生成新的随机数

每次我点击按钮，应该产生一个新的随机数，数字只是保持不变。我怎么能有相同的变量，但新的数字onclick?

static Random random = new Random();
static int randomNumber1 = random.Next(0, 100);
static int randomNumber2 = random.Next(0, 100);
num1Label.Text = randomNumber1.ToString();
num2Label.Text = randomNumber2.ToString();
protected void submitAnswerButton_Click(object sender, EventArgs e)
{
    answerStatus.Visible = true;
    int counter = 0;
    int answer = randomNumber1 + randomNumber2;
    if (mathAnswerTextBox.Text == answer.ToString())
    {
        answerStatus.Text = "Correct!";
        randomNumber1 = random.Next(2, 22);
        randomNumber2 = random.Next(2, 222);
        num1Label.Visible = true;
        num2Label.Visible = true;
    }

生成新的随机数

 protected void submitAnswerButton_Click(object sender, EventArgs e)
    {
        answerStatus.Visible = true;
        int counter = 0;
        int answer = randomNumber1 + randomNumber2;
        if (mathAnswerTextBox.Text == answer.ToString())
        {
            answerStatus.Text = "Correct!";
            randomNumber1 = random.Next(2, 22);
            randomNumber2 = random.Next(2, 222);
             num1Label.Text = Convert.ToString(randomNumber1);//add this line 
             num2Label.Text = Convert.ToString(randomNumber2); //and this line
            num1Label.Visible = true;
            num2Label.Visible = true;
        }

randomNumber1 = random.Next(2, 22);
randomNumber2 = random.Next(2, 222);
num1Label.Visible = true;
num2Label.Visible = true;

我看不出你在哪里把这两个新的随机数放入某种控制中。你使控件可见，但这并没有神奇地用新值填充它们。

如果不设置这些值，就会生成新的数字，但是用户永远不会看到它们。

您需要将num1Label控件的文本属性更改为randomNumber1的字符串值。第二个控件和数字也是如此。
