我的数组中的随机数由最后一个randomed填充

Question

我创建了一个程序,用户可以在其中选择有多少数字的数组,这个数组应该有随机值.嗯,事实并非如此.要在每次尝试为每个数组参数签名后检查,我会使console.writeline显示随机分配的编号.最后整个数组由最后一个randomed这个方法填充:

static void Main(string[] args)
{

    Console.WriteLine("Set the number of arguments in mineArray:");
    string argumentsNumber = Console.ReadLine();
    int argumentsNumberInt = Convert.ToInt32(argumentsNumber);
    int[] mineArray = new int[argumentsNumberInt];
    Random rand = new Random();

    //set up values to each index of array
    foreach (int i in mineArray)
    {
        mineArray[] = rand.Next(1, 10);
        Console.WriteLine(i + " " + mineArray[i]);
    }
    string a = "asd";

    foreach (int k in mineArray)
    {
        if (mineArray[k] % 3 == 0 || mineArray[k] % 5 == 0)
        {
            if (mineArray[k] % 3 == 0 && mineArray[k] % 5 == 0)
            {
                a = "Able to divide by 3 and 5";
            }
            else
            {
                if (mineArray[k] % 3 == 0) { a = "Able to divide only by 3"; }
                if (mineArray[k] % 5 == 0) { a = "Able to divide only by 5"; }
            }

        }
        else
        {
            a = "Number unable to divide";
        }
        Console.WriteLine(mineArray[k] + " " + a);
    }

我假设你这样做mineArray[i] = rand.Next(1, 10);,否则这将无法编译(你的代码遗漏了i).

问题出在你的foreach循环中:

int[] mineArray = new int[argumentsNumberInt];
Random rand = new Random();

//set up values to each index of array
foreach (int i in mineArray)

foreach每次分配随机变量时,这将通过一个填充零的数组运行mineArray [0].

用途for:

for (int i = 0; i < argumentsNumberInt; i++)
