利用C#中的随机数对象生成20个(10,100)之间的整数,输出这20个数中的最大值和最小值

Random rd = new Random();
int[] arr = new int[20];
int max = -1;
int min = -1;
for (int i = 0; i < 20; i++)
{
arr[i] = rd.Next(10,100);
max = max > arr[i] max :arr[i];
min = min < arr[i] min :arr[i];
}
Console.WriteLine("min=" + min);
Console.WriteLine("max=" + max);

for (int i = 0; i < 20; i++)
{
if (i == 0 || i == 19)
{
Console.WriteLine(nums[i]);
}
}

for (int i = 0; i < 20; i++)
{

Console.WriteLine(nums[i]);

}
