如何将 JSON ARRAY 从 IRESTRESPONSE 转换为 C# 数组答案

【问题标题】：How to convert JSON ARRAY from IRESTRESPONSE to C# array如何将 JSON ARRAY 从 IRESTRESPONSE 转换为 C# 数组
【发布时间】：2019-07-12 09:35:10
【问题描述】：

我想知道一种将json 转换为数组以在c# winform 中处理的方法。这些是我的尝试，但已达到目标，此时我想获取数据，但我无法获取数据，因为我对 json 没有经验。

最后一个代码句子给我错误：

没有为“WindowsFormsApplication2.Person[]”类型定义无参数构造函数。

这是响应内容：

JSON

"{\"Results\":{\"output1\":[{\"Class\":\"10\",\"age\":\"9.06725552044283\",\"menopause\":\"18.5605772106407\",\"tumor-size\":\"5.62041822714077\",\"inv-nodes\":\"2.50477840015836\",\"node-caps\":\"5.29640554298695\",\"deg-malig\":\"1.77286724180295\",\"breast\":\"2.67776376618299\",\"breast-quad\":\"5.61570098311485\",\"irradiat\":\"4.84969010222608\",\"Scored Labels\":\"1\",\"Scored Probabilities\":\"0.999995118824755\"}]}}"

类

public class Person
{
    public string Class { get; set; }
    public string age { get; set; }

    public string menopause { get; set; }
    public string tumor_size { get; set; }

    public string inv_nodes { get; set; }
    public string node_caps { get; set; }

    public string deg_malig { get; set; }
    public string breast { get; set; }

    public string breast_quad { get; set; }
    public string irradiat { get; set; }

    public string output { get; set; }
    public string possiblity { get; set; }
}

IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content.ToString());

JavaScriptSerializer js = new JavaScriptSerializer();
var yourOjbect = new JavaScriptSerializer().DeserializeObject(response.Content);
Person[] persons = js.Deserialize<Person[]>(response.Content);

【问题讨论】：

您是否尝试过使用 Newtonsoft.Json 库来反序列化您的响应？
你的json是一个带有Results属性的对象，它返回一个带有output1属性的对象，然后包含数组。所以你的对象结构需要反映这一点
你可以试试这个：var yourOjbect = js.DeserializeObject(response.Content); 并为Person 类定义一个空的构造函数。
@RahulSharma person 类已经有一个（隐式）空构造函数。明确表示无济于事。
使用 Newtonsoft 库，一个使用 dynamic 属性的 JSON 字符串的示例工作小提琴：dotnetfiddle.net/3hOWWu

【解决方案1】：

对于您的特定 JSON 字符串，您可以使用解决方案中提供的 Model 类，并且正在完成反序列化过程：

一个工作演示在这里：https://dotnetfiddle.net/2VsyYL

using System;
using Newtonsoft.Json;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        string json=@"{'Results':{'output1':[{'Class':'10','age':'9.06725552044283','menopause':'18.5605772106407','tumor-size':'5.62041822714077','inv-nodes':'2.50477840015836','node-caps':'5.29640554298695','deg-malig':'1.77286724180295','breast':'2.67776376618299','breast-quad':'5.61570098311485','irradiat':'4.84969010222608','Scored Labels':'1','Scored Probabilities':'0.999995118824755'}]}}";
        var Sresponse = JsonConvert.DeserializeObject<RootObject>(json);

        foreach(var result in Sresponse.Results.output1)
        {    
            Console.WriteLine(result.Class);
            Console.WriteLine(result.age);
            Console.WriteLine(result.deg_malig);
            Console.WriteLine(result.Scored_Labels);

        }       
    }
}

public class Results
{
    public List<Output1> output1 { get; set; }
}

public class RootObject
{
    public Results Results { get; set; }
}


public class Output1
{
    public string Class { get; set; }
    public string age { get; set; }
    public string menopause { get; set; }

    [JsonProperty("tumor-size")]
    public string tumor_size { get; set; }

    [JsonProperty("inv-nodes")]
    public string inv_nodes { get; set; }

    [JsonProperty("node-caps")]
    public string node_caps { get; set; }

    [JsonProperty("deg-malig")]
    public string deg_malig { get; set; }

    public string breast { get; set; }

    [JsonProperty("breast-quad")]
    public string breast_quad { get; set; }

    public string irradiat { get; set; }

    [JsonProperty("Scored Labels")]
    public string Scored_Labels { get; set; }

    [JsonProperty("Scored Probabilities")]
    public string Scored_Probabilities { get; set; }
}

这将输出：

10
9.06725552044283
1.77286724180295
1
