How do I get the property values of dynamically loaded Web control?

web| dynamic I have a page that dynamically loads two controls, TxtQuestion1 and TxtQuestion2,
Of these, 1, 2 are determined by the values in an array: The loading method is as follows:
for (int i=0;i<=arrlang.getupperbound (0); i++)
{
TextBox myTextBox1 = new TextBox ();
Mytextbox1.id = "Txtquestion" + arrlang[i]. ToString ();
PLACEHOLDER1.CONTROLS.ADD (MyTextBox1);
}

Now I'm going to get what the user has entered in these two dynamically loaded text boxes, and they need to be implemented using arrays as well. How to do it?
I think I need to use something like eval (), but I don't know the exact method.

Answer:
((TextBox) Faqplaceholder.findcontrol ("txtquestion" + arrlang[i]. ToString ())). Text;
