确定基于0的阵列上的模数

Question

我有一个数组,索引从0开始.我试图确定如何在数组中找到特定的项目.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

我只想要2,6,10,14.如果它不是0索引数组,我可以在索引上做模数%3并得到我想要的但我无法弄清楚如何做到这一点.

    string[] arr = new string[16];
    arr[0] = "data";
    arr[1] = "data";
    arr[2] = "data";
    arr[3] = "data";
    arr[4] = "data";
    arr[5] = "data";
    arr[6] = "data";
    arr[7] = "data";
    arr[8] = "data";
    arr[9] = "data";
    arr[10] = "data";
    arr[11] = "data";
    arr[12] = "data";
    arr[13] = "data";
    arr[14] = "data";
    arr[15] = "data";
    for (int i = 0; i < arr.Length; ++i)
    {
        if (i % 3 == 0)
        {
            Console.WriteLine(arr[i]);
            Console.ReadLine();
        }
    }
    Console.ReadLine();

这当然对我不起作用,我试过操纵'我',但我今天还没有喝足够的咖啡才能让它发挥作用.

Answer 1

它看起来像你想要的

if(i % 4 == 2)
