Deserialize JSON to list with unknown object name in C#

I want to deserialize following JSON.

The problem is that the objects "ANDE" & "DAR" can change.

Means the objects are unknown and change depending on the JSON i wanna deserialize.

About 8000 different objects (ANDE, DAR, ...) need to be deserialized.

"ANDE":
"chart":[
"date":"20180914","minute":"09:30","date":"20180914","minute":"13:30"],
"DAR":
"chart":[
"date":"20180914","minute":"09:30","date":"20180914","minute":"13:30"]


I get the data by HTTP response and want to put into a List:

HttpResponseMessage response = client.GetAsync(API_PATH).GetAwaiter().GetResult();
List historicalDataList = response.Content.ReadAsAsync<List<HistoricalDataResponse>>().GetAwaiter().GetResult();


The HistoricalDataResponse class looks like:

public class HistoricalDataResponse

public string date get; set;
public string minute get; set;



How can i deserialize this kind of JSON with unknown objects in C#?
Any help is highly appreciated.

Dictionary<string, xxx>

Then you should use a dynamic variable:

dynamic ReturnValue = JsonConvert.DeserializeObject(jsonstring);


note that as in dynamic objects, properties are determined after being assigned in runtime, so you will not get a drop down menu in design time, and also as its properties are unknown in design time, and property you test in design time even if its not correct, you wont get an error, and you will get the error in runtime when it is assigned.

dynamic ReturnValue = JsonConvert.DeserializeObject(jsonstring);

try

var a = ReturnValue.ANDE; // will work if it has ANDE property.
// do what you would do with ANDE

catch
try

var a = ReturnValue.DAR; // will work if it has DAR property.
// do what you would do with DAR

catch


Use a dictionary with string as key type :

void Main()

var client = new HttpClient();
HttpResponseMessage response = client.GetAsync("url").GetAwaiter().GetResult();
var json = response.Content.ReadAsStringAsync().GetAwaiter().GetResult();

var result = JsonConvert.DeserializeObject<Dictionary<string, DateResponse>>(json);
foreach (var element in result)

var key = element.Key; // ANDE
foreach (var item in element.Value.Chart)

var date = item.date;
var minute = item.minute;





public class DateResponse
public List<HistoricalDataResponse> Chart get; set;


public class HistoricalDataResponse

public string date get; set;
public string minute get; set;



HttpResponseMessage response = client.GetAsync(IEXTrading_API_PATH).GetAwaiter().GetResult();

DeserializeObject

ReadAsAsync

var result = response.Content.ReadAsAsync<Dictionary<string, DateResponse>>().GetAwaiter().GetResult();
