反序列化与已知和未知领域JSON [英] Deserialize json with known and unknown fields

问题描述

由于以下JSON结果：
默认的JSON结果是一组已知的领域：

Given following json result: The default json result has a known set of fields:

{
    "id": "7908",
    "name": "product name"
}

但可以用其他字段进行扩展（在这个例子中 _unknown_field_name_1 和 _unknown_field_name_2 ），它的名字都没有请求的结果时称。

But can be extended with additional fields (in this example _unknown_field_name_1 and _unknown_field_name_2) of which the names are not known when requesting the result.

{
    "id": "7908",
    "name": "product name",
    "_unknown_field_name_1": "some value",
    "_unknown_field_name_2": "some value"
}

我想JSON结果被序列化和反序列化，并从一类为已知油田属性和映射未知的字段（其中有没有属性）一个属性（或多个属性）像一本字典等等他们可以访问和修改。

I would like the json result to be serialized and deserialized to and from a class with properties for the known fields and map the unknown fields (for which there are no properties) to a property (or multiple properties) like a dictionary so they can be accessed and modified.

public class Product
{
    public string id { get; set; }
    public string name { get; set; }
    public Dictionary<string, string> fields { get; set; }
}

我想我需要一种方法来插入JSON序列化和失踪人员本人（无论是序列化和反序列化）进行映射。
我一直在寻找各种可能性：

I think I need a way to plug into a json serializer and do the mapping for the missing members myself (both for serialize and deserialize). I have been looking at various possibilities:

• json.net和定制合同解析器（无法弄清楚如何做到这一点）


• datacontract串行器（只能覆盖onserialized，onserializing）


• 序列化到动态并进行自定义映射（这可能工作，但似乎很多工作）


• 让产品从DynamicObject（串行器与反思工作，不调用trygetmember和trysetmember方法）
继承

我使用restsharp，但任何串行器可以插入。

I'm using restsharp, but any serializer can be plugged in.

哦，我不能改变JSON结果和这或<一个href=\"http://stackoverflow.com/questions/13072447/how-to-deserialize-variable-size-json-string-with-variable-names\">this没有帮助我满意。

Oh, and I cannot change the json result, and this or this didn't help me either.

什么你要找的是一个自定义的 JsonConverter

What you were looking for was a custom JsonConverter
