using System.Linq;

using System.Text;

namespace OperationConsole

{

    class Program

    {

        static void Main(string[] args)

        {

            int Number1, Number2;

            char option;

            int Result;

            Console.WriteLine("Enter the First Number:"); 

            Number1 = Convert.ToInt32(Console.ReadLine()); 

 

            Console.WriteLine("Enter the Second Number:"); 

            Number2 = Convert.ToInt32(Console.ReadLine()); 

 

            Console.WriteLine("Main Menu"); 

            Console.WriteLine("1. Addition"); 

            Console.WriteLine("2. Subtraction"); 

            Console.WriteLine("3. Multiplication"); 

            Console.WriteLine("4. Division"); 

 

            Console.WriteLine("Enter the Operation Number To Perform Operation"); 

            option = Convert.ToChar(Console.ReadLine()); 

 

            switch (option) 

            { 

                case '1': 

                    Result = Number1 + Number2; 

                    Console.WriteLine("Addition is:{0}", Result); 

                    break; 

                case '2': 

                    Result = Number1 - Number2; 

                    Console.WriteLine("Subtraction is:{0}", Result); 

                    break; 

                case '3': 

                    Result = Number1 * Number2; 

                    Console.WriteLine("Multiplication is:{0}", Result); 

                    break; 

                case '4': 

                    Result = Number1 / Number2; 

                    Console.WriteLine("Division is:{0}", Result); 

                    break; 

                default: 

                    Console.WriteLine("Invalid Option"); 

                    break; 

            } 

            Console.ReadLine(); 

        } 

        }

    }

First Enter Two Numbers Respectively . Then Enter Operation Number To Perform Then Press Enter.

Output Will Be Like Below.

All The Best :)
