反序列化在C＃中嵌套的JSON数组 [英] Deserialize nested JSON array in C#

问题描述

我有一个JSON数组与嵌套的对象，再presenting菜单，就象这样：

I have a JSON array with nested objects, representing a menu, as this:

[
    [
      {
       "name": "Item 1",
       "id": 1
      },
      {
       "name": "Item 2",
       "id": 2,
       "children": [
        [
         {
          "name": "Item 21",
          "id": 21
         }
        ]
       ]
      },
      {
       "name": "Item 3",
       "id": 3,
       "children": [
        [
         {
          "name": "Item 31",
          "id": 31,
          "children": [
           [
            {
             "name": "Item 311",
             "id": 311
            },
            {
             "name": "Item 312",
             "id": 312
            }
           ]
          ]
         },
         {
          "name": "Item 32",
          "id": 32
         },
...

和我想用的JavaScriptSerializer反序列化它。我有一些code如下图所示，但不工作。

And I want to deserialize it using JavaScriptSerializer. I have some code as shown below but is not working.

var serializer = new JavaScriptSerializer();
var objects = serializer.Deserialize<Menu>(jsonData); 
...


public class Menu
    {
        public int id { get; set; }
        public string name { get; set; }
        public Menu[] children { get; set; }
    }

我得到的错误是类型菜单，不支持反序列化矩阵。
我想AP preciate如何申报自定义对象的任何帮助。

The error I get is "The type 'Menu' is not supported to deserialize a matrix". I would appreciate any help on how to declare the custom object.

干杯。

推荐答案

您根对象是一个2D的交错数组对象。属性孩子也2D交错数组。因此，你的菜单类必须是：

Your root object is a 2d jagged array of objects. The properties "children" are also 2d jagged arrays. Thus your Menu class needs to be:

public class Menu
{
    public int id { get; set; }
    public string name { get; set; }
    public Menu [][] children { get; set; }
}

和反序列化JSON如下：

And deserialize your JSON as follows:

var serializer = new JavaScriptSerializer();
var objects = serializer.Deserialize<Menu [][]>(jsonData);

另外，如果你preFER名单数组，这样做：

Alternatively, if you prefer lists to arrays, do:

public class Menu
{
    public int id { get; set; }
    public string name { get; set; }
    public List<List<Menu>> children { get; set; }
}

然后

var objects = serializer.Deserialize<List<List<Menu>>>(jsonData);
