如何使用 Newtonsoft.Json 正确反序列化数组中的嵌套对象？

Question

I'm facing this json data:

{
    "pagemeta": {
        "slug": "/",
        "title": "test",
        "description": "test"
    },
    "navigationlinks": {
        "links": [{
            "navigationlink": {
                "name": "Index.",
                "url": "/"
            }
        }]
    }
}

And both using HttpRespondeMessage.Content.ReadAsJsonAsync<T>(); or JsonConvert.DeserializeAnonymousType(jsonString, new MyClassToDeserializeInto()) Both parsings seem to function well, except when it comes to the objects inside the array "links" .

Those do get to become object in the array in class but all data is null (both name and url like in this example).

Am I doing something wrong to don't get the json deserialized correctly?

Following are the classes that I use as the final target object:

HomeData.cs

public sealed class HomeData
    {
        [JsonProperty("pagemeta")]
        public PageMeta PageMeta { get; set; }
        [JsonProperty("navigationlinks")]
        public NavigationLinks NavigationLinks { get; set; }
    }

NavigationLinks.cs

public class NavigationLinks
    {
        [JsonProperty("links")]
        public NavigationLink[] Links { get; set; }
    }

NavigationLink.cs

public class NavigationLink
    {
        [JsonProperty("name")]
        public string Name { get; set; }
        [JsonProperty("url")]
        public string Url { get; set; }
    }

meanwhile the PageMeta.cs does the data correctly.

Answer 1

You have missed the Links class, and mark the Links class as JsonObject

public sealed class HomeData
{
    [JsonProperty("pagemeta")]
    public PageMeta PageMeta { get; set; }
    [JsonProperty("navigationlinks")]
    public NavigationLinks NavigationLinks { get; set; }
}

public class PageMeta
{
    [JsonProperty("slug")]
    public string Slug { get; set; }

    [JsonProperty("title")]
    public string Title { get; set; }

    [JsonProperty("description")]
    public string Description { get; set; }
}

public class NavigationLink
{
    [JsonProperty("name")]
    public string Name { get; set; }
    [JsonProperty("url")]
    public string Url { get; set; }
}

public class NavigationLinks
{
    [JsonProperty("links")]
    public Links[] Links { get; set; }
}

[JsonObject]
public class Links
{
    [JsonProperty("navigationlink")]
    public NavigationLink NavigationLink { get; set; }
}

And then use it like this :

var homedata = JsonConvert.DeserializeAnonymousType(text, new HomeData());
