[SOURCE][C#] Console Menu - DragonHunter - Nov 7, 2010

Hey guys, this is a simple Console Menu i've made yesterday
have fun with the code 😎

Code
public class CMenu
    {
  private SortedList<int, string[]> menu;
  public int CurrentMenu = 0;
  public int SelectedIndex = 0;
  private Thread KeyHandlerThread;
  public ConsoleKeyInfo KeyPressed;
  private ConsoleColor SelectColor;
  private ConsoleColor NonSelectColor;

  public CMenu()
  {
    menu = new SortedList<int,string[]>();
    KeyHandlerThread = new Thread(new ThreadStart(KeyPressHandler));
    KeyHandlerThread.Start();
    SelectColor = ConsoleColor.Green;
    NonSelectColor = ConsoleColor.Gray;
  }

  public void Refresh()
  {
    Console.Clear();
    Console.WriteLine("");
    for(int y = 0; y < menu[CurrentMenu].Length; y++)
    {
    if(SelectedIndex == y)
    Console.ForegroundColor = SelectColor;
    else
    Console.ForegroundColor = NonSelectColor;

    Console.Write(menu[CurrentMenu][y].ToString().PadLeft(12));
    Console.ResetColor();
    }
    Console.WriteLine("");
    Console.WriteLine("");
  }

  private void KeyPressHandler()
  {
    while(true)
    {
    KeyPressed = Console.ReadKey();
    if(KeyPressed.Key == ConsoleKey.RightArrow)
    {
    if(SelectedIndex < menu[CurrentMenu].Length - 1)
    SelectedIndex++;
    }
    else if(KeyPressed.Key == ConsoleKey.LeftArrow)
    {
    if(SelectedIndex > 0)
    SelectedIndex--;
    }
    }
  }

  public void AddMenu(int index)
  {
    menu.Add(index, new string[] { });
  }

  public void AddSubMenu(int index, string[] SubMenu)
  {
    menu[index] = SubMenu;
  }
    }

Usage:
Code
CMenu menu = new CMenu();
    menu.AddMenu(0); //create new menu with ID 0
    menu.AddSubMenu(0, new string[] { "Goto Menu2", "Goto Menu2" });

    //Second menu
    menu.AddMenu(1); //create new menu with ID 1
    menu.AddSubMenu(1, new string[] { "Goto Menu1", "[Back]" });

    while(true)
    {
    Thread.Sleep(50);
    menu.Refresh();//lets refresh the menu...

    //put here ur own code to show stuff at the console...

    switch (menu.CurrentMenu)
    {
    case 0:
    Console.WriteLine("-- MENU 1 --");
    switch (menu.SelectedIndex)
    {
    case 0:
    if(menu.KeyPressed.Key == ConsoleKey.Enter)
    {
    menu.CurrentMenu = 1;
    menu.KeyPressed = new ConsoleKeyInfo();
    }
    Console.WriteLine("Hello, This Console menu is created by DragonHunter");
    break;
    case 1:
    if(menu.KeyPressed.Key == ConsoleKey.Enter)
    {
    menu.CurrentMenu = 1;
    menu.KeyPressed = new ConsoleKeyInfo();
    }
    Console.WriteLine("Please leave the credits when ull share it somewhere else");
    break;
    }
    break;
    case 1:
    Console.WriteLine("-- MENU 2 --");
    switch (menu.SelectedIndex)
    {
    case 0:
    if (menu.KeyPressed.Key == ConsoleKey.Enter)
    {
    menu.CurrentMenu = 0;
    menu.KeyPressed = new ConsoleKeyInfo();
    }
    Console.WriteLine("This will let us navigate back to menu1");
    break;
    case 1:
    if (menu.KeyPressed.Key == ConsoleKey.Enter)
    {
    menu.CurrentMenu--; //easy ha ?
    menu.KeyPressed = new ConsoleKeyInfo();
    }
    Console.WriteLine("let us navigate back to our first menu :P");
    break;
    }
    break;
    }
    }

Wow man. This is a brilliant idea!

I added this to my compilation thread of C#. This can be used for MANY Things.
