在Json对数组C＃的响应中反序列化对象

Question

Currently I'm writing a mobile app with Xamarin.Forms and my problem is, that I need the response from my API in separate variables instead of one string output.

My API output:

{"error":false,"user":{"id":3,"email":"root@root.de","vorname":"root","nachname":"toor","wka":"wka1"}}

I'm using Newtonsoft to deserialize the response and I think that the problem is the curly bracket behind "user":{...} because I can print out public bool error { get; set; } public bool error { get; set; } public bool error { get; set; } but the other vars are not working.

class JsonContent
    {
        public bool error { get; set; }
        public int id { get; set; }
        public string email { get; set; }
        public string vorname { get; set; }
        public string nachname { get; set; }
        public string wka { get; set; }
    }

Tests:

JsonContent j = JsonConvert.DeserializeObject<JsonContent>(response.Content);
bool pout = j.error;  //output: false

JsonContent j = JsonConvert.DeserializeObject<JsonContent>(response.Content);
int pout = j.id;  //output: 0

Answer 1

The C# class that you have for your JSON is not correct.

It should be

public class User
{
    public int id { get; set; }
    public string email { get; set; }
    public string vorname { get; set; }
    public string nachname { get; set; }
    public string wka { get; set; }
}

public class JsonContent
{
    public bool error { get; set; }
    public User user { get; set; }
}

and then you can deserialize your JSON to your C# objects

Answer 2

You can use some json to c# converter to get the model, ie https://jsonutils.com , http://json2csharp.com . It will help you when you have to get the model of a big json.

public class User
{
   public int id { get; set; }
   public string email { get; set; }
   public string vorname { get; set; }
   public string nachname { get; set; }
   public string wka { get; set; }
}

public class Example
{
    public bool error { get; set; }
    public User user { get; set; }
}
