DataContract Json序列化程序和项集合中缺少括号
当我反序列化/序列化并将数据压缩为json格式时,我的项集合缺少括号,导致它在发布到web api时失败。 以下是正确格式的json,带[]括号DataContract Json序列化程序和项集合中缺少括号,json,vb.net,serialization,datacontractjsonserializer,Json,Vb.net,Serialization,Datacontractjsonserializer,当我反序列化/序列化并将数据压缩为json格式时,我的项集合缺少括号,导致它在发布到web api时失败。 以下是正确格式的json,带[]括号 { "basket": { "basket_platform_type": "in_store", "basket_currency": { "currency_id": 2, "currency_code": "ZAR" }, "b

这就是我得到的,我错过了篮子项目的[]

下面是我用于序列化的类和函数
Namespace Global.MyPrice
Public Class GetBasketPrice
Public Class Entity
Public Property entity_type As String
Public Property entity_id As Integer
Public Property branch_business_owner_code As String
Public Property branch_business_id As Integer
End Class
Public Class User
Public Property member_programme As String
Public Property member_number As String
End Class
Public Class Basket_Currency
Public Property currency_id As Integer
Public Property currency_code As String
End Class
Public Class Rootobject
Public Property basket As Basket
Public Property entity As Entity
Public Property user As User
End Class
Public Class Basket_Items
Public Property spaaza_product_id As Integer
Public Property retailer_product_code As String
Public Property retailer_item_code As String
Public Property item_quantity As Integer
Public Property item_price As Single
End Class
Public Class Basket
Public Property basket_platform_type As String
Public Property basket_currency As Basket_Currency
Public Property basket_items() As Basket_Items
Public Property retailer_basket_code As String
Public Property basket_total_price As Single
End Class
End Class
结束命名空间
这是序列化函数
Dim jsonstring As String
Dim stream1 As New MemoryStream()
Dim ser As New DataContractJsonSerializer(GetType(MyPrice.GetBasketPrice.Rootobject))
ser.WriteObject(stream1, MyPriceBasket)
stream1.Position = 0
Dim sr As New StreamReader(stream1)
Console.Write("JSON form of Person object: ")
jsonstring = sr.ReadToEnd()
Console.WriteLine(jsonstring)
“basket\u items”
的值是一个JSON数组,它是一个括号内的值列表:[value1,value2,…,valueN]
。根据DataContractJsonSerializer将“集合、字典和数组”映射到JSON数组。因此,您的basket\u项目
属性需要是某种类型的集合,例如列表(basket\u项目)
:
或者,如果您想使用数组而不是列表,则您的()
位于错误的位置。在VB.NET中定义数组值属性:
更多。这里的C在哪里??您正在使用VB
Public Class Basket
Public Property basket_platform_type As String
Public Property basket_currency As Basket_Currency
Public Property basket_items As List(Of Basket_Items)
Public Property retailer_basket_code As String
Public Property basket_total_price As Single
End Class
Public Property basket_items As Basket_Items()
