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 ;
}
private void Configure()
{
_httpClient.BaseAddress = new Uri(_baseUrl);
_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'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");

I have the following class
public class CallbackResultsJson
{
public class CallbackResults
{
public string Status { get; set; }
public string Message { get; set; }
public string Data { get; set; }
public string Log { get; set; }
public string StatusText { get; set; }
public string TransactionToken { get; set; }
}
}
I am trying to use Json.Net to Deserialize requestbody but I am always getting a null for status,data. any ideas why ?
var requestbody =#"
{
"CallbackResults":
{
"TransactionToken":"b65524-qwe",
"Status":0,
"Message":"Publish Application to QaLevel Operation Completed",
"Data":[],
"Log":["sucess"
},
"RequestNumber":"REQ1234"
}"
var TransactionResult = JsonConvert.DeserializeObject<CallbackResultsJson.CallbackResults>(requestBody);
Just a little bit of change should be done.
Your class:
public class CallbackResultsJson
{
public CallbackResultsClass CallbackResults { get; set; }
public string RequestNumber { get; set; }
public class CallbackResultsClass
{
public int Status { get; set; }
public string Message { get; set; }
public string[] Data { get; set; }
public string Log { get; set; }
public string TransactionToken { get; set; }
}
}
Your data:
var requestbody = #"
{
""CallbackResults"":
{
""TransactionToken"":""b65524-qwe"",
""Status"":0,
""Message"":""Publish Application to QaLevel Operation Completed"",
""Data"":[""Data1"", ""Data2""],
""Log"":""sucess""
},
""RequestNumber"":""REQ1234""
}";
var result = JsonConvert.DeserializeObject<CallbackResultsJson>(requestbody);
Your class needs to have a property of the sub-type,
public class CallbackResultsJson
{
public CallBackResults CallbackResults { get; set; }
public string RequestNumber { get; set; )
public class CallbackResults
{
public string Status { get; set; }
public string Message { get; set; }
public string Data { get; set; }
public string Log { get; set; }
public string StatusText { get; set; }
public string TransactionToken { get; set; }
}
}
var result = JsonConvert.DeserializeObject<CallbackResultsJson>(requestBody);
I have used json2csharp.com to convert requestbody to c# classes and it generated these classes.it worked
public class CallbackResults
{
public string TransactionToken { get; set; }
public int Status { get; set; }
public string Message { get; set; }
public List<string> Data { get; set; }
public List<string> Log { get; set; }
}
public class CallbackResultsRootObj
{
public CallbackResults VdiCallbackResults { get; set; }
public string RequestNumber { get; set; }
}
var vdiTransactionResult = JsonConvert.DeserializeObject<CallbackResultsRootObj>(requestBody);

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);
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()

var response = await client.GetAsync(new Uri("http://api.yousee.tv/rest/tvguide/nowandnext/"));

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.
