在.NET中反序列化JSON响应时处理空字典

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;

public class EmptyDictionaryConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return objectType.IsGenericType && objectType.GetGenericTypeDefinition() == typeof(Dictionary<,>);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        if (reader.TokenType == JsonToken.Null)
            return null;

        var jsonObject = JObject.Load(reader);

        if (jsonObject.Count == 0)
            return Activator.CreateInstance(objectType);

        return jsonObject.ToObject(objectType);
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }
}

string jsonResponse = "{ \"data\": {} }"; // JSON响应

var settings = new JsonSerializerSettings();
settings.Converters.Add(new EmptyDictionaryConverter());

var response = JsonConvert.DeserializeObject<Response>(jsonResponse, settings);
