Cycling through multiple strings c#

I have 10 strings, all named q1,q2,q3, etc.

My question is, on button click, how do I make them cycle and display within a button?

Current code: 

private void nButton_Click(object sender, EventArgs e)
    {
        for (int g = 0; g <= 10; g++)
        {
            rBox.Text = q(g);
        }
    }

Clearly q(g) does not cycle appropriately, so I have come to you, Oracles of code, how would I accomplish this?

** Alternatively, if I wanted to remove the for loop, and instead would just want to increment g by one every time until 10, I assume the structure would resemble something like the following: 

private void nButton_Click(object sender, EventArgs e)
    {
        g++
            rBox.Text = q(g);       
    }

However the question persists, how would I cycle through these strings?

EDIT: I've discovered these neat things called Lists, so I simply created a new list with

        List<string> questionNumber = new List<string>();

Then add the string

questionNumber.Add(q1);

As lastly display it through the text box with simple incrementation

private void nButton_Click(object sender, EventArgs e)
    {
        g++;

            rBox.Text = questionNumber[g];

    }

The easiest way would be putting them into an array and iterate over the array whenever you wanna operate on your strings.For example:

var values = new [] { q1, q2, q3, ... };

for (int g = 0; g < 10; g++)
{
   rBox.Text += values[g];
}

If your intention was to display one string at a time, on each click you can do so by creating a counter variable outside of the click event and increment it per click and just fecth the string at that index:

int index = 0;
private void nButton_Click(object sender, EventArgs e)
{
    if(index != values.Length) 
    {
       rBox.Text = values[index];
       index++;
    }    
}

You need to declare values a field or property of your class, and initialize it with your strings.In fact you can completely remove the variables and just use an array or list to store your values.
