Casino en c# (Orientado a objetos)

primero necesitaremos los siguientes elementos

 

codigo del programa

public partial class casino : Form

    {

        int c = 0, n1 =0,n2=0,n3=0,n4=0;

        Random objeto = new Random();

        public casino()

        {

            InitializeComponent();

        }

        private void be_Click(object sender, EventArgs e)

        {

            timer1.Enabled = true;

            timer2.Enabled = true;

            timer3.Enabled = true;

            timer4.Enabled = true;

            be.Enabled = false;

            button2.Enabled = true;

            c = 0;

        }

        private void timer1_Tick(object sender, EventArgs e)

        {

            n1 = objeto.Next(0, 10);// n1=9

            t1.Text = Convert.ToString(n1);//n1 = "9"

        }

        private void timer2_Tick(object sender, EventArgs e)

        {

            n2 = objeto.Next(0, 10);// n2=9

            t2.Text = Convert.ToString(n2);//n2 = "9"

        }

        private void timer3_Tick(object sender, EventArgs e)

        {

            n3 = objeto.Next(0, 10);// n3=9

            t3.Text = Convert.ToString(n3);//n3 = "9"

        }

        private void timer4_Tick(object sender, EventArgs e)

        {

            n4 = objeto.Next(0, 10);// n4=9

            t4.Text = Convert.ToString(n4);//n4 = "9"

        }

        private void button2_Click(object sender, EventArgs e)

        {

            c++;

            if (c == 1) timer1.Enabled = false;

            if (c == 2) timer2.Enabled = false;

            if (c == 3) timer3.Enabled = false;

            if (c == 4)

            {

                timer4.Enabled = false;

                be.Enabled = true;

                button2.Enabled = false;

                if ((n1 == n2) && (n2 == n3) && (n3 == n4))

                {

                    MessageBox.Show("Ganaste", "felicidades", MessageBoxButtons.OK);

                }

                else

                {

                    MessageBox.Show("Perdiste", "Sigue participando", MessageBoxButtons.OK, MessageBoxIcon.Error);

                }

            }

        }

        private void button1_Click(object sender, EventArgs e)

        {

            if (MessageBox.Show(" Deseas salir ", "Salir", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)

            {

                MessageBox.Show("Ud decidio salir", "adios", MessageBoxButtons.OK, MessageBoxIcon.Warning);

                this.Close();

            }

            else

            {

                MessageBox.Show("Ud decidio no salir", "...");

            }

        }

        private void casino_Load(object sender, EventArgs e)

        {

        }

    }

el resultado será el siguiente
