Newton -反序列化对象时意外的令牌

Question

反序列化对象时意外的令牌:PropertyName。路径的出货量[0]。ShipmentItems'，第24行，第28位。

希望有人能帮助或指导我为什么我遇到这个错误时，试图反序列化对象。尽管验证了从restAPI返回的JSON格式正确且有效，但错误仍然存在。我不完全确定我在这里做错了什么或遗漏了什么，任何帮助都会非常感激。

代码部分的片段它是如何被反序列化的

string json = await response.Content.ReadAsStringAsync();
RootObject root = JsonConvert.DeserializeObject<RootObject>(json);

Answer 1

您需要将这些属性更改为nullable，因为它们在json字符串中具有空值。如果json字符串

中不能为空，那么检查另一个不可为空属性也是有意义的

[JsonProperty("residential")]
public bool? Residential { get; set; }
.....
[JsonProperty("weight")]
public double? Weight { get; set; }
