反序列化属性作为使用JSON.NET的ExpandoObject [英] Deserialize a property as an ExpandoObject using JSON.NET

问题描述

例如，有像下一个对象：

For example, there's an object like the next one:

public class Container
{
   public object Data { get; set; }
}

和它的使用是这样的：

Container container = new Container
{
    Data = new Dictionary<string, object> { { "Text", "Hello world" } }
};

如果我反序列化从序列上面的实例中，获得的数据JSON字符串属性，即使我提供 ExpandoObjectConverter ，这不是反序列化作为一个 ExpandoObject ：

If I deserialize a JSON string obtained from serializing the above instance, the Data property, even if I provide the ExpandoObjectConverter, it's not deserialized as an ExpandoObject:

Container container = JsonConvert.Deserialize<Container>(jsonText, new ExpandoObjectConverter());

如何反序列化与匿名对象指定一个类属性，或者至少不具体类型为 ExpandoObject

How can I deserialize a class property assigned with an anonymous object, or at least, not concrete type as an ExpandoObject?

的有人回答，我可以只使用动态对象。这不会为我工作。我知道我可以走这条路，而是因为我需要一个ExpandoObject不是这种情况。
谢谢的

的其他一些用户回答我可以反序列化一个JSON字符串转换成 ExpandoObject 。这不是这个问题的目的。我需要反序列化具有动态性的具体类型。在JSON字符串该属性可能是一个关联数组的

Some other user answered I could deserialize a JSON string into an ExpandoObject. This isn't the goal of this question. I need to deserialize a concrete type having a dynamic property. In the JSON string this property could be an associative array.

推荐答案

试试这个：

Container container = new Container
{
    Data = new Dictionary<string, object> { { "Text", "Hello world" } }
};

string jsonText = JsonConvert.SerializeObject(container);

var obj = JsonConvert.DeserializeObject<ExpandoObject>(jsonText, new ExpandoObjectConverter());

我发现，这样做让我的 ExpandoObject 从调用 DeserializeObject 。我想与您所提供的代码的问题是，当你在提供一个 ExpandoObjectConverter ，你问 Json.Net 反序列化集装箱，所以我会想象， ExpandoObjectConverter 不被使用。

I found that doing this got me an ExpandoObject from the call to DeserializeObject. I think the issue with the code you have provided is that while you are supplying an ExpandoObjectConverter, you are asking Json.Net to deserialize a Container, so I would imagine that the ExpandoObjectConverter is not being used.

编辑：

如果我装点数据财产 [JsonConverter（typeof运算（ExpandoObjectConverter））] ，并使用代码：

If I decorate the Data property with [JsonConverter(typeof(ExpandoObjectConverter))] and use the code:

var obj = JsonConvert.DeserializeObject<Container>(jsonText);

然后数据属性被反序列化到 ExpandoObject ，而 OBJ 是集装箱。

Then the Data property is deserialized to an ExpandoObject, while obj is a Container.
