Change multiple images in list with one button

Question

New to programming. I'm working on a Windows Form Application for the Petals Around the Rose game for school, and although our instructor has shown us how to change individual pictureboxes upon clicking then, I want to make a button that can change all of them at once/'reroll' the dice.

Some code:

    private void frmDisplay_Load(object sender, EventArgs e)
    {
        // Create list object to hold dice images
        diceArray = new List<MyPictureBox>();

        for (int i = 0; i < 5; i++)
        {
            MyPictureBox picBox = new MyPictureBox(i + 1);
            picBox.Image = RandomDice.GetRandomDice();
            picBox.Click += new System.EventHandler(pictureBox_Click);
            this.Controls.Add(picBox);
            this.Controls.Add(picBox.TheLabel);
        }           
    }

The above code creates 5 pictureboxes when the form loads, and pulls from my RandomDice class, here:

class RandomDice
{
    private static Random randomGen = new Random();
    private static Image[] imgList = new Image[6];

    public static Image GetRandomDice()
    {
        int i = 0;
        ResourceSet rsrcSet = Properties.Resources.ResourceManager.GetResourceSet(CultureInfo.CurrentCulture, true, true);
        foreach (DictionaryEntry entry in rsrcSet)
        {
            imgList[i] = (Image) entry.Value;
            i++;
        }
        i = randomGen.Next(0, imgList.Length);
        return imgList[i];
    }
}

I have an event set up for a button click, but I'm not sure how to make it so the button changes all my dice images at once.

Any advice?

Thank you!

You have to iterate through the array. And then change the image inside your for loop.

    /// <summary>Update the image list with random dice images.</summary>
    public static void UpdateDices()
    {
        // Iterate through the image array.
        for (var i = 0; i < imgList.Length; i++)
        {
            // Update the dice image.
            imgList[i] = GetRandomDice();
        }
    }
