I'm using https://www.timeanddate.com/ this API for holiday details.

When I debugge The HttpClient response messege is "The operation was canceled." '($exception).CancellationToken.WaitHandle' threw an exception of type 'System.ObjectDisposedException'

and response in POSTMAN is [ ] (response type : 200k).

controller

 public async Task<IActionResult> Get(string country, int year)
        {
            List<Holidays> holidays = new List<Holidays>();
            holidays = await _holidayService.GetHolidays(country, year);

            return Ok(holidays);
        }

service

   public HolidayService(HttpClient client)
        {
            _client = client;
            _client.Timeout = TimeSpan.FromMinutes(3);
        }

        public async Task<List<Holidays>> GetHolidays(string country, int year)
        {
            string url = string.Format($"/holidays?accesskey=ACCESSKEY&secretkey=SECRET&version=3&country=ro&year=2021&lang=en");
            var result = new List<Holidays>();

            try
            {
                using var response = await _client.GetAsync(url);
            }
            // Filter by InnerException.
            catch (TaskCanceledException ex) when (ex.InnerException is TimeoutException)
            {
                // Handle timeout.
                Console.WriteLine("Timed out: " + ex.Message);
            }
            catch (TaskCanceledException ex)
            {
                // Handle cancellation.
                Console.WriteLine("Canceled: " + ex.Message);
            }

            return result;


        }

startup

  HttpClientsConfig.InjectServices(services, Configuration);
            services.AddHttpClient<IHolidayService, HolidayService>(c =>
            {
                c.BaseAddress = new System.Uri(Configuration.GetValue<string>("Holiday:Url"));
                c.DefaultRequestHeaders.Add("Accept", "application/json");
            });

AppSetting.development.json

"Holiday": {
  "AccessKey": "MY_ACCESS_KEY",
  "SecretKey": "MY_SECRET_KEY",
  "Url": "https://api.xmltime.com"
}

HOW CAN I GET ALL RESPONSE WHICH IS LIKE THIS https://api.xmltime.com/holidays?accesskey={MY_ACCESS_KEY}&secretkey={MY_SECRET_KEY}&version=3&country=ro&year=2021&lang=en

You could try to deserialize the response like below

  public async Task<List<Holidays>> GetHolidays(string country, int year)
    {
        string url = string.Format($"/holidays?accesskey=ACCESSKEY&secretkey=ACCESSKEY&version=3&country=ro&year=2021&lang=en");
        var result = new List<Holidays>();

        try
        {
           _client.Timeout= Timespan. FromMinutes(30);
            using var response = await _client.GetAsync(url);
            string jsonString= await response.Content.ReadAsStringAsync();
            var root=JsonConvert.DeserializeObject<Root>(jsonString);
            return root.holidays;
        }
        // Filter by InnerException.
        catch (TaskCanceledException ex) when (ex.InnerException is TimeoutException)
        {
            // Handle timeout.
            Console.WriteLine("Timed out: " + ex.Message);
        }
        catch (TaskCanceledException ex)
        {
            // Handle cancellation.
            Console.WriteLine("Canceled: " + ex.Message);
        }
        return result;
    }

Alternatively you can use the nuget package

dotnet add package TimeAndDate.Services

var country = "no";
var service = new HolidaysService('accessKey', 'secretKey');
var result = service.GetHolidaysForCountry(country, 2020);
