C# 比较两个数组，同时计算正确答案和错误答案的数量

我编写了一个程序，用户在其中玩游戏并猜测答案。 除了我的数组外，其他一切都很好，这个程序有两个数组，第一个是usersAnswers，它包含用户的选择，第二个是decompetimearray，它包含正确的答案。我写了一个方法，程序将比较两个数组，计算用户得到正确和错误答案的数量，并将它们的值放在两个单独的标签中。该程序运行良好，但它总是给我0为正确和不正确的标签，如果你能帮助我解决这个小问题，并使程序正确计算答案，我将不胜感激。这是我的密码：

public void usersAnswers()
    {


        userAnswers[0] = newspaperLbl.Text;
        userAnswers[1] = aluminumCanLbl.Text;
        userAnswers[2] = glassBottleLbl.Text;
        userAnswers[3] = plasticbagLbl.Text;
        userAnswers[4] = cupLbl.Text;
    }

    public void correctAnswers()
    {

        decompTimeArray[0] = "6 Weeks";
        decompTimeArray[1] = "10-20 Years";
        decompTimeArray[2] = "80-200 Years";
        decompTimeArray[3] = "1,000,000 Years";
        decompTimeArray[4] = "Never";
    }

    public void compareArrays()
    {
        bool arraysEqual = true;
        int index;
        if (userAnswers.Length != decompTimeArray.Length)
        {
            arraysEqual = false;

        }

        for (index = 0; index < userAnswers.Length; index++)
        {
            if (decompTimeArray[index] != userAnswers[index])
            {
                arraysEqual = false;
                wrong++;

            }
            else
            {
                arraysEqual = false;
                right++;

            }
            /*This part of the program will compare the arrays from 
             * methods 1,2 we use a for loop*/

        }

        if (arraysEqual)
        {
            Results Result = new Results();
            Result.correctAnswersLbl.Text = right.ToString("n");


        }
        else
        {
            Results Result = new Results();
            Result.incorrectAnswersLbl.Text = wrong.ToString("n");


        }
    }

    public void checkAnswersBtn_Click(object sender, EventArgs e)
    {

        Results Result = new Results();
        Result.userAnswer1Label.Text = newspaperLbl.Text;
        Result.userAnswer2Label.Text = aluminumCanLbl.Text;
        Result.userAnswer3Label.Text = glassBottleLbl.Text;
        Result.userAnswer4Label.Text = plasticbagLbl.Text;
        Result.userAnswer5Label.Text = cupLbl.Text;
        Result.correctAnswersLbl.Text = right.ToString("n");
        Result.incorrectAnswersLbl.Text = wrong.ToString("n");
        percentage = (wrong / 5) * 100;
        Result.percentageLbl.Text = percentage.ToString("p");
        this.Hide();
        Introduction Intro = new Introduction();
        Intro.Hide();
        Result.ShowDialog();






    }
}

}

如果错误是一个整数，您在这里进行整数除法：百分比=错误/5*100

例如，如果错的是4，你会得到4/5=0*100=0。因此，您将始终显示0

您需要将错误转换为双精度、十进制或浮点，或者将值5本身转换为更可取的值，因为您无法通过将其重写为5.0来获得“部分”答案

所以

---

将触发正确的除法类型；操作现在将计算为4/5.0=0.8*100=80

考虑调试代码。旁注：重复的数据总是令人痛苦的。您确实不需要错误地计算arraysEqual变量-在正常情况下，right+Error应该是数组的长度。。。

percentage = (int)((wrong / 5.0) * 100);
                            ^
                            |
      This will be a double-|
