Why can’t I display Messageboxbuttons if it’s not a string?

Question

'Cause I’m having trouble showing off MessageBoxButtons if it is not a string?

static void Main()
{
    string texto = "Minha primeira MessageBox";
    MessageBoxButtons botao = MessageBoxButtons.OKCancel;
    DialogResult result;
    result = MessageBox.Show(texto, botao);
    if(result == DialogResult.OK)
    {
        MessageBox.Show("Isso ai");
    }
}

Answer 1

Because this syntax does not exist. There is only one method that accepts MessageBoxButtons if there are 2 parameters string before (the second is caption):

result = MessageBox.Show(texto, "Proceder", botao);

I put in the Github for future reference.
