Adding An Item to Inventory, HELP!

Unity Engine

I just can’t seem to work out how to add Items to my Inventory when it already exists and the amount i’m adding go’s over the ‘maxStack’ amount?

Code:

List<Item> FilterItems(Item newitem){
		List<Item> result = new List<Item>();
		foreach(Item item in PlayerInventory.Inventory){//For 'Item' in Player's Inventory...
			if(item.ID == newitem.ID){//If newItem's ID = the loops current items ID... 
				if((item.currentStack + newitem.currentStack) < item.maxStack){//If the current stack + newItems stack is less than the maxStack...
					print ("Add");
					result.Add(item);
				} else{
					print ("Do something here!");
				}
			}
		}
		return result;
	}

public void AddItem(Item newItem){
		if(newItem.maxStack > 0){//If there are 1 or more stacks
			List<Item> stacks = FilterItems(newItem);
			if(stacks.Count > 0){//if there are more than 1 returned items
				stacks[0].currentStack += newItem.currentStack;
			} else {//when there is no stack yet or all stacks are full
				PlayerInventory.Inventory.Add(newItem);
			}
		} else{//Item is not stackable
			PlayerInventory.Inventory.Add(newItem);
		}
	}

Please ask if you need anything else?
