Json.net map dynamic property to a fixed one [duplicate]



This question already has an answer here:



QuickBooks Online uses for their API the following response:



"QueryResponse":
"Customer": [

"GivenName": "Test"
,

"GivenName": "Test 2"

],
"startPosition": 1,
"maxResults": 2
,
"time": "2018-08-11T16:12:10.808-07:00"



I'm trying to create a C# model from this:


public class QueryResponseRoot<T> where T : IQuickbooksBaseEntity

[JsonProperty("QueryResponse")]
public QueryResponse<T> QueryResponse get; set;

[JsonProperty("time", Required = Required.Always)]
public DateTimeOffset Time get; set;


public class QueryResponse<T> where T : IQuickbooksBaseEntity

[JsonProperty, JsonConverter(typeof(QuickbooksResponseConverter))]
public IList<T> Results get; set;

[JsonProperty("startPosition")]
public Int64 StartPositions get; set;

[JsonProperty("maxResults")]
public Int64 MaxResults get; set;



The API has multiple entities which are all defined with the IQuickbooksBaseEntity interface.


IQuickbooksBaseEntity



The problem is that if you get Customers it will return Customer as a property on the QueryResponse object, but if you get something else like Accounts the response looks like this:


Customers


Customer


QueryResponse


Accounts



"QueryResponse":
"Account": [

"Name": "Accounts Payable (A/P)"

],
"startPosition": 1,
"maxResults": 90
,
"time": "2018-08-11T16:14:55.309-07:00"



How can I map the property Customer or Account or any other one from a known list to the Results property in my model?


Customer


Account


Results



Import to know (probably) is that I do know when I call the API which property will be returned to me (i.e. Customer or Account).



Now I'm solving it directly in code, but I'm not sure if casting it dynamic has large performance issues:


var resultObjectJson = JsonConvert.DeserializeObject<dynamic>(body);

var entityName = typeof(T).Name;

var maxResults = (Int64) resultObjectJson.QueryResponse.maxResults;
var startPositions = (Int64) resultObjectJson.QueryResponse.startPosition;
var results = ((JArray) resultObjectJson.QueryResponse[entityName]).ToObject<List<T>>();

var resultRoot = new QueryResponseRoot<T>

QueryResponse = new QueryResponse<T>

MaxResults = maxResults,
StartPositions = startPositions,
Results = results

;

return resultRoot.QueryResponse;



This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.





Looks like a duplicate of Json.NET getting generic property types name on serialization? and/or How to get the name of <T> from generic type and pass it into JsonProperty()?. Agree?

<T>





@dbc I'm not 100% positive but it looks like they are trying to do serializing, I need to be able to deserialize.

Both answers use a custom contract resolver and so should work for both serialization and deserialization.

Did you give either answer a try?

I'm not very familias with custom contracts, but I didn't see how you can re-map multiple properties to one without having an instance of the result yet?
