Deserializing an array of objects

Question

I am having difficult de-serializing the following JSON

[{"JobID": 397597,"CustomerId": "ENV"},
 {"JobID": 397694,"CustomerId": "UNI015"},
 {"JobID": 397836,"CustomerId": "AMA003"}]

JobData Class
   public class JobData
    {
        [JsonProperty("JobID")]
        public int JobID;
        [JsonProperty("CustomerId")]
        public string CustomerId;
    }
   

This is the REST Service class

    public class RESTService
    {
        readonly HttpClient _client;

        public RESTService()
        {
            _client = new HttpClient();
        }

        public async Task<List<JobData>> GetJobData(string query)
        {
            List<JobData> jobData = null;
            try
            {
                var response = await _client.GetAsync(query);
                if (response.IsSuccessStatusCode)
                {
                    var content = await response.Content.ReadAsStringAsync();
                    jobData = JsonConvert.DeserializeObject<List<JobData>>(content);
                }
            }
            catch (Exception ex)
            {
                Debug.WriteLine("\t\tERROR {0}", ex.Message);
            }

            return jobData;
        }
    }
}

I wish to read the JSON response into a Xamarin Listview but no data is returned. The content variable returns a valid JSON string.

Answer 1

Try to configure it in the Startup.cs class with services.AddNewtonsoftJson();

As second I would initialize JobData. var jobData = new List<JobData>(); This is better than using null.

If this doesn't work, debug the program and look what var content contains. If you know what content contains, it can bring you a lot further.
