// 创建属性ID

public int ID

{

get { return _ID; }

}

// 创建属性Name

public string Name

{

get { return _Name; }

}

// 创建属性Price

public decimal Price

{

get { return _Price; }

}

// 创建属性Quantity

public int Quantity

{

get { return _Quantity; }

set { _Quantity = value; }

}

// 创建类构造函数

public CartItem(int ID, string Name, decimal Price)

}
Session结合Hashtable也可以实现购物车。
