想請教一下這個是我在這裏看到

裏面這裏的model是怎麼的用法
   BlackCat target = new BlackCat()
    {
        ShipProduct = new Product
        {
            IsNeedCool = true,
            Name = "商品測試1",
            Size = new Size
            {
                Height = 10,
                Length = 30,
                Width = 20
            },
            Weight = 10
        }
    };
