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)

using (var response = await httpClient.GetAsync(monstersUri + formatted))
{

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");

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/";
const string _songEndpoint = "songs/chart?time_period=day&chart_genre=all&per_page=10&page=1";
const string _host = "genius-song-lyrics1.p.rapidapi.com";
const string _key = "{key}";
public SongService(HttpClient httpClient)
{
_httpClient = httpClient;
}
public async Task<List<SongItem>> GetSong()
{
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'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}],"
Now, I need to create the object of type "Root" (My Model Class) for the purpose of picking and choosing certain values out of it. Shouldn't this line work for that?
Root MyObject = JsonConvert.DeserializeObject<Root>(result);
Here's the definition of Root.cs:

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 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; }

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
Found an odd issue when trying to deserialize a JSON string into a C# Object. It "seems" to perform the operation successfully (as in it does not throw any exception etc), however the outputted POCO contains does not contain any data from the JSON string, it only contains type default data (nulls,"", 0 etc). I have tried this process with other JSON and it works fine.

Any ideas - Im sure I have missed something glaringly obvious but I cannot see it. Using .NET 4.5
Help appreciated.

Look like you JSON string is not in correct format that you are trying to deserialize. For example i have not find show property in the C# class but it present in JSON.
So this issue I couldn't figure out in the night or early in the morning - it took me till this afternoon until I realised that I was had the wrong JSON!!, so no wonder it wasn't working! I got mixed up with a few different apis that provided JSON. Thanks to those who had pointed out that the class looks wrong, made me double check my code and realise the simplicity of this issue. Kinda needed some rubber ducking to spot the problem. Cheers
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.

private HttpClient client;

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.
