将 JSON 递归反序列化为 IDictionary<string,obje

问题描述

我正在尝试将一些旧作品转换为使用 Newtonsoft JSON.NET.使用 System.Web.Script.Serialization.JavaScriptSerializer.Deserialize 方法的默认处理(例如，如果没有指定目标类型)是返回 Dictionary用于内部对象.

I'm trying to convert some older work to use Newtonsoft JSON.NET. The default handling using the System.Web.Script.Serialization.JavaScriptSerializer.Deserialize method (e.g. if no target type is specified) is to return a Dictionary<string,object> for inner objects.

这实际上是一个非常有用的 JSON 基本类型，因为它也恰好是 ExpandoObjects 使用的底层类型，并且是动态类型最明智的内部实现.

This is actually a really useful basic type for JSON since it also happens to be the underlying type used by ExpandoObjects and is the most sensible internal implementation for dynamic types.

如果我指定这种类型，例如:

If I specify this type, e.g.:

 var dict = JsonConvert.DeserializeObject<Dictionary<string,object>>(json);

JSON.NET 将正确反序列化最外层的对象结构，但它会为任何内部结构返回 JObject 类型.我真正需要的是将相同的外部结构用于任何内部对象类型结构.

JSON.NET will deserialize the outermost object structure correctly, but it returns a JObject type for any inner structures. What I really need is for the same outer structure to be used for any inner object-type structures.

有没有办法指定用于内部对象的类型，而不仅仅是返回的最外层类型?

Is there a way to specify a type to be used for inner objects, and not just the outermost type returned?

推荐答案

使用Json反序列化复杂对象时，需要添加一个JsonSerializer Settings作为参数.这将确保所有内部类型都能正确反序列化.

When Deserializing your complex objects using Json, you need to add a JsonSerializer Settings as a parameter. This will ensure that all of the inner types get deserialized properly.

    private JsonSerializerSettings _jsonSettings = new JsonSerializerSettings
    {
        TypeNameHandling = TypeNameHandling.All,
        TypeNameAssemblyFormat = FormatterAssemblyStyle.Full
    };

序列化对象时，可以使用 SerializerSettings:

When Serializing your object, you can use the SerializerSettings:

    string json= JsonConvert.SerializeObject(myObject, _jsonSettings)

然后在反序列化时，使用:

Then when you are deserializing, use:

    var dict = JsonConvert.DeserializeObject<Dictionary<string, object>>(json, _jsonSettings);

另外，当你序列化时，将 JsonSerializerSettings 添加到你的 SerializeObject(object, settings)

Also, when you serialize, add the JsonSerializerSettings to your SerializeObject(object, settings)

如果需要，您还可以更改 TypeNameHandling 和 TypeNameAssemblyFormat.我将它们分别设置为全部"和完整"，以确保我的复杂对象毫无疑问地正确序列化和反序列化，但智能感知为您提供其他选择

You can also change the TypeNameHandling and TypeNameAssemblyFormat if you need to. I have them set at 'All' and 'Full' respectively to ensure that my complex objects get serialized and deserialized properly without doubt, but intellisense provides you with other alternatives
