The problem now is that converting that plan into code. I'm editing and replacing code all over the place so I decide to start a new project and deal with the most necessary code I need.
Idea seems simple, but man...proved to be harder than I thought. I've been trying for the past hour and I lost in all this code..pretty much at my limit for today.

Is it better to just have an enum Items or separate all items into categories like I had above?

Removed a bunch of code and errors all over the place for now..Should I have enum Items in my hero class or should it be in a separate class and have my hero class use it when it's needed?

Alright, so I fixed up my Hero.cs and there seems to be no error. Now I just need to work on Store.cs, but how do I call on my Item class so all the items exist in current context?

Finally figured it out. That seemed like one big obstacle.
What I want to do now is figure out if I can define values like Cost, Type, bonuses, etc inside a x.cs and have it used in my store..not sure if that all made sense.

But like here's my ItemInfo.cs that my items inherit from.
using System;
using System.Collections.Generic;

namespace TextBasedGame
{
public enum Items
{
DevBeanie
}

public enum ItemType
{
Headgear
}

abstract class ItemInfo
{
protected ItemInfo(int cost, ItemType type)
{
Cost = cost;
Item = type;
}
public int Cost { get; protected set; }
public ItemType Item { get; protected set; }
}
}


Then have my actual item class
using System;
using System.Collections.Generic;

namespace TextBasedGame
{
class DevBeanie : ItemInfo
{
public DevBeanie()
: base(1, ItemType.Headgear)
{

}
}
}


Would it be possible to add things in like hero.bonusDefense +=10; and have it take away money?
Right now my shop is set up to check for the item then take away the gold.
case "DevBeanie":
case "devbeanie":
if (hero.items.Contains(Items.DevBeanie) == false)
{
if (hero.Gold >= 1)
{
hero.Gold -= 1;
hero.items.Add(Items.DevBeanie);
Console.WriteLine("Thank you, anything else you want?");
Console.ReadLine();
}

{
