产生一个int数组，长度为100，并向其中随机插入1-100，并且不能重复(C#)

            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();
            }
