c# - 将json的动态属性读入.net C#

Question

我在访问 API 后得到以下 json 格式:

{
    "7407": {
        "survey_id": "406",
        "device_id": "1",
        "response_time": "2013-10-10 16:14:01",
        "timezone": "0",
        "language_id": "en",
        "response_id": "7407",
        "device_alias": "QR Code App",
        "site_name": "QR Code App",
        "country_name": "United States",
        "state_name": "New York",
        "city_name": "Suffern",
        "zip": "",
        "voucher_name": null,
        "voucher_mode": null,
        "surveyee_name": null,
        "surveyee_email": null,
        "surveyee_phone": null,
        "ques": {
            "": []
        }
    },
    "7408": {
        "survey_id": "406",
        "device_id": "1",
        "response_time": "2013-10-10 16:36:56",
        "timezone": "0",
        "language_id": "en",
        "response_id": "7408",
        "device_alias": "QR Code App",
        "site_name": "QR Code App",
        "country_name": "India",
        "state_name": "Gujarat",
        "city_name": "Ahmedabad",
        "zip": "",
        "voucher_name": null,
        "voucher_mode": null,
        "surveyee_name": null,
        "surveyee_email": null,
        "surveyee_phone": null,
        "ques": {
            "": []
        }
    } }

我正在使用 JSON.Net 读取上面给定的 json 数据。

要将此数据映射到 .Net 代码，我需要 .net 中的类，其属性名称与 json 字符串中的名称相同。但是 json 中有一些属性可以是动态的(在我的例子中是“7407”、“7408”等)，即这个值可以根据我们传递给参数的内容进行更改。

我的问题是，我们如何将 json 属性(本质上是动态的，并且可以根据提供给 api 的参数具有任何值)映射到我们的 .net 类？

Answer 1

您可以将其映射到字典。您的动态属性是 DictionaryIem 的键，Objet 是您的 DictionaryItem 的值。

例如:

public class MyClass
{
    public void readJson)
    {
        var json = "{\"7407\": {\"survey_id\": \"406\",\"device_id\": \"1\",},\"7408\": {\"survey_id\": \"406\",\"device_id\": \"1\",}}";
        Dictionary<int, MyObject> dict = Newtonsoft.Json.JsonConvert.DeserializeObject<Dictionary<int, MyObject>>(json);
        var count = dict.Keys.Count;
    }
}

public class MyObject
{
    public string survey_id { get; set; }
    public string device_id { get; set; }
}

对于这个例子，我简化了你的 json。所以它看起来像这样:

{
    "7407": {
        "survey_id": "406",
        "device_id": "1"
    },
    "7408": {
        "survey_id": "406",
        "device_id": "1"
    } 
}
