C# Json 序列化支持字段引用属性而不是相反

Question

我使用 NewtonSoft.Json 最新版本，需要 serdes 第三方对象。我需要序列化字段。这是我使用的 JsonSerializerSettings：

JsonSerializerSettings settings_ = new JsonSerializerSettings
{
    NullValueHandling = NullValueHandling.Include,
    DefaultValueHandling = DefaultValueHandling.Include,
    PreserveReferencesHandling = PreserveReferencesHandling.All,
    ObjectCreationHandling = ObjectCreationHandling.Replace,
    ReferenceLoopHandling = ReferenceLoopHandling.Serialize,
    ContractResolver = new DynamicContractResolver(),
};
public class DynamicContractResolver : DefaultContractResolver
{
    protected override IList<JsonProperty> CreateProperties(Type type, Newtonsoft.Json.MemberSerialization memberSerialization)
    {
        IList<JsonProperty> properties = base.CreateProperties(type, memberSerialization);
        properties = properties.Where(p => p.PropertyName != "MonitoringInstance" && p.PropertyName != "SessionInstance").ToList();
        var fields = type.GetFields(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance).Select(f => CreateProperty(f, memberSerialization));
        return properties.Union(fields, new EqualityComparer()).ToList();
    }
}

不幸的是，无论我如何尝试，支持字段都引用了属性。有没有办法扭转它？任何见解都值得赞赏。

用DataContractAttribute 简单地装饰你的类，用DataMemberAttribute 装饰字段要容易得多。除非你真的想自己实现合约解析器，否则这就是我们一直在用 JSON 做的事情。
