Get_ItemId on object ItemInstance

Hello all,

I want get the id Item, thats it's logical, it's the name of this topic
In ItemInstance i have see one function get_Item(), he return one object of type : Assets.Scripts.Core.IItem
And this Object (Assets.Scripts.Core.IItem) contain a function get_ItemId() (return (int))
I want take this int in get_ItemId.

My variable test is a ItemInstance not empty
int id = test.get_Item().get_ItemId();
I have this message.
`Assets.Scripts.Core.IItem.ItemId.get': cannot explicitly call operator or accessor.
I don't know why.

Sorry for my bad English.
Thank you in advance.

 

Here's an example from one of my works in progress.

Code:

            //Retrieve the players inventory
            PlayerInventory inventory = curPlayer.session.WorldPlayerEntity.GetComponent<PlayerInventory>();            //Get the inventory contents
            var invContents = inventory.Items;            //Loop through each item in the inventory
            for (var i = 0; i < inventory.Items.Length; i++)
            {
 
                PrintWarning(invContents[i].Item.ItemId) + "");
            }

Could you tell me more specifically what you're trying to do, maybe I can post more relevant examples.
