在C#中解析JSON [英] Parsing JSON in C#

问题描述

我从RESTful API以JSON对象的形式返回响应.通常，当密钥已知时，我可以很好地解析它.例如，我创建一个User类，如下所示:

I am getting a response back from a RESTful API in the form of a JSON object. Normally, I can parse this just fine when the keys are known. For instance, I create a User class like this:

[DataContract]
public class User
{
    [DataMember]
    public string id { get; set; }

    [DataMember]
    public string name { get; set; }

    [DataMember]
    public string email { get; set; }
}

我所要做的就是将响应读取到我的JSON解串器中，并告诉其输出是< User>我很好.在发出其他请求(例如销售数据)时，这不足.我得到的回复是这样的:

All I have to do is pull read the response into my JSON deserializer and tell it the output is a <User> and I'm good to go. This falls short when making other requests, such as sales data. The response I get back is something like this:

{
  "2010-11-24": {
    "country": null,
    "iso": null,
    "product": null,
    "downloads": 39,
    "net_downloads": 38,
    "updates": 6,
    "revenue": "19.02",
    "returns": 1,
    "gift_redemptions": 0,
    "promos": 0
  },
  "2010-11-25": {
    "country": null,
    "iso": null,
    "product": null,
    "downloads": 63,
    "net_downloads": 63,
    "updates": 6,
    "revenue": "37.00",
    "returns": 0,
    "gift_redemptions": 0,
    "promos": 0
  }
}

如果我可以将此类建模为[DataContract]，那我会很高兴，但是由于第一个键是日期，因此我无法对此进行硬编码.

If I could model this class as a [DataContract] then I'd be golden, but since the first key is a date, I can't hard code that.

是否存在一个可以接受这种响应并将其转换为强类型C#类的JSON库?

Is there a JSON library out there that can take this kind of response and turn it into a strongly-typed C# class?

为了记录，我使用的是此SO问题中使用的JSONHelper.

For the record, I'm using the JSONHelper used in this SO question.

推荐答案

JSON.NET 被认为是最好/最快/最稳定的JSON C#库.我已经用过了，它可以像宣传的那样工作.

JSON.NET is recognized as the best/fastest/most stable JSON C# library. I've used it, it works as advertised.
