C＃属性值为Json Key Name

Posted 2021-04-17

我有这样的Json：

  {
  "Result": {
    "Bruce": {
      "City": "Gotham",
      "Age": 43
    },
    "Clark": {
      "City": "Metro",
      "Age": 43
    }
  }
}

当我反序列化它时，我需要以下类结构

    public class Clark
    {
        public string City { get; set; }
        public int Age { get; set; }
    }

    public class Bruce
    {
        public string City { get; set; }
        public int Age { get; set; }
    }

    public class Result
    {
        public Bruce Bruce { get; set; }
        public Clark Clark { get; set; }

    }

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

这意味着我需要创建特定的类，如Bruce，Clark等。是否可以反序列化这个Json而不是单独的Bruce，Clark等，我只有一个这样的Person类

    public class Person
    {
        public string Name { get; set; }
        public string City { get; set; }

        public int Age { get; set; }
    }
    public class Result
    {           
        public List<Person> Persons { get; set; }
    }

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

这样JSON变得像：

{
  "Result": {
    "Persons": [
      {
        "Name": "Bruce",
        "City": "Gotham",
        "Age": 43
      },
      {
        "Name": "Clark",
        "City": "Metro",
        "Age": 43
      }
    ]
  }
}

答案

你的Json描述了一个名为Result的属性的对象，即Dictionary<string, Person>。

所以你的类只需要看起来像：

public class Person
{
    public string Name { get; set; }
    public string City { get; set; }
    public int Age { get; set; }
}

public class RootObject
{
    public Dictionary<string, Person> Result { get; set; }
}
