我目前正在处理的项目有一个非常相似的问题:我想制作一个自定义JsonConverter并通过属性将其映射到我的实体，但随后代码陷入了无限循环.

I had a very similar problem with a project that I am currently working on: I wanted to make a custom JsonConverter and map it to my entities via attributes, but then the code got trapped in an infinite loop.

在我的情况下，技巧是使用serializer.Populate而不是JObject.ToObject(即使我愿意也不能使用.ToObject；我使用的是3.5.8版，其中该功能不存在).下面是我的ReadJson方法作为示例:

What did the trick in my case was using serializer.Populate instead of JObject.ToObject (I couldn't use .ToObject even if I wanted to; I am using version 3.5.8, in which this function does not exist). Below is my ReadJson method as an example:

public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
    JContainer lJContainer = default(JContainer);

    if (reader.TokenType == JsonToken.StartObject)
    {
        lJContainer = JObject.Load(reader);
        existingValue = Convert.ChangeType(existingValue, objectType);
        existingValue = Activator.CreateInstance(objectType);

        serializer.Populate(lJContainer.CreateReader(), existingValue);
    }

    return existingValue;
}
