Json反序列化Vb中的嵌套对象(Newtonsoft)
Json反序列化Vb中的嵌套对象(Newtonsoft)
提问于 2019-12-20 18:51:10
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
}
}
]
}
]我的类是：
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我尝试这样解析JSON：
Dim result As IEnumerable(Of Orders) = JsonConvert.DeserializeObject(Of IEnumerable(Of Orders))(JSONDATA)我在路径'.items.item.pk'，第1行，位置86上遇到错误。
我尝试过的：
我将orders.item更改为list，但没有任何更改。
我该怎么做呢？

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:就像一个朋友评论的那样，这是因为你试图在这里将一个对象解析为一个列表：
Public Property item As List(Of OrderProduct)在需要的时候
Public Item As OrderProduct不知何故，当我为指定的JSON重新创建自定义对象时，我忽略了这一点，并解决了这个问题。
