Code for Scanner and Testing

We programmed the core functionality of the scanner in order to test it. First here are some diagrams of the code

Now here is the code for the classes

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DoorCardProofOfConcept
{
    class Program
    {
      
    
        static void Main(string[] args)
        {
            int exit = 1;
            while (exit != -1)
            {
                Console.WriteLine("Enter Card Number");
                string card = Console.ReadLine();
                Console.WriteLine("enter the Door number");
                string door = Console.ReadLine();
                Scanner s = new Scanner(card, door);
                Console.WriteLine(s.DoorState);
                Console.WriteLine("Enter -1 to Exit");
                exit = int.Parse(Console.ReadLine());
            }

           // Console.ReadKey();
