JsonIgnore属性在ASP.NET工作吗？ [英] JsonIgnore attributes not working in ASP.NET?

问题描述

我在我的循环引用了项目的对象。我已经把[JsonIgnore]场以上，像这样：

I've got an object in my project with circular references. I've put [JsonIgnore] above the field like so:

    [JsonIgnore]
    public virtual Foobar ChildObject { get; set; }

我仍然得到循环引用错误，当我序列化对象。不具有JsonIgnore唯一字段是字符串字段，不应导致此。有没有别的东西，我需要做的就是JsonIgnore工作？

I'm still getting circular reference errors when I serialize the object. The only fields that do not have JsonIgnore are string fields and should not cause this. Is there something else I need to do to get JsonIgnore to work?

谢谢！

推荐答案

您可能有一个链接回其父一些其他财产。使用 ReferenceLoopHandling.Ignore 设置为prevent自引用循环。

You likely have some other property that links back to its parent. Use the ReferenceLoopHandling.Ignore setting to prevent self-referencing loops.

using Newtonsoft.Json;

JsonSerializerSettings jsSettings = new JsonSerializerSettings();
jsSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;

string json = JsonConvert.SerializeObject(foobars, Formatting.None, jsSettings);
