I have created an API that I am now attempting to access through another application. Even though I am using Newtonsoft.JSON to both serialize and deserialize the JSON, I am encountering a conversion error, with the following InnerException:
{"Could not cast or convert from System.String to System.Collections.Generic.List`1[MidamAPI.Models.ManagerDTO]."}
The following is the snippet that throws the error (in RESTFactory):
public List<T> Execute<T>(String endPoint) where T : new() {
RestClient client = new RestClient(BASE_URL);
IRestRequest req = new RestRequest(endPoint);
req.AddHeader("Authorization", "Bearer " + this._token);
var response = client.Execute(req).Content;
List<T> responseData = JsonConvert.DeserializeObject<List<T>>(response);
return responseData;
}
which is called here:
{
RegisterViewModel vm = new RegisterViewModel();
RESTFactory factory = new RESTFactory((String)Session["bearer"]);
vm.availableManager = factory.Execute<ManagerDTO>("managers");
vm.availableProperties = factory.Execute<PropertyDTO>("locations");
vm.availableTrainers = factory.Execute<TrainerDTO>("trainers");
return View(vm);
}
The information is coming from the following API controller action (in a separate application):
[LocalFilter]
[RoutePrefix("managers")]
public class ManagersController : ApiController
{
UnitOfWork worker = new UnitOfWork();
[Route("")]
public string Get()
{
IEnumerable<ManagerDTO> dtoList = Mapper.Map<List<Manager>, List<ManagerDTO>>(worker.ManagerRepo.Get().ToList());
foreach (ManagerDTO dto in dtoList)
{
Manager manager = worker.ManagerRepo.GetByID(dto.ID);
dto.Stores = (Mapper.Map<IEnumerable<Property>, IEnumerable<PropertyDTO>>(manager.Properties)).ToList();
}
return JsonConvert.SerializeObject(dtoList);
}
The DTOs are the same in both applications:
{
public class ManagerDTO
{
public int ID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public List<PropertyDTO> Stores { get; set; }
}
public class PropertyDTO
{
public int ID;
public string ShortName { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
public string Phone { get; set; }
public string Lat { get; set; }
public string Long { get; set; }
public string GooglePlaceID { get; set; }
public string PropertyNumber { get; set; }
public int ManagerID { get; set; }
public int TrainerID { get; set; }
public string ManagerName { get; set; }
public string ManagerEmail { get; set; }
public string TrainerEmail { get; set; }
}
I tried using the json2csharp tool with the response, and everything seems fine to my eyes:
public class Store
{
public int ID { get; set; }
public string ShortName { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
public string Phone { get; set; }
public string Lat { get; set; }
public string Long { get; set; }
public string GooglePlaceID { get; set; }
public string PropertyNumber { get; set; }
public int ManagerID { get; set; }
public int TrainerID { get; set; }
public string ManagerName { get; set; }
public string ManagerEmail { get; set; }
public object TrainerEmail { get; set; }
}
public class RootObject
{
public int ID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public List<Store> Stores { get; set; }
}
Any advice would be appreciated.
EDIT:
The RegisterViewModel class
public class RegisterViewModel
{
public RegistrationDTO regModel { get; set; }
public List<ManagerDTO> availableManager { get; set; }
public List<PropertyDTO> availableProperties { get; set; }
public List<TrainerDTO> availableTrainers { get; set; }
}
Make your controller Get() return type
IHttpActionResult
and return
Ok(dtoList);

I'm trying to consume a web API into Blazor but am struggling to extract certain information from the API
using System.Text.Json;
namespace CA3.Song
{
public class SongService : ISongService
{
private readonly HttpClient _httpClient;
const string _baseUrl = "https://genius-song-lyrics1.p.rapidapi.com/";

Configure();
var response = await _httpClient.GetAsync(_songEndpoint);
var response_outcome = response.EnsureSuccessStatusCode;
using var stream = await response.Content.ReadAsStreamAsync();
var dto = await JsonSerializer.DeserializeAsync<SongDto>(stream);
return dto.response.chart_items.Select(n => new SongItem { Artist = n.item.primary_artist, Title = n.item.primary_title, ReleaseDate = n.primary_release_date }).ToList().T ;

