#178 – Throwing an Exception from a switch Statement

Instead of a break statement as a terminator of a case clause in a switch statement, you can also throw an exception.

            switch (surname)       // surname is a string
            {
                case "Aarhus":
                case "Enevoldsen":
                    Console.WriteLine("Norwegian");
                    break;
                case "Brosnan":
                case "McGill":
                    Console.WriteLine("Irish");
                    throw new ApplicationException("Software doesn't work for Irish people");
                default:
                    Console.WriteLine("UNKNOWN origin");
                    break;
            }
