C# 一个长度为100的int数组,插入1-100的随机数,不能重复,如何写

int[] intArr = new int[100];
ArrayList myList = new ArrayList();
Random rnd = new Random();
while (myList.Count < 100)
{
　　int num = rnd.Next(1, 101);
　　if (!myList.Contains(num))
　　myList.Add(num);
}
for (int i = 0; i <100; i++)
{
　　intArr[i] = (int)myList[i];
　　Console.Write("{0} ", intArr[i]);
　　Console.WriteLine();
