使用不同的 JSON 响应答案

【问题标题】：Consuming Varying JSON Response使用不同的 JSON 响应

【问题描述】：

我无法理解如何将 JSON 字符串反序列化为从我正在调用的 API 返回的类...

通常，我复制返回的 JSON，然后在 Visual Studio 中将特殊的 JSON 粘贴到 Class。它通常可以完美运行。

但是，使用此 API，生成的类包含硬编码的值，下次我调用 API 时可能会有所不同...

这是从 API 返回的 JSON：

{"content":{"type":"getTips_answer","total":61,"scan":1,"tips":{"2360626":[["3","4","6","8","10","25"],["9","11","22","27","34","40"],["4","12","25","27","29","30"],["4","6","7","10","41","47"],["14","17","20","40","41","42"],["17","20","22","26","30","41"],["1","3","18","21","28","39"],["5","10","13","19","25","39"],["17","25","33","38","42","44"],["5","11","16","25","43","45"],["5","9","25","27","38","44"],["7","19","27","32","46","48"],["20","21","28","34","37","48"],["10","12","18","35","43","47"],["3","6","9","17","29","42"],["22","26","28","36","43","47"],["7","13","24","30","45","48"],["3","5","14","19","23","27"],["9","14","15","16","22","40"],["10","18","26","36","41","46"],["2","19","23","33","38","42"]],"2360710":[["1","15","17","21","25","33"]],"2361097":[["1","3","5","27","35","41"],["3","11","12","24","27","48"],["8","11","13","33","34","48"],["2","10","29","31","41","46"]],"2362535":[["10","15","33","35","36","44"],["5","8","11","18","26","44"]],"2363152":[["6","7","10","13","35","37"],["1","9","14","29","42","49"],["23","24","26","32","35","45"],["1","2","11","18","22","39"]],"2363573":[["8","11","16","18","34","36"],["12","13","23","25","27","35"],["2","7","13","23","41","49"],["3","6","9","15","21","41"],["9","10","16","20","30","34"],["15","18","40","44","46","48"]],"2363902":[["17","19","24","26","33","48"]],"2364026":[["8","17","20","33","34","47"]],"2364405":[["10","17","23","38","41","45"],["9","13","27","33","36","41"]],"2365222":[["4","5","7","9","18","24"],["10","12","16","26","43","45"],["1","5","24","26","43","47"],["11","12","17","20","36","48"],["3","11","13","17","20","27"],["2","6","28","38","42","46"],["9","13","19","20","25","31"],["2","5","7","8","25","27"],["1","19","21","23","33","36"],["17","19","23","33","38","47"],["14","27","28","32","39","42"],["18","26","30","32","42","46"]],"2365522":[["2","24","25","31","42","48"],["13","16","31","39","43","45"]],"2365651":[["7","20","22","35","40","41"],["5","13","20","30","43","47"],["5","16","18","31","34","44"],["6","8","15","17","44","45"],["7","11","26","27","29","47"]]},"success":true,"errors":[]}}

这是 Visual Studio 从上述 JSON 生成的类：

public class Rootobject
{
    public Content content { get; set; }
}

public class Content
{
    public string type { get; set; }
    public int total { get; set; }
    public int scan { get; set; }
    public Tips tips { get; set; }
    public bool success { get; set; }
    public object[] errors { get; set; }
}

public class Tips
{
    public string[][] _2360626 { get; set; }
    public string[][] _2360710 { get; set; }
    public string[][] _2361097 { get; set; }
    public string[][] _2362535 { get; set; }
    public string[][] _2363152 { get; set; }
    public string[][] _2363573 { get; set; }
    public string[][] _2363902 { get; set; }
    public string[][] _2364026 { get; set; }
    public string[][] _2364405 { get; set; }
    public string[][] _2365222 { get; set; }
    public string[][] _2365522 { get; set; }
    public string[][] _2365651 { get; set; }
}

我的问题是，如果您查看 Tips 类，它包含像 _2360626 这样的值，下次可能不会出现。

如何编写一个可以将这个字符串反序列化为“动态”的类？如果这是正确的描述？

谢谢

【解决方案1】：

只需将tips 声明为Dictionary<string,List<List<string>>>

var obj = JsonConvert.DeserializeObject<RootObject>(json); //Json.Net
//or
//var obj = new JavaScriptSerializer().Deserialize<RootObject>(json);

public class Content
{
    public string type { get; set; }
    public int total { get; set; }
    public int scan { get; set; }
    public Dictionary<string,List<List<string>>> tips { get; set; }
    public bool success { get; set; }
    public List<object> errors { get; set; }
}

public class RootObject
{
    public Content content { get; set; }
}

我认为您必须放弃在 C# 中创建静态类型类来建模此 JSON 的想法。 JSON（和 javascript）没有被输入，所以不能保证它总是适合这样的类（正如你所发现的那样）。

我建议使用您会在此处找到引用的 C# JSON 解析库之一： http://json.org/

JSON.Net (http://james.newtonking.com/pages/json-net.aspx) 听起来很流行。

在您的项目中链接它，然后使用它来动态解析您从 API 调用接收到的 JSON，然后对结果执行您需要执行的任何操作。
