I have API endpoint, that returning my JSON Object
Here is it
{
"results": [
{
"id": 182,
"title": "1-Day Private Beijing Tour to Tian'anmen Square, Forbidden City and Badaling Great Wall",
"price": "162",
"duration": "8",
"duration_type": "1",
"cover_image": {
"id": 308,
"img_path": "upload/images",
"img_file": "6d637884086151b30fe12db52fbaf5eb.jpg",
"status": "",
"created_at": "2018-02-27 02:25:36",
"updated_at": "2018-02-27 02:25:36",
"destination_id": "182",
"is_cover": "0",
"url": "https://api.xplorpal.com/upload/images/300x300/6d637884086151b30fe12db52fbaf5eb.jpg"
}
},
{
"id": 183,
"title": "One Day Private Beijing Tour to Mutianyu Great Wall and Summer Palace ",
"price": "197",
"duration": "8",
"duration_type": "1",
"cover_image": {
"id": 305,
"img_path": "upload/images",
"img_file": "1f8a09ddffb80ef9232f3511893ae5c4.jpg",
"status": "",
"created_at": "2018-02-27 02:22:19",
"updated_at": "2018-03-01 23:01:55",
"destination_id": "183",
"is_cover": "0",
"url": "https://api.xplorpal.com/upload/images/300x300/1f8a09ddffb80ef9232f3511893ae5c4.jpg"
}
}
]
}
I need to deserialize it
So I wrote this model
public class CoverImage
{
public int id { get; set; }
public string img_path { get; set; }
public string img_file { get; set; }
public string status { get; set; }
public string created_at { get; set; }
public string updated_at { get; set; }
public string destination_id { get; set; }
public string is_cover { get; set; }
public string url { get; set; }
}
public class Result
{
public int id { get; set; }
public string title { get; set; }
public string price { get; set; }
public string duration { get; set; }
public string duration_type { get; set; }
public CoverImage cover_image { get; set; }
}
public class RootObject
{
public List<Result> results { get; set; }
}
And trying to this like this
var responseExperiences = JsonConvert.DeserializeObject<IEnumerable<RootObject>>(content);
But when I run the project, I have this error:
Cannot deserialize the current JSON object (eg {"name":"value"}) into type 'System.Collections.Generic.IEnumerable`1[TravelApp.Models.GettingExperiences+Results]' 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) 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.
How I can fix this?
Your API returns an object with a single property named result
, not a collection. You should deserialize into a RootObject
object.
your JSON shows one object result
corresponding to RootObject
.
But you are trying to deserialize an array ( IEnumerable<>
) of RootObject
You should use this to deserialiaze the JSON showed :
JsonConvert.DeserializeObject<RootObject>(content);
您的api返回一个名为result的单个对象, 而不是一个需要简单地像单个对象一样反序列化的集合。
var responseExperiences = JsonConvert.DeserializeObject<RootObject>(content);
