比较两个数组，同时计算正确答案和错误答案的数量

我写了一个程序，用户在其中玩游戏并猜测答案。除了我的数组之外，一切都很好，程序有两个数组，第一个是usersAnswers，它包含用户的选择，第二个是decodeTimeArray，它包含正确的答案。我写了一个方法，程序将比较两个数组，计算用户得到的正确和错误答案的数量，并将其值放在两个单独的标签中。该程序运行良好，但正确和不正确的标签总是给我0，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。这是我的代码：

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();



    }
}
