反序列化在vb.net JSON数组 [英] Deserialize json array in vb.net

问题描述

我有被格式化JSON数组如下：

I have a json array which is formatted as follows:

[
  {
    "property":96,
    "listofstuff":[
      {
        "anotherproperty":"some text here",
        "yetanother":"text goes here too"
      }
    ],
    "lastproperty":3001
  },
 <rest of array>
]

我如何反序列化这一点，这样我可以有通过索引对象列表的方式财产？含义，我希望能够获得这样的数据： MYLIST（96）.lastproperty 或 MYLIST（96）.listofstuff.yetanother ，并将它返回正确的数据类型呢？是，甚至有可能在vb.net？

How can I deserialize this in such a way that I can have a list of objects indexed by property? Meaning, I want to be able to access the data like this: MyList(96).lastproperty or MyList(96).listofstuff.yetanother and have it return the proper datatype too? Is that even possible in vb.net?

推荐答案

我同意你需要使用JSON库Json.NET在的 HTTP：//json.$c$cplex.com/

I agree that the JSON library you need to use is Json.NET found at http://json.codeplex.com/

因此​​，考虑到你的榜样JSON数组，我做了如下类，可用于序列化和反序列化：

So, given your example JSON array, I made the following classes that can be used for serializing and deserializing:

Public Class Item
    Public Property [property]() As Integer
    Public Property listofstuff() As Stuff()
    Public Property lastproperty() As Integer
End Class

Public Class Stuff
    Public Property anotherproperty() As String
    Public Property yetanother() As String
End Class

然后，所有你需要的是下面的code到能够访问大致你想要的方式中的数据：

Then all you need is the following code to be able to access the data in roughly the way you wanted to:

Dim Items = Newtonsoft.Json.JsonConvert.DeserializeObject(Of Item())(json)
Dim MyList = Items.ToDictionary(Function(x) x.property)
Dim Stuff = MyList(96).listofstuff(0)

如果用 listofstuff 属性数组你的意图是要存储任何字符串一双然后用这个定义项目（你也不会需要的东西类）：

If your intent with the listofstuff property array was to store any string pair then use this definition for Item (and you also won't need the Stuff class):

Public Class Item
    Public Property [property]() As Integer
    Public Property listofstuff() As Dictionary(Of String, String)()
    Public Property lastproperty() As Integer
End Class
