This is my code setup

        private void button1_Click(object sender, EventArgs e)
        {
            // Create a new ArrayList
            ArrayList numbers = new ArrayList();
            // Add some numbers to the list
            numbers.Add(7);
            numbers.Add(21);
            // Get the numbers out of the list
            // Notice a cast is required because
            // ArrayList only contain objects (untyped)
            // This also performs an unboxing operation
            int numA = (int)numbers[0];
            int numB = (int)numbers[1];
        }

Thats my control memory list, but i don't know how to go back and forth with it

What are you trying to do with the ArrayList? You'd also be better off using the List<>, as you won't have to cast.

Well I have a colour green on backgound at the start, and I want it to remember that coz when i press the button the colour wiull change to blue, and i want to be able to go back and forth through that memory list

If you are working with an array of items and you know their type, then I would recommend wither using an array (for example, int[] - but you will need to know the size of it) or implement a list (List<int>) of integers.

If you choose to work with arrays, you will work with the standard assignment/reading procedure. For example:

myArray[9] = 0;

int readValue = myArray[9];

With a List<int> you will do it this way:

List<int> listOfInt = new List<int>();
listOfInt.Add(1);

int readValue = listOfInt[0];

I'll use int<> it makes more scene, but it don't show how you can use them

[Adkins]

I am completely not understanding the question. If you wanna switch back and forth between them, why not just use a simple if statement.

if (numA)
{
    numB
}
else
{
    numA
}
