Hi. I have at school a program in C# console application to create 2 menus. I created the first one, i can choose any option i want, the point is the first option is to log in. if success i need to go into 2nd menu. but when i go into 2nd menu i can't choose any option. here is my code:

The one that is commented is the one that doesnt work.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;

namespace Unit18_CW_ID12389
{
class Program
{
static void Main(string[] args)
{

int option = 0;
//int option1 = 0;
option = DisplayMenu();

if (option == 1)
{
//call SignIn() method
SignIn();

}
else if (option == 2)
{
//call SignUp() method
Signup();

}
else if (option == 3)
{
//exit
Environment.Exit(0);
}
else
{
Console.WriteLine("Error,choose another option from the menu!");
}
while (option <= 3) ;
DisplayMenu();

/* option1 = MainMenu();
if (option1 == 1)
{
//Read previous history method
Console.WriteLine("Hello");

}
else if (option1 == 2)
{
//Enter new details
}
else if (option1 == 3)
{
//Show overall progress

}
else if (option1 == 4)
{
//EXIT
Environment.Exit(0);
}
else
{
Console.WriteLine("Error,choose another option from the menu!");
}
option1 = MainMenu();
while (option1 <= 4) ;
MainMenu();

}

{
int x = 0;
Console.WriteLine("\n\n\n\n\n");
Console.WriteLine("\t\t\t\t[1] Sign in");
Console.WriteLine("\t\t\t\t[2] Sign up");
Console.WriteLine("\t\t\t\t[3] Exit");
Console.WriteLine("Select from the menu:");

x = int.Parse(Console.ReadLine());
return x;
}

#region Code to sign up

string userID,password;
Console.WriteLine("New Username: ");
