Foreach Random Number Always Returning 0

I'm trying to make a simple lottery generator, my random number always returns 0 in all txt boxes. I'd like to put the random number from my array into each text box, This is there code:

    public partial class Form1 : Form
{
    private int[] randomArray = new int[6];

    int Min = 1;
    int Max = 60;

    Random rand = new Random();

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void genBtn_Click(object sender, EventArgs e)
    {


        foreach (int value in randomArray)
        {
            rand.Next(Min, Max);
        }


        boxNum1.Text = randomArray[0].ToString();
        boxNum2.Text = randomArray[1].ToString();
        boxNum3.Text = randomArray[2].ToString();
        boxNum4.Text = randomArray[3].ToString();
        boxNum5.Text = randomArray[4].ToString();
        boxNum6.Text = randomArray[5].ToString();
    }
}
