Question

I’ve made a switch-case where I use the up arrow key, down arrow key and enter key. However I can’t think of how to put code into my enter case in which I can choose an option.

public static void entries()
    {
        keyPressed = Console.ReadKey(true);
        switch (keyPressed.Key)
        {

            case ConsoleKey.DownArrow:
                if (keyPressed.Key.ToString() == "DownArrow")// selects the curitem when the down arrow key is pressed
                {
                    curItem++;
                    if (curItem > menuItems.Length - 1) curItem = 0;
                }
                break;
            case ConsoleKey.UpArrow:
                if (keyPressed.Key.ToString() == "UpArrow")// selects the curitem when the up arrow key is pressed
                {
                    curItem--;
                    if (curItem < 0) curItem = Convert.ToInt16(menuItems.Length - 1);

                }
                break;
            case ConsoleKey.Enter:
                if (keyPressed.Key.ToString() == "Enter")// when enter is pressed it will go to one of the choices 
                {

                }
                break;
            default:
                break;
        }
    }

Answer 1

Your idea about nesting if statements is correct, or having another switch. I would probably re-factor this into another function though:

case ConsoleKey.Enter:
   chooseOption(curItem);
   break;

…

void chooseOption(int item)
{
   switch(item)
   {
      case 1:
        //Do item 1
        break;
      case 2:
        //Do item 2
        break;
      case 3:
        //Do item 3
        break;
   }
}