Above is the JSON file and I'm trying to extract the artist name, song title and release date from Item but it isn't in a list so I'm trying to find a way to extract this info using LINQ. Any help would be greatly appreciated !
I think you misinterpreted the declaration of the JSON. They are stored in an array Chart_Items[] chart_items thus you may use linq.
There are many ways to do this, I took advantage of named tuples in modern C# paired with linq.
Response r = new Response();//some resonse from api
var results = r.chart_items.Select(i => (i.item.artist_names, i.item.title, i.item.release_date_components)).ToList();
foreach(var result in results)
{
string artist_names = result.artist_names;
string title = result.title;
Release_Date_Components release_date_components = result.release_date_components;
}
I faced the problem: Cannot deserialize the current JSON object.
As follows:
public List<Track> Tracks { get; set; }
public async Task<List<Track>> GetTracking()

requests.Headers.TryAddWithoutValidation("accept", "application/json");
var response = await httpClient.SendAsync(requests);
using (HttpContent content = response.Content)
{
var jsonStr = content.ReadAsStringAsync().GetAwaiter().GetResult();
var res = JsonConvert.DeserializeObject<List<Track>>(jsonStr); //Get Error**
Tracks = res;
}
}
}
return Tracks;

As in my description. I get the error: I get the error: Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[XX. Models.Track]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
Even though I declared: public List events { get; set; }
Is the problem I have misunderstood the format of DeserializeObject. Looking forward to everyone's help. Thank
you have an object, not an array
var res = JsonConvert.DeserializeObject<Track>(jsonStr);
and fix class
public class Events
{
....
public List<DocumentReferencesMearsk> documentReferences { get; set; }
public TransportCallMaersk transportCall { get; set; }
}
Your model is incomplete and has typos. Assuming you have the correct versions of them.
You are doing:
var res = JsonConvert.DeserializeObject<List<Track>>(jsonStr);
which should be just:
var res = JsonConvert.DeserializeObject<Track>(jsonStr);
Your json doesn't have an array at the root level.
Full working sample:
void Main()
{
var res = JsonConvert.DeserializeObject<Track>(myJson);

I'm not sure what is causing this to happen. When debugging, I can step through each line, but when it hits the DeserializeObject line, the program doesn't do anything. I can no longer step over or do anything else with the program. No error messages are being thrown either.

As mentioned in a comment your class definition doesn't seem to match the JSON response, assuming you're using Visual Studio it's probably worth opening Debug / Windows / Exception Settings and make sure "Common Language Runtime Exceptions" is checked. Sometimes I've found stepping over in multi-threaded apps can produce unusual results after an exception.
When I pasted your code into LINQPad I got errors on several members you've defined as List<string> when the underlying type is more complex. What I normally do to avoid those errors is copy the raw json from a browser window to the clipboard and with a CS file open in Visual Studio do an Edit / Paste Special / Paste JSON as classes to automatically create the classes. After doing that I got the following that deserialized the data fine:
async Task Main()
{
await LookupMonsterStats("aboleth");
}
public async Task LookupMonsterStats(string name)

In the next step I want to pass values in this created class. After that by serializing object of this class I want to pass that serialized Json to one service I am consuming. I have tried below by referring Turn C# object into a JSON string in .NET 4. But getting error Object reference not set to an instance of an object.
RootObject rootObject = new RootObject();
rootObject.saveExistingRetailCustomerReq.reqHdr.consumerContext.applicationId = "CRM";
var jsonData = JsonConvert.SerializeObject(rootObject);
If I am doing anything wrong then I would appreciate if anyone could guide me in this process.
You need create all objects not only RootObject.
RootObject rootObject = new RootObject();
rootObject.saveExistingRetailCustomerReq = new SaveExistingRetailCustomerReq();
rootObject.saveExistingRetailCustomerReq.reqHdr = new ReqHdr();
rootObject.saveExistingRetailCustomerReq.reqHdr.consumerContext = new ConsumerContext();
rootObject.saveExistingRetailCustomerReq.reqHdr.consumerContext.applicationId = "CRM";
var jsonData = JsonConvert.SerializeObject(rootObject);
im trying to deserialize a Json that i get from a webservice Like so:
Uri urlJson = new Uri("http://optimizingconcepts.com/staging/cartuxa/system/json_request.php?lang=pt");
var client = new HttpClient();
HttpResponseMessage response = await client.GetAsync(urlJson);
var jsonString = await response.Content.ReadAsStringAsync();
the Json i get is this:http://paste2.org/MpYJd8kk
I then do this to get the JsonObject:
JsonObject root = Windows.Data.Json.JsonValue.Parse(jsonString).GetObject();
What i want to know, is the correct way of saving each object from json to a list
so the objects from "home" would be in a List, the objects from "artigos" would go to a List and so on.
Using Json.Net, it can be done as follows
Uri urlJson = new Uri("http://optimizingconcepts.com/staging/cartuxa/system/json_request.php?lang=pt");
var client = new HttpClient();
var json = await client.GetStringAsync(urlJson);
var obj = JsonConvert.DeserializeObject<Cartuxa.RootObject>(json);
I used http://json2csharp.com/ to generate below classes.
