Question

我只是想要一些代码方面的帮助。
我将其设置如下：

public partial class frmAdditionTutor : Form
{
    public int I = 0;
    public frmAdditionTutor()
    {
        InitializeComponent();
        Random rand = new Random();
        int NumberOne = rand.Next(500) + 100;
        int NumberTwo = rand.Next(500) + 100;
        lblEquation.Text = NumberOne.ToString() + " + " + NumberTwo.ToString() + "= ?";
    }

    private void btnSolve_Click(object sender, EventArgs e)
    {
        Random rand = new Random();
        int NumberOne = rand.Next(500) + 100;
        int NumberTwo = rand.Next(500) + 100;
        int TotalAmount = NumberOne + NumberTwo;
        int UserInputs = Convert.ToInt32(txtInput.Text);

        if ((NumberOne + NumberTwo) == UserInputs)
        {
            lblRightorWrong.Text = "Correct!";
            I++;
            txtAmountCorrect.Text = I.ToString();
        }
        else
        {
            lblRightorWrong.Text = "Incorrect!";
            I++;
            txtQuestionCount.Text = I.ToString();
        }
    }
}

启动该程序时，会给用户一个方程式来解决。
当他们输入问题时，代码将检查其是否正确。如果答案正确，我希望它在Label中显示正确！，然后将+1添加到我的AmountCorrect TextBox中。 />

问题在于，无论用户是否正确输入代码，代码都认为它是错误的并且不会添加到计数器上。

我希望我的代码随机显示不同的变量，以使该人获得正确的答案。

在代码中，您在单击求解按钮的同时创建了新的NumberOne和NumberTwo。如果要再次创建随机问题，请在计算后再执行一次。您还可以使用一种方法来使代码可重复使用。

 public partial class frmAdditionTutor : Form
    {
        public int CorrectAnswerCount = 0;
        public int IncorrectAnswerCount = 0;
        int NumberOne = 0;
        int NumberTwo = 0;

        public Form1()
        {
            InitializeComponent();
            CreateRandomQuestion();
        }

        private void btnSolve_Click(object sender, EventArgs e)
        {
            int TotalAmount = NumberOne + NumberTwo;
            int UserInputs = Convert.ToInt32(txtInput.Text);

            if (TotalAmount == UserInputs)
            {
                lblRightorWrong.Text = "Correct!";
                CorrectAnswerCount++;
                txtAmountCorrect.Text = CorrectAnswerCount.ToString();
            }
            else
            {
                lblRightorWrong.Text = "Incorrect!";
                IncorrectAnswerCount++;
                txtAmountWrong.Text = IncorrectAnswerCount.ToString();
            }

            CreateRandomQuestion();
        }

        public void CreateRandomQuestion()
        {
            Random rand = new Random();
            NumberOne = rand.Next(500) + 100;
            NumberTwo = rand.Next(500) + 100;
            lblEquation.Text = NumberOne.ToString() + " + " + NumberTwo.ToString() + "= ?";
            txtInput.Clear();
        }
    }

为什么答案正确，为什么我的代码输出“不正确”？
