49Numbers();
    int[] extraNumbers = ChangeLottoExtraNumbers();
    int[] userLottoNumbers = StartingNumbers();
    int[] userExtraNumbers = AutoGenrateExtraNumbers();

    Console.WriteLine($"\nThe current Lotto 6/49 number are: {string.Join(",",currentNumbers)}" );
    Console.WriteLine($"\nThe current Extra number is:{string.Join(",", extraNumbers)}"); 

    Console.WriteLine($"\nYour 6/49 number is: { string.Join(",", userLottoNumbers)}");
    Console.WriteLine($"\nYour lotto Extra number is: { string.Join(",", userExtraNumbes)}");
}

static int[] StartingNumbers()
{
    int temp;
    int[] lotto = new int[7];

    Random rand = new Random();

    for (int i = 0; i < 7; i++)
    {
        temp = rand.Next(1, 50);
        lotto[i] = temp;
    }

    return lotto;
}

static int[] ChangeLottoExtraNumbers()
{
    int temp;
    int[] extra = new int[7];

    Random rand = new Random();

    for (int i = 0; i < 7; i++)
    {
        temp = rand.Next(0, 7);
        extra[i] = temp;
    }
    Console.Write($"the new extra number is: ");
    for (int i = 0; i < 7; i++)
    {
        Console.Write(extra[i] + " ");
    }
    return extra;
}

static int[] AutoGenrateExtraNumbers()
{
    int temp;
    int[] autoExtra = new int[7];

    Random rand = new Random();

    for (int i = 0; i < 7; i++)
    {
        temp = rand.Next(0, 7);
        autoExtra[i] = temp;
    }
    Console.Write($"the new extra number is: ");
    for (int i = 0; i < 7; i++)
    {
        Console.Write(autoExtra[i] + " ");
    }
    return autoExtra;
}

static int[] ChangeLotto49Numbers()
{
    int temp;
    int[] lotto49 = new int[6];

    Random rand = new Random();

    for (int i = 0; i < 6; i++)
    {
        temp = rand.Next(1, 49);
        lotto49[i] = temp;
    }
    Console.Write($"the new lotto Max winning numbers are: ");

    for (int i = 0; i < 6; i++)
    {
        Console.Write(lotto49[i] + " ");
    }

    return lotto49;
}

尝试这样的事情：

static bool IsEqualTo(this int[] source, int[] target) {
    if (source == null && target != null || 
        source != null && target == null || 
        source?.Length ?? 0 != target?.Length ?? 0) {
       return false;
    }

    if (source == null && target == null) {
       return true;
    }

    for (var i = 0; i < source.Length; i++) {
     if (source[i] != target[i]) {
       return false;
      }
    }

    return true;
}

然后使用：

     int[] currentNumbers = ChangeLotto49Numbers();
     int[] extraNumbers = ChangeLottoExtraNumbers();
     if (currentNumbers.IsEqualTo(extraNumbers)) { // do something 
     }
