Json 在 Vb 中反序列化嵌套对象(Newtonsoft)

Question

基本上，我正在尝试从API获取数据。

我的 JSON 是 ：

[
{
"id": 101,
"items": [
{
"id": 91,
"quantity": 141,
"size": "12",
"assigned": false,
"item": {
"pk": 27,
"title": "test title",
"description": "test description",
"designer": "designer",
"category": 4,
"size": "12,14,16",
"image": "media/products/indir.jpg",
"price": 31.0,
"resin_gr": 31.0
}
},
{
"id": 92,
"quantity": 18,
"size": "14",
"assigned": false,
"item": {
"pk": 26,
"title": "Bileklik 5",
"description": "bileklik",
"designer": "designer",
"category": 2,
"size": "12,14,16",
"image": "media/products/NB00316.png",
"price": 50.0,
"resin_gr": 14.0
}
}
]
}
]

我的课程是：

Public Class Orders
Public Property id As Integer
Public Property items As IEnumerable(Of OrderItems)
End Class
Public Class OrderItems
Public Property id As Integer
Public Property quantity As String
Public Property size As String
Public Property assigned As String
Public Property item As List(Of OrderProduct)
End Class
Public Class OrderProduct
Public Property pk As Integer
Public Property title As String
Public Property description As String
Public Property designer As String
Public Property category As String
Public Property size As String
Public Property image As String
Public Property price As String
Public Property resin_gr As String
End Class

我正在尝试像这样解析 JSON：

Dim result As IEnumerable(Of Orders) = JsonConvert.DeserializeObject(Of IEnumerable(Of Orders))(JSONDATA)

我在路径"[0].items[0].item.pk"，第 1 行，位置 86 上收到错误。

我试过什么：

我将订单.项目更改为列表，但没有任何变化。

我该怎么办呢？

Answer 1

Public Class Orders
Public ID As Integer
Public Items As IEnumerable(Of OrderItems)
End Class
Public Class OrderItems
Public ID As Integer
Public quantity As Integer
Public size As Integer
Public assigned As Boolean
Public Item As OrderProduct
End Class
Public Class OrderProduct
Public pk As Integer
Public title As String
Public description As String
Public designer As String
Public category As Integer
Public size As String
Public image As String
Public price As Double
Public resin_gr As Double
End Class

编辑：就像一位朋友评论的那样，这是有效的，因为您尝试在此处将对象解析为列表：

Public Property item As List(Of OrderProduct)

当它需要时

Public Item As OrderProduct

不知何故，我错过了这一点，并在为指定的 JSON 重新创建自定义对象时解决了这个问题。
