C# adding items to List

Question

I am trying to add items to a list using for the following;

public class Reason
{
    [JsonProperty("code")]
    public int Code { get; internal set; }
}

public class Item
{
    [JsonProperty("Id")]
    public int Id { get; set; }

    [JsonProperty("quantity")]
    public int quantity { get; set; }

    [JsonProperty("reason")]
    public Reason reason { get; set; } = new Reason();
}

public class RootObject
{
    [JsonProperty("dropOff")]
    public DropOff dropOff { get; set; } = new DropOff();

    [JsonProperty("providerId")]
    public int providerId { get; set; }

    [JsonProperty("orderReference")]
    public string orderReference { get; set; }

    [JsonProperty("returnMethodId")]
    public int returnMethodId { get; set; }

    [JsonProperty("items")]
    public List<Item> items { get; set; } = new List<Item>();
}


root.items.Add(new Item { Id = 8675072, quantity = 1, Reason.Code = 2  });

I am getting the following error when i am trying to add the Reason.Code,

An Object Reference is required for the non-field, method or property.

Where would i need to initialise to add Reason.Code to the list?

Can you show where you initialize `root` – Sean Mar 11 '20 at 11:22 — Sean, Mar 11 '20 at 11:22
Are you trying to add items to `root` outside of classes? – SᴇM Mar 11 '20 at 11:26 — SᴇM, Mar 11 '20 at 11:26

root.items.Add(new Item { Id = 8675072, quantity = 1, reason = { Code = 2  }})

How is this `= { SomeProperty = value }` part is called? It looks like property initializer, but I was sure it can only be used with `new`. – Sinatr Mar 11 '20 at 11:36
