我有这个类层次结构:
public class ProxyBotsSnapshotLogEntryDetails : IBotsSnapshotLogEntryDetails
{
public ICollection<IBotSnapshot> Snapshots { get; set; }
}
public class ProxyBotSnapshot : IBotSnapshot
{
public string Name { get; set; }
public ICollection<IBotSnapshotItem> States { get; set; }
}
public class ProxyBotSnapshotItem : IBotSnapshotItem
{
public int Count { get; set; }
public IrcBotChannelStateEnum State { get; set; }
}
及其相应的接口
public interface IBotsSnapshotLogEntryDetails
{
ICollection<IBotSnapshot> Snapshots { get; set; }
}
public interface IBotSnapshot
{
string Name { get; set; }
ICollection<IBotSnapshotItem> States { get; set; }
}
public interface IBotSnapshotItem
{
int Count { get; set; }
IrcBotChannelStateEnum State { get; set; }
}
我想从JSON反序列化:
var test = JsonConvert.DeserializeObject<ProxyBotsSnapshotLogEntryDetails>(entry.DetailsSerialized);
但我收到一条错误消息,说Newtonsoft无法转换接口。
我找到了这篇有前途的文章:
https://www.c-sharpcorner.com/UploadFile/20c06b/deserializing-interface-properties-with-json-net/
但我不确定如何使用该属性,因为在我的情况下,该属性是一个接口列表。

知道了!
文章中提供的转换器非常好用,我只是缺少在集合属性上使用它的语法。以下是包含转换器和工作属性的代码:
// From the article
public class ConcreteConverter<T> : JsonConverter
{
public override bool CanConvert(Type objectType) => true;
public override object ReadJson(JsonReader reader,
Type objectType, object existingValue, JsonSerializer serializer)
{
return serializer.Deserialize<T>(reader);
}
public override void WriteJson(JsonWriter writer,
object value, JsonSerializer serializer)
{
serializer.Serialize(writer, value);
}
}
public class ProxyBotsSnapshotLogEntryDetails : IBotsSnapshotLogEntryDetails
{
[JsonProperty(ItemConverterType = typeof(ConcreteConverter<ProxyBotSnapshot>))]
public ICollection<IBotSnapshot> Snapshots { get; set; }
}
public class ProxyBotSnapshot : IBotSnapshot
{
public string Name { get; set; }
[JsonProperty(ItemConverterType = typeof(ConcreteConverter<ProxyBotSnapshotItem>))]
public ICollection<IBotSnapshotItem> States { get; set; }
}
public class ProxyBotSnapshotItem : IBotSnapshotItem
{
public int Count { get; set; }
public IrcBotChannelStateEnum State { get; set; }
}
