将JSON反序列化回原始模型

Question

为什么这个JSON不会反序列化回序列化的模型？它将反序列化为Bar列表，​​但不反序列化为实现Bar列表的对象。

public class Bars : List<Bar>
{

}

public class Bar
{
    public decimal Open { get; set; }
    public decimal High { get; set; }
    public decimal Low { get; set; }
    public decimal Close { get; set; }
}

private void test()
{
    Bars bars = new Bars()
    {
        new Bar(){Open = 1.5269M, High = 1.6001M, Low = 1.4012M, Close = 1.5277M},
        new Bar(){Open = 1.5277M, High = 1.6003M, Low = 1.5276M, Close = 1.7008M},
        new Bar(){Open = 1.7008M, High = 1.9003M, Low = 1.4276M, Close = 1.60098M}
    };

    JavaScriptSerializer jss = new JavaScriptSerializer();

    string json = jss.Serialize(bars);

    //works
    var dsBars1 = jss.Deserialize<List<Bar>>(json);

    //fails
    var dsBars2 = jss.Deserialize<Bars>(json);

}

Answer 1

您可以使用Json.Net。下面的代码工作......

var json = JsonConvert.SerializeObject(bars);
var dsBars1 = JsonConvert.DeserializeObject<List<Bar>>(json);
var dsBars2 = JsonConvert.DeserializeObject<Bars>(json);
