vb.net storing "i" amount of textbox values in an array

My program has the ability to add textboxes during run time. The amount of textboxes on the form at run time is stored in the variable i. I need to create an array that stores all of the values from each of the textboxes in a place in the array up to the value of i. All of the textboxes have names that count upwards. Example:

And so on. In summary, is there any way I can store the values of i amount of textboxes, in an array? Any help will be appreciated, thanks.

You can use a dictionary to store the index of each text box and the associated text box value. Define the dictionary like this:

Dim dict As New Dictionary(Of String, String)

Populate it like this:

For index As Integer = 0 To 5
    dim txtBox = new TextBox
    txtBox.Name = index ' we'll make this index the name
    MyForm.Controls.Add(txtBox);
    dict.Add(index, txtBox )
Next

Then use it like this: (for example, when text changes and the text control is sender)

dim txtBox = (TextBox)sender;
dict(txtBox .Name) = txtBox .Text

Here are a couple of links for references to what I used above:

And take the code samples with a grain of salt. I'm not on a machine with an IDE.

When you create the textboxes at runtime, add the textbox into a list, similar to below:

    Dim textboxes As New List(Of TextBox)
    For I = 1 To 3
        Dim tb As New TextBox
        textboxes.Add(tb)
    Next

Then you can enumerate the list and process each textbox separately. Similar to below:

    For Each tb As TextBox In textboxes
        Dim value As String = tb.Text
    Next
