need help with a console menu

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

namespace Summative8.Menu
{
    internal abstract class ConsoleMenu : MenuItem
    {
        protected List<MenuItem> _menuItems = new List<MenuItem>();

        public bool IsActive { get; set; }

        public abstract void CreateMenu();

        public override void Select()
        {
            IsActive = true;
            do
            {
                CreateMenu();
                string output = $"{MenuText()}{Environment.NewLine}";
                int selection = ConsoleHelpers.GetIntegerInRange(1, _menuItems.Count, this.ToString()) - 1;
                _menuItems[selection].Select();
            } while (IsActive);
        }

        public override string ToString()
        {
            StringBuilder sb = new StringBuilder();
            sb.AppendLine(MenuText());
            for (int i = 0; i < _menuItems.Count; i++)
            {
                sb.AppendLine($"{i + 1}. {_menuItems[i].MenuText()}");
            }
            return sb.ToString();
        }
    }
}

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

namespace Summative8.Menu
{
    internal abstract class ConsoleMenu : MenuItem
    {
        protected List<MenuItem> _menuItems = new List<MenuItem>();

        public bool IsActive { get; set; }

        public abstract void CreateMenu();

        public override void Select()
        {
            IsActive = true;
            do
            {
                CreateMenu();
                string output = $"{MenuText()}{Environment.NewLine}";
                int selection = ConsoleHelpers.GetIntegerInRange(1, _menuItems.Count, this.ToString()) - 1;
                _menuItems[selection].Select();
            } while (IsActive);
        }

        public override string ToString()
        {
            StringBuilder sb = new StringBuilder();
            sb.AppendLine(MenuText());
            for (int i = 0; i < _menuItems.Count; i++)
            {
                sb.AppendLine($"{i + 1}. {_menuItems[i].MenuText()}");
            }
            return sb.ToString();
        }
    }
}

ive no errors in all the classes I have created other than this line, and I am struggling to see what I have done wrong

int selection = ConsoleHelpers.GetIntegerInRange(1, _menuItems.Count, this.ToString()) - 1;

int selection = ConsoleHelpers.GetIntegerInRange(1, _menuItems.Count, this.ToString()) - 1;

my lecturer always uses this consolehelper thing and i dont understand what it does or how i am supposed to use it

Jimmacle•9mo ago

it's not a standard thing it's either a nuget package or a class he wrote himself

jsOP•9mo ago

what could i use instead of that to get an int in range

Jimmacle•9mo ago

you could write your own helper method i don't know if that's what your lecturer intends though, did you ask them?

jsOP•9mo ago

idk i missed a couple of lectures cause of health issues and im trying to do stuff that i havent seen explained

Jimmacle•9mo ago

ask them or one of your classmates, we can't know what you're supposed to be doing here

jsOP•9mo ago

literally the most basic menu selecting a number from a list of options in a console menu

Angius•9mo ago

We have no way of knowing what ConsoleHelper does

jsOP•9mo ago

ohh

Angius•9mo ago

It seems like ConsoleHelpers.GetIntegerInRange() would be getting user input, parsing it to an integer, and checking if it's within the specified range

jsOP•9mo ago

yh its just a basic assignment with shape classes and editing shape properties etc

Jimmacle•9mo ago

right, but we don't know if your teacher expects you to write that class or if it was provided to you
