Use the Substring overload which accepts starting index and amount of characters to cut:

lbl_diasemana.Text = diasemana.Substring(0, 3);

You could use the DateTime.Today.ToString(...) method with the appropriate format string and culture like this:

System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("pt-BR");
lbl_diasemana.Text = DateTime.Today.ToString("ddd", culture);

You could probably do it one line if you want: lbl_diasemana.Text = new System.Globalization.CultureInfo("pt-BR").DateTimeFormat.GetDayName(DateTime.Today.DayOfWeek).Substring(0, 3); – David P Jun 20 '17 at 20:53
