I have on form 3 label. I want all these labels to put in an array so that later in the cycle you could do something like this:
(Windows Forms application)

for (int i = 0; i & lt; 3; i ++)
  labels [i] .text = "123";

list_labels.add (label1);
list_labels.add (label2);

{
  List_Labels [i] .text = "123";
}

label [] labels = new label [3];
for (int i = 0; i & lt; 3; i ++)

  this.controls.add (labels [i]);
}

And why do you need an array?

You can do the way as in this answer:

Create a method that will all pull.

Well, if you still need an array, you can almost also put them in the collection.
