关于GUI的更多问题

我正在做学校的作业，我有点迷路了。GUI应该有一个文本输入框，您可以在其中输入SAT分数，然后它将该分数转换为ACT分数，并将ACT分数显示到一个文本框中，然后在另一个文本框中显示该分数是否足够高。

根据SAT是否符合这些数字，将SAT分数转换为ACT分数。我不知道该怎么写才能知道SAT的输入分数在ACT中的位置，并将其显示在那个文本框中。

    SAT score > 1600    = ACT score 37 (high enough)
    SAT score from 1560-1590    = ACT score 36 (high enough)
    SAT score from 1510-1550    = ACT score 35 (high enough)
    SAT score from 1460-1500    = ACT score 34 (high enough)
    SAT score from 1410-1450    = ACT score 33 (too low)
    SAT score from 1360-1400    = ACT score 32 (too low)
    SAT score < 1350    = ACT score 31 (too low)

还必须编写一个try/catch来确保输入的是整数，而不是其他任何东西。这一点我理解。

这是我的代码到目前为止没有任何错误。

    private void convertButton_Click(object sender, EventArgs e)
    {

        try
        {
            double satscore;
            satscore = Convert.ToDouble(satScoreTextBox.Text);
        }
        catch
        {
            MessageBox.Show("Invalid input, value must be numeric");
            satScoreTextBox.Focus();
            satScoreTextBox.SelectAll();
        }

    }
    private void exitButton_Click(object sender, EventArgs e)
    {
        this.Close();
    }

}

}

谢谢你，任何帮助都是感激的!

为什么不使用几个if语句呢?(还有，我以为你说的是整数?你为什么要用替身?)我认为你下次问这样的问题之前应该多做一些调查。

 private void convertButton(object sender, EventArgs e)
 {
     try
        {
            int satScore;
            satScore = Int32.Parse(satScoreTextBox.Text);
            checkSatScore(satScore);
        }
        catch
        {
            MessageBox.Show("Invalid input, value must be numeric");
            satScoreTextBox.Focus();
            satScoreTextBox.SelectAll();
        }
 }
 private void checkSatScore(int satScore)
 {
     int actScore;
     if(satScore > 1600)
         actScore = 37;
     else if (satScore > 1560)
         actScore = 36;
     else if (satScore > 1510)
         actScore = 35;
     else if (satScore > 1460)
         actScore = 34;
     else if (satScore > 1410)
         actScore = 33;
     else if (satScore > 1360)
         actScore = 32;
     else
         actScore = 31
     if(actScore > 33)
         satScoreTextBox.Text = "ACT Score " + actScore + "(high enough)";
     else
         satScoreTextBox.Text = "ACT Score " + actScore + "(too low)";
 }

private void convertButton_Click(object sender, EventArgs e)
{
    try
    {
        String message="";
        double satscore;
        int actscore=0;
        satscore =Double.Parse(satScoreTextBox.Text);
        if(satscore>1600)
        {
            actscore=37;
            message="ACT score "+actscore+" (high enough)";
        }
        else if(satscore>=1560&&satscore<=1590)
        {
            actscore=36;
            message="ACT score "+actscore+" (high enough)";
        }
        else if(satscore>=1510&&satscore<=1550)
        {
            actscore=35;
            message="ACT score "+actscore+" (high enough)";
        }
        else if(satscore>=1460&&satscore<=1500)
        {
            actscore=34;

        }
        else if(satscore>=1410&&satscore<=1450)
        {

        else
        {
            actscore=31;
            message="ACT score "+actscore+" (too low)";
        }
    }
    catch
    {
        MessageBox.Show("Invalid input, value must be numeric");
        satScoreTextBox.Focus();
        satScoreTextBox.SelectAll();
    }
}
