初始化list链表

//ProductAttribute有三个属性
class ProductAttribute
    {
        string name = "";
        float price = 0;
        int number = 0;

        public ProductAttribute(string name, float price, int number) 
        {
            this.name = name;
            this.price = price;
            this.number = number;
        }
//对list进行初始化
List<ProductAttribute> productList;
productList = new List<ProductAttribute>()
            {
                new ProductAttribute("apple",(float)1.11,0),
                new ProductAttribute("banana",(float)2.22,0),
                new ProductAttribute("orange",(float)3.33,0),
                new ProductAttribute("pear",(float)4.44,0),
                new ProductAttribute("lemon",(float)5.55,0),
                new ProductAttribute("mango",(float)6.66,0),
                new ProductAttribute("grape",(float)7.77,0),
                new ProductAttribute("coconut",(float)8.88,0),
                new ProductAttribute("litchi",(float)9.99,0)

            };
