如何反序列化动态Json对象

Question

我当前从我的api收到以下JSON响应：

{"Lastname":["ERRLASTNAMEEMPTY"],"Firstname":["ERRFIRSTNAMEEMPTY"]}

请注意，上面的响应是动态的，即有时我可以使用FirstName，有时使用LastName，有时同时使用两者。此响应基于对数据的验证。

我的问题是，是否有一种方法可以使用JsonSerializer反序列化此响应。DeSerialize？

我试过这样使用它，但它不起作用：

var errorBody = JsonSerializer.Deserialize<dynamic>(body, serializerOptions);

Answer 1

JsonSerializer.Deserialize<Dictionary<string,string[]>>(body, serializerOptions);

Answer 2

您可以使用JObject处理动态JSON对象，如下所示：

var data = JObject.Parse(body);

稍后，您可以使用data["Lastname"]?.Value<string>();之类的方式访问值。

Answer 3

JsonSerializer.Deserialize<ExpandoObject>(body, serializerOptions);

Answer 4

// introduce a dynamic object from a string :
// {"UrlCheckId":581,"Request":{"JobId":"a531775f-be19-4c78-9717-94aa051f6b23","AuditId":"b05016f5-51c9-48ba-abcc-ec16251439e5","AlertDefinitionId":108,"JobCreated":"2022-05-20T07:09:56.236656+01:00","UrlJobId":0,"BatchJobId":"e46b9454-2f90-407d-9243-c0647cf6502d"},"JobCreated":"2022-05-20T07:10:21.4097268+01:00"}
// ...The UrlCheckId is an int primitive and Request is our UrlCheckJobRequest object.
dynamic msg = JsonConvert.DeserializeObject(message);
// to access an int (primitive) property:
int id = msg.UrlCheckId;
// to access an object, you might have to serialize the request into a string first...
var r = JsonConvert.SerializeObject(msg.Request);
// ... and then deserialize into an object
UrlCheckJobRequest request = JsonConvert.DeserializeObject<UrlCheckJobRequest>(r);
