Comment résoudre ce problème alors que la valeur json générée de type ne peut pas être convertie en system.collections.generic.list ? .

[ad_1]

Salut.

J’ai une erreur lors de la génération Json. L’erreur est que la valeur de type « ValueAddedService » ne peut pas être convertie en System.Collections.Generic.List (Of ValueAddedService) »
De plus, la date et l’heure sont “messageDateTime =”\/Date(1674459281468)\/” et ne sont pas au format date/heure comme “2023-01-19T11:20:27+08:00”.
veuillez me conseiller concernant les deux problèmes ci-dessus

Merci

Madeen

Ce que j’ai essayé :

VB
Dim root As List(Of Root) = New List(Of Root)()

 Dim PickupAddress As PickupAddress = New PickupAddress With {
         .name = "xxy Company LTD",
         .address1 = "1, 11,13, Jalan Rajawali",
         .address2 = "Bandar Puchong Jaya",
         .city = "Puchong",
         .country = "MY",
         .district = "Puchong",
         .state = "Selangor",
         .postCode ="47000",
         .email = "sales@xxy.com",
         .phone = "069076 1651"
     }
 Dim shipperAddress As ShipperAddress = New ShipperAddress With {
         .name = "xxy Company LTD",
         .address1 = "1, 11,13, Jalan Rajawali",
         .address2 = "Bandar Puchong Jaya",
         .city = "Puchong",
         .country = "MY",
         .district = "Puchong",
         .state = "Selangor",
         .postCode ="47000",
         .email = "sales@xxy.com",
         .phone = "069076 1651"
     }
 Dim consignement As ConsigneeAddress = New ConsigneeAddress With {
         .name = "Poliklinik Gunwant",
         .address1 =  "Lot 9797, Jalan Menteri",
         .address2 = "Sungai Besar Selangor",
         .city = "Sungai Besar",
         .state = "Selangor",
         .district = "Sungai Besar",
         .country = "MY",
         .postCode = "46000",
         .email = "",
         .phone = "092548 3257"
 }

 Dim valADDService As ValueAddedService = New ValueAddedService With {
                        .vasCode = "PPOD"}

 Dim valueAddedServices As List(Of ValueAddedServices) = New List(Of ValueAddedServices)()
 valueAddedServices.Add(New ValueAddedServices With {.valueAddedService = valADDService})

 Dim shipmentPieces As List(Of ShipmentPiece) = New List(Of ShipmentPiece)()
 shipmentPieces.Add(New ShipmentPiece With {
           .pieceID = "1"})

 Dim shipItem As List(Of ShipmentItem) = New List(Of ShipmentItem)()
 shipItem.Add(New ShipmentItem With {
     .consigneeAddress = consignement,
     .shipmentID = "123456789",
     .packageDesc = "abc",
     .totalWeight = "1",
     .totalWeightUOM = "KG",
     .dimensionUOM = "CM",
     .productCode = "PDO",
     .currency = "USD",
     .remarks = "",
     .isMult = "true",
     .deliveryOption = "C",
     .shipmentPieces = shipmentPieces
 })

 Dim hdr As Hdr = New Hdr With {
 .accessToken ="123456789",
 .messageDateTime ="\/Date(1674459281468)\/",
 .messageLanguage = "en",
 .messageType = "SHIPMENT",
 .messageVersion = "1.4"
 }
 Dim bd As Bd = New Bd With {
     .pickupAccountId = "123587",
     .soldToAccountId = "325784",
     .pickupDateTime = "\/Date(1674459281468)\/",
     .handoverMethod = "1",
     .pickupAddress = PickupAddress,
     .shipperAddress = shipperAddress,
     .shipmentItems = shipItem
     }

 Dim manifesto As ManifestRequest = New ManifestRequest With {
    .bd = bd,
    .hdr = hdr
 }
 root.Add(New Root With {
 .manifestRequest = manifesto
 })

 Dim serializer As JavaScriptSerializer = New JavaScriptSerializer()
 v_jsonData = ""
 v_jsonData = serializer.Serialize(root)
 Me.txtJsonData.Text = serializer.Serialize(root)

Le résultat devrait être ci-dessous.

Solution 1

Exécutez votre code via un convertisseur de classe JSON et il produira les structures suivantes :

Public Class Bd
    Public Property pickupAccountId As String
    Public Property soldToAccountId As String
    Public Property pickupDateTime As DateTime
    Public Property handoverMethod As Integer
    Public Property pickupAddress As PickupAddress
    Public Property shipperAddress As ShipperAddress
    Public Property shipmentItems As List(Of ShipmentItem)
End Class

Public Class ConsigneeAddress
    Public Property name As String
    Public Property address1 As String
    Public Property address2 As String
    Public Property city As String
    Public Property state As String
    Public Property district As String
    Public Property country As String
    Public Property postCode As String
    Public Property phone As String
    Public Property email As String
End Class

Public Class Hdr
    Public Property messageType As String
    Public Property messageDateTime As DateTime
    Public Property accessToken As String
    Public Property messageVersion As String
    Public Property messageLanguage As String
End Class

Public Class ManifestRequest
    Public Property hdr As Hdr
    Public Property bd As Bd
End Class

Public Class PickupAddress
    Public Property name As String
    Public Property address1 As String
    Public Property address2 As String
    Public Property city As String
    Public Property state As String
    Public Property district As String
    Public Property country As String
    Public Property postCode As String
    Public Property phone As String
    Public Property email As String
End Class

Public Class Root
    Public Property manifestRequest As ManifestRequest
End Class

Public Class ShipmentItem
    Public Property consigneeAddress As ConsigneeAddress
    Public Property shipmentID As String
    Public Property packageDesc As String
    Public Property totalWeight As Integer
    Public Property totalWeightUOM As String
    Public Property dimensionUOM As String
    Public Property productCode As String
    Public Property currency As String
    Public Property remarks As String
    Public Property isMult As String
    Public Property valueAddedServices As ValueAddedServices
    Public Property deliveryOption As String
    Public Property shipmentPieces As List(Of ShipmentPiece)
End Class

Public Class ShipmentPiece
    Public Property pieceID As Integer
End Class

Public Class ShipperAddress
    Public Property name As String
    Public Property address1 As String
    Public Property address2 As String
    Public Property city As String
    Public Property state As String
    Public Property district As String
    Public Property country As String
    Public Property postCode As String
    Public Property phone As String
    Public Property email As String
End Class

Public Class ValueAddedService
    Public Property vasCode As String
End Class

Public Class ValueAddedServices
    Public Property valueAddedService As List(Of ValueAddedService)
End Class

Ainsi, la désérialisation JSON s’attend à renvoyer une instance de Root qui contient un ManifestRequest, pas une collection – qui est contenue dans une sous-classe.

Lorsque vous désérialisez JSON, vous obtenez toutes les données, pas seulement celles qui pourraient vous intéresser !

Solution 3

Vous essayez de désérialiser une seule instance de ValueAddedService et de la transmettre à l’API. Ce serait bien si vous travailliez avec une seule instance, mais vous désérialisez en fait dans une liste que vous envoyez à l’API.
