A get or set accessor required (Console Application)

[Erendar]

{ and } missing at some places.
Console.ReadLine()); returns a string, so you need to parse it before putting it inside an integer
static void Main(); if you put ; here it means that you've finished implementing the function

namespace ConsoleApplication2
{
    class Program
    {
        
        static void Main()
        {
            int ID;
            Console.WriteLine("Enter Username");
            string Name = Console.ReadLine();
            if (Name.ToLower() == "administrator")
            {

                Console.WriteLine("Welcome System Administrator. Enter your password.");
                if (Console.ReadLine() == "root")
                {
                    Console.WriteLine("System Administrator logon successful!");
                }
                else
                {
                    Console.WriteLine("Invalid password. Please log on as guest.");
                }
            }
            else
            {
                Console.WriteLine("Welcome System User. Please enter the confirmation code to confirm you are a user of the mainframe.");
                if (Console.ReadLine() == "ibmmainframe7")
                {
                    Console.WriteLine("Welcome System User. Please enter your ID");
                    ID = int.Parse(Console.ReadLine());
                    Console.WriteLine("Welcome system user # " + ID.ToString());
                }
                else
                {
                    Console.WriteLine("Welcome System Guest!");
                }

            }


            Console.ReadLine();

        }
    }
