help pls...i don't know how to do this:
Q1? After the Roll button is pressed, a timer will be enabled to generate random die rolls every 1/10 of a second...
Q2?, how can make dice#1 an integer or count as 1. because after the roll stop, need to add them all and display score.
i am using 5 picturebox, the imagelist has 6 picture(dice 1 to 6), 2 buttons(roll and play again).
Thank you...

C#

private Random m_rnd = new Random();
        private int[] i_Array = new int[5] { 0, 1, 2, 3, 4 };
        public Form1()
        {
            InitializeComponent();
            
            pictureBox1.Image = imageList1.Images[i_Array[0]];
            pictureBox2.Image = imageList1.Images[i_Array[1]];
            pictureBox3.Image = imageList1.Images[i_Array[2]];
            pictureBox4.Image = imageList1.Images[i_Array[3]];
            pictureBox5.Image = imageList1.Images[i_Array[4]];
        }

        private void btn_roll_Click(object sender, EventArgs e)
        {
            pictureBox1.Image = imageList1.Images[m_rnd.Next(0, 6)];
            pictureBox2.Image = imageList1.Images[m_rnd.Next(0, 6)];
            pictureBox3.Image = imageList1.Images[m_rnd.Next(0, 6)];
            pictureBox4.Image = imageList1.Images[m_rnd.Next(0, 6)];
            pictureBox5.Image = imageList1.Images[m_rnd.Next(0, 6)];

        }

I think you are going about this the wrong way. This is how I would do it. I am assuming you are trying to get random results from 5 dice, and setting the image for 5 pb's to correspond to each number rolled. I aslo assume your imageList contains six images which correspond to the six sides of a dice. First off I would store my PictureBoxes in a List<PictureBox> . That way I could access them from a loop. I would also have a List<int> to store my dice results, so i would declare them as form level variables, along with an int to store the total rolled and an instance of the Random class to generate random results :-

C#

Random r = new Random();
        List<int> diceResults = new List<int>();
        List<PictureBox> dice = new List<PictureBox>();
        int diceTotal;

Then I would add my PictureBoxes to my dice list in the form constructor(could also be done in FormLoad event) like this;

C#

public Form1()
        {
            InitializeComponent();
            dice.Add(pictureBox1);
            dice.Add(pictureBox2);
            dice.Add(pictureBox3);
            dice.Add(pictureBox4);
            dice.Add(pictureBox5);
        }

then in the click event of the roll button, you just construct a loop to generate random numbers and add as you go like this:-

C#

private void button1_Click(object sender, EventArgs e)
        {
            diceTotal = 0;
            diceResults.Clear();
            for (int i = 0; i <= 4; i++)
            {
                diceResults.Add(r.Next(1,6));
                int imageNumber = diceResults[i] - 1;
                dice[i].Image = this.imageList1.Images[imageNumber];
                diceTotal += diceResults[i];
            }
            lblDiceTotal.Text = diceTotal.ToString();
        }

notice i used 1 as the minimum for my random generator so I don't get 0 as a result, this means I must subtract 1 when want to generate the image index.

Hope this helps

i solved the first question, now I'm having a hard time doing this:
When a label is clicked, the background color will be changed to red, indicating that that particular die will not be rolled. If the user clicks on a red die again, the color will return to green, indicating that that die will be rolled.

C#

        Random m_rnd = new Random();
        List<int> diceResults = new List<int>();
        List<picturebox> die = new List<picturebox>();
        PictureBox[] dice = null;
        int i_diceTotal = 0;
        //int totalScore = 0;
        int[] i_Array = new int[5];
        int rolls = 0;
        int i_rolling = 0;
        public Form1()
        {
            InitializeComponent();
            die.Add(pictureBox1);
            die.Add(pictureBox2);
            die.Add(pictureBox3);
            die.Add(pictureBox4);
            die.Add(pictureBox5);
            dice = new PictureBox[5]
            {
                pictureBox1,
                pictureBox2,
                pictureBox3,
                pictureBox4,
                pictureBox5
            };
            for (int i = 0; i < 5; i++)
            {
                dice[i].Image = imageList1.Images[i];
                i_Array[i] = i;
            }

            lbl_totalscore.Text = "0";
            lbl_rollscore.Text = "0";
            timer1.Interval = 10;

        }

        private void Form1_Load(object sender, EventArgs e)
        {
            
        }

        private void btn_Roll_Click(object sender, EventArgs e)
        {
            
            rolls++;
            lbl_rollscore.Text = rolls.ToString();
            if (rolls == 3)
            {
                btn_Roll.Enabled = false;
            }
            timer1.Start();
            
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            for (int i = 0; i < 5; i++)
            {
                i_Array[i] = m_rnd.Next(0, 6);
                dice[i].Image = imageList1.Images[i_Array[i]];
            }

            i_rolling++;
            if (i_rolling < 10) return;
            timer1.Stop();
            //int rollScore = 0;
            i_diceTotal = 0;
            diceResults.Clear();
            for (int i = 0; i <= 4; i++)
            {
                diceResults.Add(m_rnd.Next(1, 6));
                int imageNumber = diceResults[i] - 1;
                die[i].Image = this.imageList1.Images[imageNumber];
                i_diceTotal += diceResults[i];
            }
            lbl_totalscore.Text = i_diceTotal.ToString();
            
        }

        private void btn_playagain_Click(object sender, EventArgs e)
        {
            rolls = -1;
            dice = new PictureBox[5]
