How to make a window close on button click?

Question

WPF

Writing:

private void Exit_Click(object sender, RoutedEventArgs e)
        { 
            this.Close(); // ошибка
        }

Error: 'Menu' does not contain a 'Close' definition, and no accessible extension method 'Close' could be found that accepts the type 'Menu' as its first argument (possibly missing a using directive or an assembly reference).

Answer 1

App.Current.MainWindow.Close();
PS Or Application instead of App, depending on your name
