如何将随机数存储到数组中,但前提是数组中没有重复数?我下面的代码仍然输入重复的数字。
Random rand = new Random();
int[] lotto = new int [6];
for (int i = 0; i < lotto.Length; i++)
{
int temp = rand.Next(1, 10);
while (!(lotto.Contains(temp)))//While my lotto array doesn't contain a duplicate
{
lotto[i] = rand.Next(1, 10);//Add a new number into the array
}
Console.WriteLine(lotto[i]+1);
}
最佳答案
试试这个:
Random rand = new Random();
int[] lotto = new int[6];
for (int i = 0; i < lotto.Length; i++)
{
int temp = rand.Next(1, 10);
// Loop until array doesn't contain temp
while (lotto.Contains(temp))
{
temp = rand.Next(1, 10);
}
lotto[i] = temp;
Console.WriteLine(lotto[i] + 1);
}
这样,代码会一直生成一个数字,直到找到一个不在数组中的数字,然后分配它并继续前进。
有很多方法可以“随机”排列数组,但是希望这可以解决您的代码问题。
