Good I'm doing in window form a mini system that when there are 2 buttons

1: first button called a raffle is to appear at a certain time and my 8 numbers appear label 2: regenerate button is only bleach is to say that they are visible again

but my problem is that when I first put the draw button shows correctly a certain time,

Now when he finishes and I put the second button and then I press the first button, he shows me suddenly.

This is the part of the window form view

this is my code for the first button:

 private void button3_Click(object sender, EventArgs e)
        {
 SetInterval(1000, (obj, ev) =>
            {
                if (!lbln1.Visible)
                {
                    lbln1.Show();
                }
                else if (!lbln2.Visible)
                {
                    lbln2.Show();
                }
                else if (!lbln3.Visible)
                {
                    lbln3.Show();
                }
                else if (!lbln4.Visible)
                {
                    lbln4.Show();
                }
                else if (!lbln5.Visible)
                {
                    lbln5.Show();
                }

                else if (!lbln6.Visible)
                {
                    lbln6.Show();
                }
                else if (!lbln7.Visible)
                {
                    lbln7.Show();
                }
                else if (!lbln8.Visible)
                {
                    lbln8.Show();
                }
                else if (!label1.Visible)
                {
                    label1.Show();
                }

                else if (!lblcliente.Visible)
                {
                    lblcliente.Show();
                }
                else if (!lbloficina.Visible)
                {
                    lbloficina.Show();
                }
                else if (!lblfelicitaciones.Visible)
                {
                    lblfelicitaciones.Show();
                }
                else if (!lbldireccion.Visible)
                {
                    lbldireccion.Show();
                }

            });
}

Second Button:

private void button1_Click(object sender, EventArgs e)
        {

             DialogResult res = MessageBox.Show("Desea Sortear Nuevamente?", "Aviso del sistema",
                            MessageBoxButtons.YesNo,
                            MessageBoxIcon.Question);
             if (res == DialogResult.Yes)
             {lbln1.Text = "";
                 lbln2.Text = "";
                 lbln3.Text = "";
                 lbln4.Text = "";
                 lbln5.Text = "";
                 lbln6.Text = "";
                 lbln7.Text = "";
                 lbln8.Text = "";
                 lblcliente.Text = "";
                 lblfelicitaciones.Text = "";
                 lblnoesganador.Text = "";
                 lbloficina.Text = "";
                 lbldireccion.Text = "";
                 label1.Text = "";

                 MessageBox.Show("Se regenero el sorteo correctamente", "Aviso del Sistema");
                 button2.Enabled = false;

             }
        }

this is my void SetInterval

private void SetInterval(int interval, EventHandler callback)
        {
            //Creo el temporizador

            Timer timer = new Timer();


            //Le establezco el intervalo en el que va a repetir la operación
            //timer.Interval = interval;

            timer.Interval = interval;

            //Asigno que se ejecutara al llegar el tiempo estimado
            timer.Tick += (obj, ev) =>
            {
                //En este caso ejecuto el callback que paso como parametro
                callback(obj, ev);

            };
            //Inicializo el temporizador
            timer.Start();

        }

Is it possible to deactivate the gps to reduce the battery consumption in an app? What is the difference between selecting by ID or ClassName?

You are complicating something, that in winforms is done with the controls of the form itself.

Add in the form 6 labels, 2 buttons and a TIMER control.

Leave the default names, except for the timer , change it to tmrMostrar and put the property interval in 1000.

You will have to connect the events that I describe below to your controls. There is an event for the first button, another for the second and a tick event for the timer.

The simplified code with explanations in the comments is:

//Lista de los labels a ir mostrando
private List<Label> labels = new List<Label>();
//Siguiente label a mostrar
private int LabelAMostrar = 1;
//El valor del ultimo label, o la cantidad
private int MaximoLabel = 6;

public Form1()
{
    InitializeComponent();
    //Armo un array de controles, se puede recorrer el form, pero asi es mas rapido
    labels.Add(label1);
    labels.Add(label2);
    labels.Add(label3);
    labels.Add(label4);
    labels.Add(label5);
    labels.Add(label6);
    cambiarEstadoLabels(false);
}

private void button1_Click(object sender, EventArgs e)
{
    //Empezar el timer
    tmrMostrar.Start();
    //apagar el boton
    button1.Visible = false;
}

private void cambiarEstadoLabels(bool estado)
{
    foreach (Label l in labels)
    {
        l.Visible = estado;
    }
}

private void tmrMostrar_Tick(object sender, EventArgs e)
{
    //Esto se podria hacer mucho mejor con linq
    foreach (Label l in labels)
    {
        if (l.Name == $"label{LabelAMostrar}")
        {
            l.Visible = true;
            LabelAMostrar += 1;
            if (LabelAMostrar > MaximoLabel)
            {
                //apago el timer
                tmrMostrar.Stop();
                //Muestro el boton de reseteo
                button2.Visible = true;
            }
            //si llegue aca, es que ya encontre el label a mostrar
            return;
        }
    }
}

private void button2_Click(object sender, EventArgs e)
{
    cambiarEstadoLabels(false);
    button2.Visible = false;
    button1.Visible = true;
    LabelAMostrar = 1;
}

This code will show a label per second, until the last one.
