I have the following in a form:

public form1()
{
    InitializeComponent();
    this.FormClosing += new FormClosingEventHandler(this.confirmarFechamento_FormClosing);
}
private void confirmarFechamento_FormClosing(object sender, FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.UserClosing)
    {
        var result = MessageBox.Show(this, "Você tem certeza que deseja sair?", "Confirmação", MessageBoxButtons.YesNo);
        if (result != DialogResult.Yes)
        {
            e.Cancel = true;
        }
    }
}

How could I turn this into a class and just call it as a method? In case it would be class confirmarFechamento that has method confirmarFechamento , and in form1 would have the call of method confirmarFechamento .

Well you can create a class to handle all your Forms, so you would be more object-oriented, which would make your code reusable. So when you need a method that does some action for your Forms, be validate, close, cancel, save and etc ... Just reference it there and "abuse it", lol ... Hugs.

Just right click on your project, go to add and then click on class. I recommend that you name the class as a noun that represents it and for the method the action it does effectively. Your code would look like this +/-:

public form1()
{
    InitializeComponent();
    this.FormClosing += new FormClosingEventHandler(this.confirmarFechamento_FormClosing);
}


private void confirmarFechamento_FormClosing(object sender, FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.UserClosing)
    {
        if (! new Fechamento().ConfirmarFechamento())
            e.Cancel = true;
    }
}




public class Fechamento
{
    public bool ConfirmarFechamento()
    {
        var result = MessageBox.Show("Você tem certeza que deseja sair?", "Confirmação", MessageBoxButtons.YesNo);
        return result == DialogResult.Yes;
    }
}

But I do not think it would be very useful to create a class just for that.
