我正在用C#制作一个Windows窗体应用程序，我有一个for循环，它打印了20个元素，其中包含一个0到500之间的随机数。使用这些数字，我需要计算下一个数字。我想使用变量“numbers[i]”来打印它，但这不起作用，程序选择了新的随机数。下面是一些代码：

private void Form1_Load(object sender, EventArgs e)
        {
            CultureInfo ci = new CultureInfo("en-US");
            Thread.CurrentThread.CurrentUICulture = ci;
            Thread.CurrentThread.CurrentCulture = ci;

            int[] numbers = new int[numberOfItems];

            Random random = new Random();
            double total = 0;

            var text = "";
            for (int i = 0; i < numbers.Length; i++)
            {
                numbers[i] = random.Next(501);
                
                beforeLoop.Text += $"Element {i} = {numbers[i]} \n";
               
        

                total += numbers[i];

            }
       
        

        }

        private void compare_Click(object sender, EventArgs e)
        {
            int count = 0;
            count++;
            if (count ==1 ) // knop is maar 1 keer drukbaar
            {
                compare.Enabled = false;
            }

            int[] numbers = new int[numberOfItems];

            Random random = new Random();
            double total = 0;

            for (int i = 0; i < numbers.Length; i++)
            {
                numbers[i] = random.Next(501);
              
                int numberBigger = numbers[i] + 10;
                int numberSmaller = numbers[i] - 5;
                total += numbers[i];
                int number = int.Parse(numberBox.Text);

                if (number > numbers[i])

                {
                    printLabel.Text += $"Element {i} = {numberBigger}\n";
                }
                else
                {
                    printLabel.Text += $"Element {i} = {numberSmaller}\n";
                }

            }
