Thread: Continue Yes Or No

I need to add a Continue yes or no command so that it returns the user to the menu if they type yes or says thanks and exits if you type no to this Code

Code:

Using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication9
{
    class Program
    {
        static ScreenHold()
        {
            Console.WriteLine("Press anykey to continue");
            Console.ReadKey();
        }

        static string Menu()
        {
            string choice = null;

            Console.WriteLine("\n1...Convert Miles to Kilometres\n");
            Console.WriteLine("\n2...Convert Kilometres to Miles\n");
            Console.WriteLine("\n3...Exit\n");

            ScreenHold();

            Console.WriteLine("\nEnter a choice(1,2 or 3)\n");
            choice = Console.ReadLine();

            return choice;
        }

        static double MilesToKilos(double M)
        {
            double Kilometres = M * 1.6093;
            return Kilometres;
        }

        static double KilosToMiles(double K)
        {
            double Miles = K * 0.62137;
            return Miles;
        }

        static void Main(string[] args)
        {
            string ch = null;

            do
            {
                //Clear the screen
                Console.Clear();
                //Display the menu, menu choice stored in ch
                ch = Menu();

                //Test the users choice
                switch (ch)
                {
                    case "1":
                        {
                            Console.WriteLine("\nInput  Miles to be converted\n");
                            double M = double.Parse(Console.ReadLine());

                            //Call the function MilesToKilos from main
                            double answer = MilesToKilos(M * 1.6093);
                            Console.WriteLine("Miles converted to Kilometres is: " + answer + '\n');

                            Console.WriteLine("\nPress any key to continue\n");
                            Console.ReadKey();
                            break;
                        }

                    case "2":
                        {
                            Console.WriteLine("\nInput kilometres to be converted \n");
                            double K = double.Parse(Console.ReadLine());

                            //Call the function KilosToMiles from main
                            double answer = KilosToMiles(K * 0.62137);
                            Console.WriteLine("Kilometres converted to Miles is: " + answer + '\n');

                            Console.WriteLine("\nPress any key to continue\n");
                            Console.ReadKey();
                            break;
                        }

                    case "3":
                        {
                            Console.WriteLine("\nProgram exiting...\n");
                            Console.WriteLine("\nPress any key to continue\n");
                            Console.ReadKey();

                            System.Environment.Exit(0);
                            break;
                        }

                }

            } while (ch != "3");

        }
    }
}

i didn't write most of that hence why i am asking

Code:

static void Main()
{
    Console.Clear();
    String ch = Menu();

    switch (ch)
    {
        case "1":
            Console.WriteLine("\nInput  Miles to be converted\n");
            double M = double.Parse(Console.ReadLine());

            //Call the function MilesToKilos from main
            double answer = MilesToKilos(M * 1.6093);
            Console.WriteLine("Miles converted to Kilometres is: " + answer + '\n');

            if (DoContinue)
                Main();
            else
                goto case "3";

            break;

        case "2":
            Console.WriteLine("\nInput kilometres to be converted \n");
            double K = double.Parse(Console.ReadLine());

            //Call the function KilosToMiles from main
            double answer = KilosToMiles(K * 0.62137);
            Console.WriteLine("Kilometres converted to Miles is: " + answer + '\n');

            if (DoContinue)
                Main();
            else
                goto case "3";

            break;

        case "3":
            Console.WriteLine("\nProgram exiting...\n");
            Console.WriteLine("\nPress any key to continue\n");
            Console.ReadKey();

            System.Environment.Exit(0);
            break;
    }
}

static bool DoContinue
{
    get
    {
        Console.WriteLine("\nContinue? (y/n)\n");
        char choice = 'y';

        while (true)
        {
            choice = Console.ReadKey().KeyChar;

            if (choice == 'y' || choice == 'n')
                break;
        }

        return choice == 'y';
    }
}

Code is self explanatory really. If you choose options 1 or 2, it will execute DoContinue which returns true if the user presses y to continue, false if the user presses n. I used goto because although a lot of programmers don't like to use it, I find it perfect for moving around inside a switch.

Thank you for your help theoobe
