Vb.net 将JSON数据解析为对象列表

我是JSON新手，目前在解析对象列表中的JSON数据时遇到了一个难题

我试图解析的数据是由facebook graph api生成的，如下所示：

 {
  "100001621071794": {
    "id": "100001621071794",
    "name": "TEST1",
    "username": "test1",
    "link": "http://www.facebook.com/test1",
    "gender": "male",
    "picture": "http://profile.ak.fbcdn.net/test1.jpg"
    },
  "534237692": {
    "id": "534237692",
    "name": "TEST2",
    "username": "test2",
    "link": "http://www.facebook.com/test2",
    "gender": "female",
    "picture": "http://profile.ak.fbcdn.net/test2.jpg"
   }
}

Public Class FacebookUser  
  Public id As String  
  Public name As String  
  Public username As String  
  Public link As String  
  Public gender As String  
  Public picture As String  
End Class  

我使用以下代码来解析：

Dim MyFacebookUsers As List(Of FacebookUser) = MyTwitterSerializer.Deserialize(Of List(Of FacebookUser))(FBData)

FacebookUser类如下所示：

 {
  "100001621071794": {
    "id": "100001621071794",
    "name": "TEST1",
    "username": "test1",
    "link": "http://www.facebook.com/test1",
    "gender": "male",
    "picture": "http://profile.ak.fbcdn.net/test1.jpg"
    },
  "534237692": {
    "id": "534237692",
    "name": "TEST2",
    "username": "test2",
    "link": "http://www.facebook.com/test2",
    "gender": "female",
    "picture": "http://profile.ak.fbcdn.net/test2.jpg"
   }
}

Public Class FacebookUser  
  Public id As String  
  Public name As String  
  Public username As String  
  Public link As String  
  Public gender As String  
  Public picture As String  
End Class  

我知道这不是一个数组，因为它缺少“[”和“]”。但是当我用“[”和“]”替换“{”和“}”时，我得到了一个错误，因为一个invlaed矩阵

有人能给我指出正确的方向吗？

你说得对，那不是JSON数组，它是一个包含FacebookUser对象的对象，其中id值也是元素键

在.NET中，Dictionary类是JSON对象的等价物，因此可能类似于

Dim MyFacebookUsers As List(Of FacebookUser) = MyTwitterSerializer.Deserialize(Of Dictionary(Of FacebookUser))(FBData) 

这就是你需要的

正如您所发现的，仅通过更改大括号是无法将其转换为数组列表的。但是，如果您实际有一个数组，它将如下所示：

[
 {"id": "100001621071794",
  "name": "TEST1",
  "username": "test1",
  "link": "http://www.facebook.com/test1",
  "gender": "male",
  "picture": "http://profile.ak.fbcdn.net/test1.jpg"
  },
 {"id": "534237692",
  "name": "TEST2",
  "username": "test2",
  "link": "http://www.facebook.com/test2",
  "gender": "female",
  "picture": "http://profile.ak.fbcdn.net/test2.jpg"
  }
]

你的代码会很好的工作
