Adding text between listboxes items

[Haddad]

I'm using vb.net form.

I have 8 listboxes (listbox1 , listbox2,listbox3..) each one contains many items and another empty listbox (listbox10). I'm trying to add first listboxes items into the listbox10

ex: listbox1 first items is "A" , listbox2 first items is "B" , listbox3 first items is "C"...etc . Now listbox10 first item must be "Abc...";

The problem is i want to add text ( string or number) between each listbox

ex: listbox1 first items is "A" , listbox2 first items is "B" , listbox3 first items is "C"...etc . Now I want listbox10 first item to be "The letters A is before B and now C"

The main idea is to combine all listboxes items and adding text between them to create a meaningful sentence

here is my code

Dim controls = New List(Of ListBox)() From _
{ListBox1, ListBox2, ListBox3, ListBox4, ListBox5, ListBox6, ListBox7, ListBox8}
Dim minCount = Controls.Min(Function(x) x.Items.Count)
For x = 1 To minCount - 1
ListBox10.Items.Add(String.Join(" ", controls.Select
(Function(lb) lb.Items(x).ToString)))
Next

End Sub

This question really has nothing at all to do with ListBoxes. It boils down to the fact that you have a number of Strings and you want to build another String from them and some literal text. That is an example of how you identify what the actual problem is and not make it harder to solve by including irrelevant factors. It's for that sort of thing that the String.Format method exists. As a simple example:

Dim text = String.Format("The name is {0}.  {1} {0}.",
                         familyNameTextBox.Text,
                         givenNameTextBox.Text)

If the user were to type "James" into the given name field and "Bond" into the family name field then `text` would contain "The name is Bond. James Bond.". As you can see, it's simple to insert whatever values you want into literal text wherever you want.
