I'm trying to make an application that can show local TV guide trough JSON rest api C #, but has some problems with deserialization of my Json response.
i'm only intresest in the array NOW in my json call and i do not own the api service.
I get this error message:
An exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.DLL but was not handled in user code
Additional information: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[TDC_Play_TV_Mobil.superclass2+Now]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'now', line 1, position 7.
My function:
private HttpClient client;
public async Task<List<superclass2.Now>> GetComments()
{
client = new HttpClient();
var response = await client.GetAsync(new Uri("http://api.yousee.tv/rest/tvguide/nowandnext/"));
if (response.IsSuccessStatusCode)
{
string json = await response.Content.ReadAsStringAsync();
System.Diagnostics.Debug.WriteLine(json);
var task = Task.Factory.StartNew(() => JsonConvert.DeserializeObject<List<superclass2.Now>>(json));
var value = await task;
// List<superclass2.Now> comments = Newtonsoft.Json.JsonConvert.DeserializeObject<List<superclass2.Now>>(await json);
System.Diagnostics.Debug.WriteLine("Comments er lavet");
return value;

Your JSON isn't a List<superclass2.Now>, it's a superclass2.RootObject. So you need to do something like:
public async Task<List<superclass2.Now>> GetComments()
{
client = new HttpClient();
var response = await client.GetAsync(new Uri("http://api.yousee.tv/rest/tvguide/nowandnext/"));
if (response.IsSuccessStatusCode)
{
string json = await response.Content.ReadAsStringAsync();
System.Diagnostics.Debug.WriteLine(json);
var task = Task.Factory.StartNew(() => JsonConvert.DeserializeObject<superclass2.RootObject>(json));
var value = await task;
System.Diagnostics.Debug.WriteLine("Comments er lavet");
return (value == null ? null : value.now);
}
else
{
throw new Exception("Errorhandling message");
}
}
Agree with Jon Skeet it would be nicer to eliminate the nesting of classes, purely for improved readability. If you need these classes to exist only in a specific scope, it is better to use nested namespaces. They aren't causing your bug, however.

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 ;

_httpClient.DefaultRequestHeaders.Add("X-RapidAPI-Host", _host);
_httpClient.DefaultRequestHeaders.Add("X-Rapid-Key", _key);

The issue is on the return statement using LINQ.

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()
{
using (var httpClient = new HttpClient())
{
using (var requests = new HttpRequestMessage(new HttpMethod("GET"), "urlxxxxxxxx..."))
{
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
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);

EDIT: Result is something like:
I'm trying to turn the string result below in the first line of code into an object of type "Root.cs". I have "Root.cs" class set up in my Visual Studio 2019 "solution" with proper classes set up to turn the string result into the object.
This line of code works fine to get me the string I need:
var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;
Here's the contents of the string "result":
{"sections":[{"id":"Building_Configuration","name":"Building_Configuration","sections":[{"id":"B uilding_Configuration.Parameters_SP","name":"Building_Configuration.Parameters_SP","sectio ns":[],"variables":[{"id":"Building_Configuration.Parameters_SP.fixtureStrategy_SP","name":"Bui lding_Configuration.Parameters_SP.fixtureStrategy_SP","valueType":"String","distinctValueCou nt":3.0,"allowMultipleAssignments":false,"values":[{"name":"ETA","value":"ETA","properties":[{ "id":"fullyqualifiedname","value":"ETA","type":"String"},{"id":"name","value":"ETA","type":"Stri ng"}],"type":"SingletonValue","assigned":"byDefault","incompatible":false},{"name":"ETD","valu e":"ETD","properties":[{"id":"fullyqualifiedname","value":"ETD","type":"String"},{"id":"name","v alue":"ETD","type":"String"}],"type":"SingletonValue","incompatible":false},{"name":"ETA/ETD", "value":"ETA/ETD","properties":[{"id":"fullyqualifiedname","value":"ETA/ETD","type":"String"},{ "id":"name","value":"ETA/ETD","type":"String"}],"type":"SingletonValue","incompatible":false}],"

