here is my Json Object
{
"id":5,
"url":"http://localhost:8001/api/courses/5",
"name":"Professional Experience II",
"duration":"5.0",
"description":"The course will talk in depth about every thing",
"tutor": {
"id":2,
"email":"[email protected]",
"userName":"TA",
"firstName":"T",
"lastName":"A",
"gender":0
},
"subject":
{
"id":2,
"name":"Science"
}
}
and my model for is here
public class CourseModel
{
public int Id { get; set; }
public string Url { get; set; }
public string Name { get; set; }
public double Duration { get; set; }
public string Description { get; set; }
public TutorModel Tutor { get; set; }
public SubjectModel Subject { get; set; }
}
and this is how i am getting this object. I am able to get the jsonObject but not able to Deserialize it to its corresponding model
string url = "http://localhost:8001/api/courses/5";
HttpResponseMessage responseMessage = await client.GetAsync(url);
if (responseMessage.IsSuccessStatusCode)
{
var responseData = responseMessage.Content.ReadAsStringAsync().Result;
var data = JsonConvert.DeserializeObject<List<CourseModel>>(responseData);
return View(data);
}
return View("Error:);
Error i am getting is
Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[Learning.Web.Models.CourseModel]' 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 'id', line 1, position 6.
I am using WebApi and I am not sure what i am doing wrong here .. Any help will be appreciated
Updated:
Based on Shyju and Habib answer it does work if i deserialize it to a single instance but if i change the url to
string url = "http://localhost:8001/api/courses";
and deserialize it to List, i get same error, here is the json object
