Visual Studio的C＃彩票循環程序

Question

我目前正在試圖弄清楚如何在Visual Studio中創建一個程序，該程序與文本框中給出的3個數字1-9相匹配，該文本框中具有在列表框中3個隨機生成的數字。 我在弄清楚如何編寫WHILE循環語句時遇到麻煩，該語句允許我的列表框一次隨機生成3個數字，如果沒有匹配項則繼續，但是如果有匹配項則中斷，最多嘗試1000次。 我對如何執行此操作有些迷茫。 謝謝您的幫助。

        private void LuckyButton_Click(object sender, EventArgs e)
    {
        Random RandomNumber = new Random();
        string newLine = Environment.NewLine;
        int Winning1 = 0;
        int Winning2 = 0;
        int Winning3 = 0;
        int numbers = RandomNumber.Next(10);

        int.TryParse(WinningNumber1.Text, out Winning1);
        int.TryParse(WinningNumber2.Text, out Winning2);
        int.TryParse(WinningNumber3.Text, out Winning3);


        if (Winning1 <= 0 || Winning2 <= 0 || Winning3 <= 0)
        {
            MessageBox.Show("Enter a number!");
            return;
        }

        while (numbers <= 1000)
        {
            numbers = RandomNumber.Next(10);
        }

    }

看看這是否對您有幫助：

 private void LuckyButton_Click(object sender, EventArgs e)
    {
        Random RandomNumberGenerator = new Random();
        string newLine = Environment.NewLine;
        int Winning1 = 0;
        int Winning2 = 0;
        int Winning3 = 0;
        int randomNumber = RandomNumberGenerator.Next(10);
        int counter = 0;
        int winnerId = 0;


        int.TryParse(WinningNumber1.Text, out Winning1);
        int.TryParse(WinningNumber2.Text, out Winning2);
        int.TryParse(WinningNumber3.Text, out Winning3);


        if (Winning1 <= 0 || Winning2 <= 0 || Winning3 <= 0 ||
            Winning1 > 10 || Winning2 > 10 || Winning3 > 10)
        {
            MessageBox.Show("Invalid Number!");
            return;
        }

        while (counter < 1000)
        {
            if (Winning1 == randomNumber)
            {
                winnerId = 1;
                break;
            }
            else if (Winning2 == randomNumber)
            {
                winnerId = 2;
                break;
            }
            else if (Winning3 == randomNumber)
            {
                winnerId = 3;
                break;
            }
            randomNumber = RandomNumberGenerator.Next(10);
            counter++;
        }

        if(winnerId != 0)
        {
            MessageBox.Show("Number " + winnerId + " wins!");
        }
        else
        {
            MessageBox.Show("no one wins!");
        }
    }
