i having issues getting the elements in data into a list.
I want to be able to get User_ID
, Country
, Continent
and other elements to a list after which i will do a bulk insert to the database.
The Error i get Error Message An exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in mscorlib.dll but was not handled in user code
Additional information: Cannot deserialize the current JSON object (eg {"name":"value"}) into type 'System.Collections.Generic.List`1[Country_API.Response]' because the type requires a JSON array (eg [1,2,3]) to deserialize correctly.
To fix this error either change the JSON
to a JSON
array (eg [1,2,3]) or change the deserialized type so that it is a normal .NET
type (eg not a primitive type like integer, not a collection type like an array or List<T>
) 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.
This is the JSon Data returned from the API
{
"Status": "200 Ok",
"Message": "Data retrieved",
"Response": {
"current_page": 1,
"data": [
{
"User-ID": "EAD001",
"Country": "Ghana",
"Continent": "Africa",
"Gender": "Male",
"Email": "ead1@yahoo.com",
"Religion": ""
},
{
"User-ID": "EAD002",
"Country": "Senegal",
"Continent": "Africa",
"Gender": "Female",
"Email": "ead2@yahoo.com",
"Religion": "Muslim"
}
]
}
}
I am trying to Deserilize but it throws the above error.. this is what i am trying
if (result.IsSuccessStatusCode)
{
string toJsonString = await result.Content.ReadAsStringAsync();
var deserialize = JsonConvert.DeserializeObject<List<Response>>(toJsonString);
}
Json Model
public class Data
{
public string User-ID { get; set; }
public string Country { get; set; }
public string Continent { get; set; }
public string Gender { get; set; }
public string Email { get; set; }
public string Religion { get; set; }
}
public class Response
{
public int current_page { get; set; }
public IList<Data> data { get; set; }
}
public class Application
{
public string Status { get; set; }
public string Message { get; set; }
public Response Response { get; set; }
}
How to i achieve this please?
You're trying to deserialize the List inside the object. You need to deserialize the entire object. Try this:
if (result.IsSuccessStatusCode)
{
string toJsonString = await result.Content.ReadAsStringAsync();
var deserialize = JsonConvert.DeserializeObject<Application>(toJsonString);
IList<Data> dataList = deserialize.Response.data;
}
Issue is here. You have used "List" instead of "Response". bcoz in JSON "Response" is object not a list
var deserialize = JsonConvert.DeserializeObject<List<Response>>(toJsonString);
use like this.
var deserialize = JsonConvert.DeserializeObject<Response>(toJsonString);
