how to close a console application from inside loop with 2 switches

i'm creating a simple calculator and i've been trying to use switches to allow the user to select whether they want to add, subtract, multiply or divide their inputted values.

They can also type quit to exit the console. but after case quit: when i add a method of closing the console such as Environment.Exit(-1);

It throws up an error and using break; just brings me into my next switch (both of which are in the same while loop as the second one restarts the console).

Any ideas on what i can do?

            {

                case "add":

                    answer = (num1 + num2);

                    Console.WriteLine("your answer is {0:0.00}", answer);

                    break;

                case "subtract":

                    answer = (num1 - num2);

                    Console.WriteLine("your answer is {0:0.00}", answer);

                    break;

                case "multiply":

                    answer = (num1 * num2);

                    Console.WriteLine("your answer is {0:0.00}", answer);

                    break;

                case "divide":

                    answer = (num1 / num2);

                    Console.WriteLine("your answer is {0:0.00}", answer);

                    break;

                case "quit":



            }

What error do you get when you use "Environment.Exit(-1); "?

PaulF it tells me that control cannot fall out of switch from final case label (case "quit":)

case "quit":

    Environment.Exit(-1);

    break;
