How to convert foreach to react to the last element:

List myList = new List() {1, 2, 3, 4, 5};
Console.WriteLine("foreach version");
{
    foreach (var current in myList)
    {
        Console.WriteLine(current);
    }
}
Console.WriteLine("equivalent that reacts to last element");
{
    var enumerator = myList.GetEnumerator();
    if (enumerator.MoveNext() == true) // Corner case: empty list.
    {
        while (true)
        {
            int current = enumerator.Current;

            // Handle current element here.
            Console.WriteLine(current);

            bool ifLastElement = (enumerator.MoveNext() == false);
            if (ifLastElement)
            {
                // Cleanup after last element
                Console.WriteLine("[last element]");
                break;
            }
        }
    }
    enumerator.Dispose();
}
