How to create a counter that counts unrighteous inputs

Question

  static void MainWindow()
    {
        
        Console.Clear();
        Console.WriteLine("Menu");
        Console.WriteLine("");
        Console.WriteLine("1. Information");
        Console.WriteLine("2. Contact");
        Console.WriteLine("3. Extra");
        Console.WriteLine("q. Exit");
        string myOptions;
        myOptions = Console.ReadLine();

        switch (myOptions)
        {
            case "1":
                Information();
                break;
            case "2":
                Contact();
                break;
            case "3":
                Extra();
                break;
            case "q":
                Exit();
                break;

            default:
                Console.Clear();
                Console.WriteLine("Input is wrong");
                Console.ReadKey();
                MainWindow();
                break;
                


        }

        Console.ReadLine();
    }

I make a console menu and I need a counter that will count wrong entries. if it hits 5 times, the user is thrown back to the main menu.

I was trying to do this with while statement but it didnt work for me.
