试图将 json 字符串反序列化为列表。Json 字符串不为空。但在反序列化后，列表返回 0 个项目。

这是我的课。

 [Serializable]
    public class Products : GenericItem
    {
        public List<string> Images { get; set; }
        public double Price { get; set; }
        public double SalePrice { get; set; }

        public bool OnSale
        {
            get { return (SalePrice < Price); }
        }

        public string Description { get; set; }

        public GenericItem Brand { get; set; }

        public List<GenericItem> Shops { get; set; }

        public string ProductCode { get; set; }

        public Colour Colour { get; set; }
    }

    [Serializable]
    public class Colour : GenericItem
    {
        public string Code { get; set; }
    }

    [Serializable]
    public class GenericItem
    {
        public string Name { get; set; }

        public string Permalink { get; set; }
    }

这是我的 json 字符串。

"{\"Products\":[{\"_id\":\"515c151f7be95925d4ee794d\",\"Name\":\"CAT Formation Steel Toe - Boots  BLACK\",\"Description\":\"CAT Formation Steel Toe Boots With heavy-duty hardwearing uppers, high grip rubber outsoles and a steel toe cap, these CAT Formation Steel Toe Boots are perfect for work. CAT Formation Steel Toe Boots are ankle length and fasten with strong laces for a secure fit. The boots are available in black and have a casual multi-panelled trainer-style appearance, as well as CAT branding on the tongue and heel.\",\"ProductCode\":\"D0073\",\"Images\":[\"18000.jpg\",\"18001.jpg\",\"18002.jpg\"],\"Brand\":{\"_id\":\"5142ca0c7be95917acce7755\",\"Name\":\"CAT\",\"Permalink\":\"cat-footwear\"},\"Shops\":[{\"_id\":\"5142ca237be95917acce7999\",\"Name\":\"Mens\",\"Styles\":null,\"Permalink\":\"Mens\"}],\"Permalink\":\"cat-formation-steel-toe-boots-black\",\"Price\":89.99,\"SalePrice\":89.99}]}"

这就是我反序列化 json 字符串的方式。

 var jss = new JavaScriptSerializer();
            jss.MaxJsonLength = Int32.MaxValue;
            var results = jss.Deserialize<List<Products>>(json);

列表总是返回 0 个结果。

有人可以帮助我。

您的 JSON 不是列表，而是具有属性 Products 的对象，即列表。

您可以将其反序列化为：

public class MyClass
{
    public List<Products> Products { get; set; }
}
...

jss.Deserialize<MyClass>(json);
