如何反序列化的JSON数组和QUOT;根＆QUOT;元素使用Json.NET在阵列中的每个对象？ [英] How to deserialize JSON array with "root" element for each object in array using Json.NET?

问题描述

我有以下JSON字符串：

I have following JSON string:

[
  { "Person" : { "Name" : "John", "Gender" : "male" } },
  { "Person" : { "Name" : "John", "Gender" : "male" } }
]

（正如您可能会注意到不幸的是我有一种根元素的数组中的每个对象，对没有这个根元素的任务就变得十分简单了。）

(As you may notice unfortunately I have a sort of "root" element for each object in the array. Without this "root" element the task becomes quite trivial.)

我要反序列化到人类的列表：

I have to deserialize it into a list of Person class:

class Person {
    public string Name { get; set; }
    public string Gender { get; set; }
}
...
List<Person> ListPersons() {
    return JsonConvert.DeserializeObject<List<Person>>(jsonString);
}

是否有可能做 Json.NET 而无需创建包装类，像PersonResult？

Is it possible to do with Json.NET without creating wrapper class like PersonResult?

class PersonResult {
    public Person Person { get; set; }
}
...
List<Person> ListPersons() {
    return JsonConvert.DeserializeObject<List<PersonResult>>(jsonString)
                      .Select(p => p.Person)
                      .ToList();
}

对我来说，完美的解决方案是能够以某种方式显式地指定这个根（如通过属性），不产生任何包装，助手等。

The perfect solution for me is to be able somehow explicitly specify this "root" (e.g. via attribute) and do not create any wrappers, helpers, etc.

推荐答案

很遗憾，有没有什么可以做这个问题。这就是JSON格式的样子，并有周围没有办法。其结果是，Json.Net看到你的字符串作为或多或少：

Unfortunatelly, there's not much you can do about this issue. That's how JSON format looks like and there's no way around that. As a result, Json.Net "sees" your string as more or less:

的对象与人属性，这与名称另一个对象的数组和性别属性的

an array of objects with Person property, which is another object with Name and Gender properties

你可能玩一些自定义 ContractResolvers 强制序列化工作方式不同......但是这是相当多的工作。像你所说的包装类是如何将这些问题的处理，我建议坚持它。

You could possibly play some with custom ContractResolvers to force serializer to work differently... but that's quite a bit of work. Wrapper class like you suggested is how those problems are dealt with, and I suggest sticking to it.
