Question

So, I’m having this array that adds elements one by one pressing a button, and it adds elements with this:
arreglo.Add(textBox1.Text.ToString());

I just want to limit the amount of elements it can add to the array, to 10. It can have up to ten elements, no more. How do i do that?

If it helps, these are parts of my code I think it can help:

ArrayList arreglo;
    public Form1()
    {
        InitializeComponent();
        arreglo = new ArrayList();
    }

and

        private void button5_Click(object sender, EventArgs e)
    {
        //Agregar
        arreglo.Add(textBox1.Text.ToString());
        /*if (arreglo.Count > 10)
        {
            listBox1.Items.Add("No more than ten elements");
        }*/
        this.textBox1.Clear();
        this.textBox1.Focus();
    }

And btw, i also need to do some calculations with that array, but i already have that covered.

You can simply solve this as:

private void button5_Click(object sender, EventArgs e)
    {
        //Agregar
        arreglo.Add(textBox1.Text.ToString());
        if (arreglo.Count > 10)
        {
            button5.Enabled = false;
        }
        this.textBox1.Clear();
        this.textBox1.Focus();
    }
