I wish this helpful for you It sounds like you've already solved it. Make UniqueValue be a member of the form class. Put it in the public section of the class declaration, for example.
code :
type
  TForm24 = class(TForm)
  public
    UniqueValue: array of string;
  end;

How to generate dynamic multi-dimensional list or array and insert data accordingly based on a dynamic SQL Server table

will help you I've solved this statically with Tuple, but not dynamically. I think I should re-fresh my tuple list periodically. But at least, it works now!
Any suggestions are welcome! !

Is there a List<T> like dynamic array that allows access to the internal array data in .NET?

it should still fix some issue
Is there another data structure in .NET that allows this, or do I have to implement my own dynamic array?

Hope this helps Use join() function on your array and pass - as parameter. It concatenates all items with passed parameter and returns you a string.
As an example you can see
code :
var img_arr = [1,2,3,4,5,6,7,8,9];
var arr = img_arr.join('-');

console.log(arr);

it should still fix some issue If you're looking to 'store' the form-data (records) you need a persistent storage mechanism (file/database). However, you can work on your data in a session, see the records that are 'submitted' during a session, stored in a session variable (array).
code :
<?php
session_start();
$arr = []; //initialize empty array
$name2 = $family2 = $email2 = $age2 = "";
?>

<!doctype html>
<html>
<body>
<form name="myform" id="cls-frm" action="" method="post">
    <div>
        <label for="name">Enter your first name: </label>
        <input type="text" name="name" required>
    </div>
    <div>
        <label for="name">Enter your family name: </label>
        <input type="text" name="family" required>
    </div>
    <div>
        <label for="name">Enter your email: </label>
        <input type="email" name="email" required>
    </div>
    <div>
        <label for="name">Enter your age: </label>
        <input type="text" name="age" required>
    </div>
    <div>
        <input type="submit" name="submit" value="submit">
    </div>
</form>


<form name="myform2" id="cls-frm2" action="" method="post">
    <div>
        <label for="name">clear all my records currently in session array</label>
        <input type="submit" name="clear" value="clear data">
    </div>
</form>

<?php
/* clear the data in session array */
if (isset($_POST['clear'])) {
    $_SESSION = [];
}

if (isset($_POST['submit'])) {
    $name2 = $_POST["name"];
    $family2 = $_POST["family"];
    $email2 = $_POST["email"];
    $age2 = $_POST["age"];

    $arr = ["$name2", "$family2", "$email2", "$age2"];
    $_SESSION['arr2demin'][] = $arr; // create a new sub-array for each set of data

    echo "<h1>my current session records:</h1> <br>";
    echo '<pre>';
    print_r($_SESSION['arr2demin']);
    echo '</pre>';
    echo 'NOTE: if you want to store your session data persistently, you need to save session records to file/database...';
}
// database / file storage code here...
?>
</body>
