使用C#反序列化复杂的JSON对象 [英] Deserialize complex JSON object using c#

问题描述

我知道如何反序列化基本Json对象.我对嵌套对象有疑问；例如，这是我要反序列化的json示例.

I know how to deserialize basic Json object. I am having a problem with nested objects; for example, here is an example json i want to deserialize.

{
    "data": {
        "A": {
            "id": 24,
            "key": "key",
            "name": "name",
            "title": "title"
        },
        "B": {
            "id": 37,
            "key": "key",
            "name": "name",
            "title": "title"
        },
        "C": {
            "id": 18,
            "key": "key",
            "name": "name",
            "title": "title"
        },
        "D": {
            "id": 110,
            "key": "key",
            "name": "name",
            "title": "title"
        }
      },
    "type": "type",
    "version": "1.0.0"
}

现在"data"具有未知数量的对象，可以是100，可以是1000或可以只是1，并且所有这些都具有不同的名称.我的最终目标是获取数据中每个对象的信息.

Now "data" has an unknown number of objects, could be 100 could be 1000 or could be just 1 and all of them with different name. My ultimate goal is to get the information of each object inside data.

我尝试了基本的json，但根本没有用.

I tried basic json but didn't work at all.

无论如何，这就是我尝试过的...

Anyways, this is what I have tried...

我创建了一个名为data的类

I made class called data

public class data
{
    public long id { get; set; }
    public string key { get; set; }
    public string name { get; set; }
    public string title { get; set; }
}

然后我做了另一个叫做test的课

then I made another class called test

public class test
{
    /*
    I have also tried this, which works but then I don't know what to do with it and how to deserialize the information of it.
    //public Newtonsoft.Json.Linq.JContainer data { get; set; }
    */
    public List<List<data>> data { get; set; }
    public string type { get; set; }
    public string version { get; set; }
}

在我的驱动程序应用程序中，我做到了

and in my driver application I did this

 string downloadedData = w.DownloadString(link);
 test t = JsonConvert.DeserializeObject<test>(downloadedData);

但是，这没有达到我的预期. 任何帮助将不胜感激.

But this didn't work as I expected to. Any help would be appreciated.

推荐答案

您正在寻找字典.

使用它作为您的类定义:

Use this as your class definition:

public class Rootobject
    {
        public Dictionary<string, DataObject> data { get; set; }
        public string type { get; set; }
        public string version { get; set; }
    }
    public class DataObject
    {
        public int id { get; set; }
        public string key { get; set; }
        public string name { get; set; }
        public string title { get; set; }
    }

这表明读取对象是可行的:

And this demonstrates that reading your object works:

var vals = @"{

""data"": {
    ""A"": {
        ""id"": 24,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    },
    ""B"": {
        ""id"": 37,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    },
    ""C"": {
        ""id"": 18,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    },
    ""D"": {
        ""id"": 110,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    }
  },
""type"": ""type"",
""version"": ""1.0.0""
}";
var obj = JsonConvert.DeserializeObject<Rootobject>(vals);