My "result" and my "Root.cs" class are each larger than the 30,000 characters limit here. So, I've had to only post a portion of my string "result" and my "Root.cs" class. I'm trying to simplify this question. Please forgive me while I learn how to use this...
Answer: I was making the newbie mistake of trying to return a string that I picked out of a "Root.cs" Model class as a Root object. I had the return type of the method set to Root instead of string. Upon changing the return type to string, that part of my solution works fine.
It works fine like this:
public string CreateExecPost(FormData person2){
var payload = new StringContent(newPost, Encoding.UTF8, "application/json");
var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;//result is already in JSON
Root MyObject = JsonConvert.DeserializeObject<Root>(result);
//return MyObject.language; //WORKS
return MyObject.language;
}
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.
[Command("stats")]
public async Task LookupMonsterStats(CommandContext ctx, string name)
{
string monstersUri = "https://www.dnd5eapi.co/api/monsters/";
var formatted = name.Replace(" ", "-");
string apiResponse = string.Empty;
using (var httpClient = new HttpClient())
{
using (var response = await httpClient.GetAsync(monstersUri + formatted))
{
apiResponse = await response.Content.ReadAsStringAsync();
var monster = JsonConvert.DeserializeObject<Monster>(apiResponse);
}
}
await ctx.Channel.SendMessageAsync(apiResponse).ConfigureAwait(false);

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)
{
string monstersUri = "https://www.dnd5eapi.co/api/monsters/";
var formatted = name.Replace(" ", "-");
string apiResponse = string.Empty;
using (var httpClient = new HttpClient())
{
using (var response = await httpClient.GetAsync(monstersUri + formatted))
{
apiResponse = await response.Content.ReadAsStringAsync();
var monster = JsonConvert.DeserializeObject<Monster>(apiResponse);
monster.Dump();
}

I have this json
and i want to deserialize it so I can get each object's value for example:
"icon_url": "-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXH5ApeO4YmlhxYQknCRvCo04DEVlxkKgpouLWzKjhzw8zFdC5K092kl5SClMj3PLXFhGpC_Pp8j-3I4IG7i1Hn_UI-Nmj3ItDGe1BoN1mCr1G4xL_vhMS8tcmcn3JhuihwsHvbzQv3309k3tBw8A",
The problem is I can make the class(es) that I need so I can deserialize the json because the json string has nested objects.
I used json2csharp to help me generate classes. After some merging and cleaning up, this is what I got:
public class InventoryItem
{
public string id { get; set; }
public string classid { get; set; }
public string instanceid { get; set; }
public string amount { get; set; }
public int pos { get; set; }
}
public class AppData
{
public string def_index { get; set; }
public int? is_itemset_name { get; set; }
public int? limited { get; set; }
}
public class Description
{
public string type { get; set; }
public string value { get; set; }
public string color { get; set; }
public AppData app_data { get; set; }
}
public class Action
{
public string name { get; set; }
public string link { get; set; }
}
public class Tag
{
public string internal_name { get; set; }
public string name { get; set; }
public string category { get; set; }
public string category_name { get; set; }
public string color { get; set; }
}
public class RgDescription
{
public string appid { get; set; }
public string classid { get; set; }
public string instanceid { get; set; }
public string icon_url { get; set; }
public string icon_url_large { get; set; }
public string icon_drag_url { get; set; }
public string name { get; set; }
public string market_hash_name { get; set; }
public string market_name { get; set; }
public string name_color { get; set; }
public string background_color { get; set; }
public string type { get; set; }
public int tradable { get; set; }
public int marketable { get; set; }
public int commodity { get; set; }
public string market_tradable_restriction { get; set; }
public List<Description> descriptions { get; set; }
public List<Action> actions { get; set; }
public List<Action> market_actions { get; set; }
public List<Tag> tags { get; set; }
}
public class RootObject
{
public bool success { get; set; }
public IDictionary<string, InventoryItem> rgInventory { get; set; }
public List<object> rgCurrency { get; set; }
public IDictionary<string, RgDescription> rgDescriptions { get; set; }
public bool more { get; set; }
public bool more_start { get; set; }
}
These appear to work correctly, you can deserialize and serialize with code like this:
var obj = JsonConvert.DeserializeObject<RootObject>(oldString);
Console.WriteLine(obj.rgDescriptions["310776560_302028390"].icon_url); // e.g.
var newString = JsonConvert.SerializeObject(obj,
new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
// null value handling is optional, the above makes it a little more like the source string
