Json.NET：反序列化嵌套字典

将对象反序列化为Dictionary （ JsonConvert.DeserializeObject<IDictionary>(json) ）时，嵌套对象被反序列JObject s。 是否可以强制嵌套对象反序列化为Dictionary ？

Answer 1

我找到了一种方法Dictionary通过提供CustomCreationConverter实现将所有嵌套对象转换为Dictionary ：

 class MyConverter : CustomCreationConverter> { public override IDictionary Create(Type objectType) { return new Dictionary(); } public override bool CanConvert(Type objectType) { // in addition to handling IDictionary // we want to handle the deserialization of dict value // which is of type object return objectType == typeof(object) || base.CanConvert(objectType); } public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) { if (reader.TokenType == JsonToken.StartObject || reader.TokenType == JsonToken.Null) return base.ReadJson(reader, objectType, existingValue, serializer); // if the next token is not an object // then fall back on standard deserializer (strings, numbers etc.) return serializer.Deserialize(reader); } } class Program { static void Main(string[] args) { var json = File.ReadAllText(@"c:\test.json"); var obj = JsonConvert.DeserializeObject>( json, new JsonConverter[] {new MyConverter()}); } } 

文档： 带有Json.NET的CustomCreationConverter

替代/更新：

我需要反序列化String的词典字典，并使用当前的Json.NET（5.0）我不必创建CustomConverter，我刚刚使用（在VB.Net中）：

 JsonConvert.DeserializeObject(Of IDictionary(Of String, IDictionary(Of String, String)))(jsonString) 

或者，在C＃中：

 JsonConvert.DeserializeObject>(jsonString);
