Keeping Derived Class Properties in a Collection

Question

I am in need of assistance, since I am stuck on a problem I have encountered. I have a List , List<Items> ItemList and I want to put some ContainerItems into that list, but when I do, all of the ContainerItems properties are gone and it turns into the baseclass of Items

class Items
{
    public Items()
    {

    }
    public string Name { get; set; }
    public int durability { get; set; }
}
class ContainerItems : Item
{
    public ContainersItem()
    {

    }
    public int maxItems { get; set; }
    public List<Items> ContainItems { get; set;}
}

Ideally I would like store all of the Items I'm making into a Dictionary<string,Items> . Is there anyway to store all the Items and ContainerItems together and keep their properties? thanks in advance!

Answer 1

Lets say you have your list of Items:

public List<Items> ContainItems { get; set }

And now you want to loop through them, but safely as not all of the members of the list will be a ContainerItems object:

foreach(var item in ContainItems)
{
    if(item is ContainerItems)
    {
        var containerItems = (ContainerItems)item;
    }
    else
    {
        //Otherwise deal with it as an Items object
    }
}

您将（1）将列表定义为List<ContainersItem>或（2）每次要使用特定于此类的字段或函数时，在ContainersItem列表的内容
