c#, printing items in list returns empty when list.add(Console.ReadLine)

Question

The console doesn't write the items in the list. I am trying to add input from user to a list then write to the screen. So once i add input to the list i would want it to print to the screen.

ArrayList list = new ArrayList();

 switch (userInput)
        {

            case "Add":
                {
                    Console.WriteLine("Enter Fullname: ");
                    Console.ReadLine();
                    list.Add(Console.ReadLine());

                    display();
                    break;
                }


            case "List":
                {

                    foreach (string item in list)
                    {

                        Console.WriteLine(item);
                    }
                    display();
                    break;
                }

        }

Too many calls to Console.Readline in case of "Add" – Steve Sep 24 '16 at 20:31 — Steve, Sep 24 '16 at 20:31

You need to assign to a variable and then add

string line = Console.ReadLine();
list.Add(line);

When you write:

ArrayList list = new ArrayList();

you delete all the elements in the ArrayList.

You didn't post how do you get to the "List" section after insertion the elements...

also you sholud delete the first

Console.ReadLine();

This is to create a new list. Then i add elements to list. – eyedfox Sep 25 '16 at 17:13
But how do you enter to the List section? – Moshe D Sep 25 '16 at 18:29
Case "List" shows how to view each item in the list – eyedfox Sep 25 '16 at 23:13
But after you enter Add, you adding an element to the list, and after that becuase the "Break" statment you exit from the switch-case... – Moshe D Sep 26 '16 at 10:05
