System.Text.JSON不会反序列化Newtonsoft的功能

问题描述

我有一个json，新的System.Text.Json.JsonSerializer.Deserialize<T>(json_data)用正确数量的元素序列化为List<T>，但是里面的对象的所有值都为null或0

I have a json that the new System.Text.Json.JsonSerializer.Deserialize<T>(json_data) serialize as List<T> with the correct numbers of elements, but then the objects inside have all the values null or 0

与Newtonsoft.Json.JsonConvert.DeserializeObject<T>(json_data)相同的json已正确填充.

Same json with Newtonsoft.Json.JsonConvert.DeserializeObject<T>(json_data) is correctly filled.

班级:

public class SensorValue
    {
        public string StationCode { get; set; }
        public string SensorCode { get; set; }
        public string SensorNameIt { get; set; }
        public string SensorNameDe { get; set; }
        public string SensorNameLd { get; set; }
        public string SensorUnitMeasure { get; set; }
        public DateTime SamplingDateTime { get; set; }
        public Decimal SamplingValue { get; set; }
    }

推荐答案

System.Text.Json解串器的默认行为是将属性匹配为区分大小写.您需要传递告诉它与大小写无关的选项:

The default behavior of the System.Text.Json deserializer is to match properties as case sensitive. You need to pass options telling it to match case insensitive:

using System.Text.Json;

JsonSerializer.Deserialize<T>(json_data, new JsonSerializerOptions
{
    PropertyNameCaseInsensitive = true
});
