[NonSerialized]
public decimal total;
public ShoppingCartItem(int _productId, decimal _price, int _quantity)

productId = _productId;
price = _price;

total = price * quantity;
}
protected ShoppingCartItem(SerializationInfo info, StreamingContext context)

price = info.GetDecimal("Price");
quantity = info.GetInt32("Quantity");
total = price * quantity;
}
