JSON映射的无效类属性声明

Question

I have below json received from mailgun API .

{
  "items": [{
    "delivery-status": {
      "message": null,
      "code": 605,
      "description": "Not delivering to previously bounced address",
      "session-seconds": 0
    },
    "event": "failed",
    "log-level": "error",
    "recipient": "test@test.com"
  },
  {
      //some other properties of above types
  }]
}

Now I was trying to create a class structure for above json to auto-map the properties after deserializing .

public class test
{
    public List<Item> items { get; set; }
}
public class Item
{
    public string recipient { get; set; }
    public string @event { get; set; }
    public DeliveryStatus delivery_status { get; set; }
}

public class DeliveryStatus
{
    public string description { get; set; }
}

This is how I deserialize and try to map the properties.

var resp = client.Execute(request);
var json = new JavaScriptSerializer();
var content = json.Deserialize<Dictionary<string, object>>(resp.Content);
test testContent = (test)json.Deserialize(resp.Content, typeof(test));
var eventType = testContent.items[0].@event;
var desc = testContent.items[0].delivery_status.description; //stays null

Now in the above class Item , recipient and @event gets mapped properly and since it was a keyword I was suppose to use preceding @ character and it works well. But the delivery-status property from json , does not get mapped with delevery_status property in class DeliveryStatus . I have tried creating it as deliveryStatus or @deliver-status . The earlier on doesn't map again and the later one throws compile time exception. Is there anyway these things can be handled, like declaring a property with - in between? I cannot change response json as it is not getting generated from my end. Hoping for some help.

Update

Changed the class as below referring this answer , but did not help. Its null again.

public class Item
{
    public string @event { get; set; }

    [JsonProperty(PropertyName = "delivery-status")]
    public DeliveryStatus deliveryStatus { get; set; }
}

I am not sure what the issue is at your end, but at least it works if you use this code. Make sure to include a recent version of Newtonsoft.Json in your project and you should be fine.

public class DeliveryStatus
{
    public object message { get; set; }
    public int code { get; set; }
    public string description { get; set; }
    [JsonProperty("session-seconds")]
    public int session_seconds { get; set; }
}

public class Item
{
    [JsonProperty("delivery-status")]
    public DeliveryStatus delivery_status { get; set; }
    public string @event { get; set; }
    [JsonProperty("log-level")]
    public string log_level { get; set; }
    public string recipient { get; set; }
}

public class RootObject
{
    public List<Item> items { get; set; }
}

public static void Main(string[] args)
{
        string json = @"{
  ""items"": [{
    ""delivery-status"": {
                ""message"": null,
      ""code"": 605,
      ""description"": ""Not delivering to previously bounced address"",
      ""session-seconds"": 0
    },
    ""event"": ""failed"",
    ""log-level"": ""error"",
    ""recipient"": ""test@test.com""
  }]
}";

    RootObject r = JsonConvert.DeserializeObject<RootObject>(json);
}
