Question

I am trying to assign button controls text dynamically by using a loop like the following:

int ButtonNumber = 1;

while (ButtonNumber < 10)
{
    //WHAT TO DO HERE!?
    ButtonNumber++;
}

I wanna avoid the following:

button1.Text = "";
button2.Text = "";
button3.Text = "";
button4.Text = "";
button5.Text = "";
button6.Text = "";
button7.Text = "";
button8.Text = "";
button9.Text = "";

Answer 1

Ideally, don’t have button1, button2 etc as variables in the first place. Have a collection (e.g. a List<Button>):

private List<Button> buttons = new List<Button>();

(EDIT: You’d need to populate this somewhere, of course…)

then to update the text later:

for (int i = 0; i < buttons.Count; i++)
{
    buttons[i].Text = "I'm button " + i;
}

This doesn’t play terribly nicely with the designer, unfortunately.

You can fetch a control by ID, but personally I try not to do that. If you really want to:

for (int i = 1; i <= 10; i++)
{
    Control control = Controls["button" + i];
    control.Text = "I'm button " + i;
}
