反序列化json的C＃最佳对象或类结构

Question

I have a json structured like that:

{
  "eventType1": {
    "unitName": "nameValue",
    "comment": "initial comment"
  },
  "eventType2": {
    "comment": "initial message"
  },
}

When I deserialize it the appropriate type seems to be something like Dictionary<string, <Dictionary<string,string>>> and method would look like that:

public static Dictionary<string, Dictionary<string, string>> defaultFieldDataByEvent =
        JsonConvert
        .DeserializeObject<Dictionary<string, Dictionary<string, string>>>(defaultFieldDataByEventSerialized);

which looks, well, ugly. But that's exactly how I need it to extract the data - defaultFieldDataByEvent[eventType][field] .

Can I encapsulate the type into something somehow or is there a different approach to such cases?

I see multiple possible options here. Hope any of these helps.

• You may try to add a type alias with using directive to make code shorter, but this won't be convenient, if logic is spread across multiple files, because you will be forced to duplicate this alias.
• You may try to use JObject.Parse for deserialization, staying on lower level. But as far as your json structure is pretty various, this approach may work well.
• You may try to deserialize your data into ExpandoObject . It's rather similar to JObject , except you will get pretty nice dynamic code (dynamic is not a problem here since compiler won't help you with Dictionary either), but it, obviously will be less performant. You could lose your custom types information, since everything in your graph will become an ExpandoObject , but seems like that's not an issue for your case. Example may be found here.
• You may try to use [JsonExtensionData] as @dbc suggested. See How to serialize a Dictionary as part of its parent object using Json.Net .
