Change properties of controls that were added at run time

Question

I have a form in which several buttons are added at runtime via the 'for' method

 public Form()
 {
 for (int i = 0 ... )
  Button b = new Button() 
  b.text =  (string) i ;
  etc..
  etc..
  }

. Now I want to change the text property of the buttons on a specific event. How can I do that? I tried a few things but no one worked. Because button variables are inside the method, they are not accessible from the outside.

thank

Variables are not important (although you can save them in one field List<T>if this makes the task easier). The usual way to do this is to browse through the collection Controls(recursively, if necessary).

foreach(Control control in someParent.Controls) {
    Button btn = control as Button;
    if(btn != null) {
        btn.Text = "hello world";
        // etc
    }
}

, ; , :

void DoSomething(Control parent) {
    foreach(Control control in parent.Controls) {
        Button btn = control as Button;
        if(btn != null) {
            btn.Text = "hello world";
            // etc
        }
        DoSometing(control); // recurse
    }
}
