Newtonsoft反序列化Array以使用属性进行分类 [英] Newtonsoft deserialize Array to class with properties

问题描述

使用外部服务时，他们决定提供一个对象作为数组，其中每个属性都位于固定位置.喜欢

Consuming an external service where they decided to provide an object as an array where each property is on a fixed position. Like

{
    "persons" : [
        ["Luck", "Lucky", 28],
        ["Joe", "Dalton", 30],
        ["Jack", "Dalton", 28],
        ["William", "Dalton", 26],
        ["Averell", "Dalton", 24]
    ]
}

我想将其反序列化为人员列表".

I would like to deserialize this to a List of Person.

var persons =  JsonConvert.DeserializeObject<Person[]>(json);

class Person {
      public string FirstName {get; set; }
      public string LastName {get; set; }
      public int Age{get; set; }
}

是否有一种简单的方法(属性注释)来执行此操作，还是会写一个自定义序列化程序?

Is there an easy way (property annotation) to do this, or will it come down to write a custom serialiser?

由于大多数答案都缺少问题的实质.

Since most answers are missing the essence of the question.

如果这很容易

  {
    "persons" : [
        { 
             "FirstName" :  "Luck", 
             "LastName" : "Lucky", 
             "Age" : 28 
        },
        // ...
    ]
}

但事实并非如此.

推荐答案

persons属性是字符串数组的数组.尝试先反序列化为List<List<string>>

persons property is array of arrays of strings. Try to deserialize to List<List<string>> first

public class Root
{
    public List<List<string>> persons { get; set; }
}

，然后使用List<Person>列表"rel =" nofollow noreferrer> Select 方法

and then convert it to list of List<Person> using Select method

var root = JsonConvert.DeserializeObject<Root>(jsonString);
var persons = root.persons
    .Select(l => new Person { FirstName = l[0], LastName = l[1], Age = int.Parse(l[2]) })
    .ToList();
