Notwithstanding OriginalGriff's comments, the first thing you need to do is to create the array or List<T> that will contain the set.

Solution 1

Read my solution to the last time you posted this: How do I return textbox in loop from class using ASP.NET C#[^] - it hasn't changed in less than a day ...

Google Translate: "I don't know what I am doing, and I don't want to think about it."

Well ... that's a problem, because we can't give you code that will work.
You need to think about what you are trying to do, and work that out properly - then think about how to implement it. The code you show is useless for any practical purpose - and we can't change that without changing the "outside world" that calls it: which we have no access to or idea what it is trying to do either!

So stop throwing code together and hoping, and start thinking about your wider problem - it needs to be designed right or it's going to give you loads more problems in the future.

Solution 2

I will not share the exact code given you have been suggested how to move in detail earlier.
Though I will still nudge you with few more pointers (hopefully) on top of what Griff has already shared.

What/How array or list of textboxes would look like:

C#

//Array
TextBox[] myTextboxArray = new TextBox[2];
myTextboxArray[0] = TextBox1;
myTextboxArray[1] = TextBox2;

//List
List<TextBox> myTextboxList = new List<TextBox>();
myTextBoxList.Add(TextBox1);
myTextBoxList.Add(TextBox2);
mytextBoxList.Add(TextBox3);

Couple of learning articles:
Arrays - C# Programming Guide | Microsoft Docs[^]
Create controls dynamically and retrieve values from it in ASP.Net using C# and VB.Net[^]

Learn and try again. This is for your benefit as these come under basics.

i figured it out myself
thing that i learned was that if you want to return multiple values from function using loop then you will have to create an Array function instead of creating normal function.

C#

public TextBox[] txtbox(int count)
        {
                                    TextBox[] txtbox;
            txtbox = new TextBox[count];
            int i = 0;
            while(i<txtbox.Length)
                        {
                TextBox t = new TextBox();
                txtbox[i] = t;
                txtbox[i].Text= "inserted textbox array"+i.ToString();
                mypanel.Controls.Add(txtbox[i]);
                i++;
            }
            return txtbox;
        }
