How do I iterate through a list containing objects? c#

Question

I created a list that stores objects from another class. The objects stored in my list each have a name and an integer. I want to know if I can iterate through my list and display the name of each object. If I change the type of i to VAR or Dynamic it says its out of range.

    public List<InventoryHandling> Inventory = new List<InventoryHandling>();

    public void inventorySelect()
    {
        Inventory[0] = new InventoryHandling("Potion", 4);

        foreach(int i in Inventory)
        {
            Console.WriteLine(Inventory[i].Name);
        }
    }

Answer 1

To start, this line is wrong:

Inventory[0] = new InventoryHandling("Potion", 4);

The problem is the [0] index refers to the first item in the list, but (presumably) at this point the list doesn't have any space yet. The position at index [0] doesn't exist, and C# does not allow you to append to a list by assigning to the next index. Instead, when you want to add new items to a list, you should call it's .Add() method:

Inventory.Add(new InventoryHandling("Potion", 4));

Now we have a list with some content, we can talk about how to iterate it. And just like appending, you don't use indexes with a foreach loop:

foreach(InventoryHandling ih in Inventory)
{
    Console.WriteLine(ih.Name);
}

If you really want to use indexes, you can do it with a for loop:

for(int i = 0; i < Inventory.Length; i++)
{
    Console.WriteLine(Inventory[i].Name);
}
