Newtonsoft.Json 反序列化只设置默认值，数据不正确

Question

I am loading JSON data in my Unity project via Newtonsoft JsonConvert.Deserialize. This works in Editor and the json is valid. However, as soon as I make a Windows build, the serialized data is empty / filled with default values instead.

This is also shown when I serialize the deserialized data and output it:

• Json string read:

    {
        "galleries": [{
            "id": "Acker",
            "title": "Auf dem Acker",
            "slides": [],
            "path": "/ChangeableContentData/Auf dem Acker",
            "showAllInFolder": true,
            "foldersRecursive": false,
            "enableSlideshow": false,
            "slideshowSlideDuration": 5.0
        }],
        "cardMenus": [],
        "urls": []
    }

• reserialized:

    {
        "galleries": [{
            "id": null,
            "title": "",
            "slides": null,
            "path": "",
            "showAllInFolder": true,
            "foldersRecursive": true,
            "enableSlideshow": false,
            "slideshowSlideDuration": 5.0
        }],
        "cardMenus": []
    }

Here is the relevant C# class:

    [System.Serializable]
    [Preserve]
    public partial class UIContentData
    {
        [JsonProperty("galleries")]
        public List<UIContentGalleryData> galleries { get; set; }
        [JsonProperty("cardMenus")]
        public List<UIContentCardMenuData> cardMenus { get; set; }
        [JsonProperty("urls")]
        public List<UIContentUrlData> urls { get; set; }
    
        public UIContentData() { }
    }

    [System.Serializable]
    [Preserve]
    public partial class UIContentGalleryData
    {
        public string id { get; set; }
        [JsonProperty("title")]
        public string title { get; set; } = ""; // optional
        [JsonProperty("slides")]
        public List<UIContentGallerySlide> slides { get; set; }
        [JsonProperty("path")]
        public string baseFolderPath { get; set; } = "";
        [JsonProperty("showAllInFolder")]
        public bool showAllInFolder { get; set; } = true; // optional
        [JsonProperty("foldersRecursive")]
        public bool foldersRecursive { get; set; } = true; // optional
        [JsonProperty("enableSlideshow")]
        public bool enableSlideshow { get; set; } = false; // optional
        [JsonProperty("slideshowSlideDuration")]
        public float slideshowSlideDuration { get; set; } = 5f; // optional
    
        public UIContentGalleryData() { }
    }

Edit for clarity: I am using UIContentData object to deserialize.

JsonConvert.DeserializeObject<UIContentData>(json);

Any help is much appreciated!

Answer 1

You are using the wrong class,should create one more. This code was tested and working properly

var data=JsonConvert.DeserializeObject<Root>(json);

public class Root
    {
        public List<UIContentGalleryData> galleries { get; set; }
        public List<object> cardMenus { get; set; }
        public List<object> urls { get; set; }
    }

and remove slides property from UIContentGallerySlide

[JsonProperty("slides")]
    public List<UIContentGallerySlide> slides { get; set; }

Found the issue. Unity was stripping the class definitions I believe. Adding a link.xml with preserve="all" for the assembly containing them solved the problem!
