如何使用for循环将选定单选按钮的结果显示到一个文本框中？

Question

I am making a html form and when the user submits the form an aspx page will load to display the results of the form. I have 20 questions total with 5 radio buttons each. For some reason when I try to retrieve the selected radio buttons thru a for loop, it only displays one answer. What am I doing wrong?

I have tried changing the values in the for loop but it just seems to not be displaying correctly.

Here's the code for the aspx.cs

public void DisplayResults(double[] results)
    {
        try
        {  
            int q = 1;
            for (int i = 0; i <= 19; i++)
            {
                if (i == 0)
                {
                    txtResults.Text = "Course Results";
                    if (results[i] == 1)
                    {
                        txtResults.Text += "Q" + q + ": Strongly Disagree";
                    }
                    else if (results[i] == 2)
                    {
                        txtResults.Text += "Q" + q + ": Disagree";
                    }
                    else if (results[i] == 3)
                    {
                        txtResults.Text += "Q" + q + ": Neutral";
                    }
                    else if (results[i] == 4)
                    {
                        txtResults.Text += "Q" + q + ": Agree";
                    }
                    else if (results[i] == 5)
                    {
                        txtResults.Text += "Q" + q + ": Strongly Agree ZERO";
                    }
                }

I want to be able to display each result for each question in the same multi-line textbox like so but it be split between courses and professor questions:

COURSES

Q1: Disagree

Q2: Neutral

Q3: Neutral

etc...

PROFESSOR

Q1: Disagree

Q2: Neutral

Q3: Neutral

etc...

Answer 1

First: It's because you've not incremented the q value,

Incorrect because q is always 1:

txtResults.Text = "Course Results";
if (results[i] == 1)
{
    txtResults.Text += "Q" + q + ": Strongly Disagree";
}

Second, you've allowed the program to write for cases where i=0 and i=11

Full answer:

public void DisplayResults(double[] results)
{
    try
    {  
        for (int i = 0, q = 1; i <= 19; i++, q++)
        {
            if (i == 0)
            {
                txtResults.Text += "Course Results";
            }
            if (i == 11)
            {
                txtResults.Text += "Professor Results";
            }
            txtResults.Text += "Q" + q ": ";
            if (results[i] == 1)
            {
                txtResults.Text +="Strongly Disagree";
            }
            else if (results[i] == 2)
            {
                txtResults.Text +="Disagree";
            }
            else if (results[i] == 3)
            {
                txtResults.Text +=": Neutral";
            }
            else if (results[i] == 4)
            {
                txtResults.Text +="Agree";
            }
            else if (results[i] == 5)
            {
                if(i == 0 )
                txtResults.Text +="Strongly Agree ZERO";
                else if(i == 11 )
