从 VB.net 调用 Java 网络服务 (wsdl)

Calling Java webservice (wsdl) from VB.net

下面是我的javawsdl,我需要通过这个wsdl传递参数purchase和item。

我无法将带有列表类型参数的项目从 vb.net 传递给那个 wsdl,下面是我的 vb.net 代码

Imports System.Xml
Imports Ext.Net
Imports System.Xml.Serialization

Public Class WebForm1

    Inherits System.Web.UI.Page
    Private wsCreatePO As New CreatePO.PurchaseorderService
    Dim wsItem As New CreatePO.item

    Structure sItem
        Public poitem As String
        Public material As String
        Public plant As String
        Public qty As Int16
        Public valType As String
    End Structure


    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

       Dim array(4) As sItem
        array(0).poitem = "10"
        array(1).material = "NONSTOCK-MATERIAL"
        array(2).plant = "3012"
        array(3).qty = 10
        array(4).valType = "NEW"

        Dim purchases As New CreatePO.purchase

        purchases.compCode = "3000"
        purchases.docType = "ZCKT"
        purchases.vendor = ""
        purchases.purchOrg = "3000"
        purchases.purchGroup = "3ST"
        purchases.currency = "IDR"
        purchases.docDate = "20150603"
        purchases.supplyPlant = "3011"
        purchases.item = array

        Dim response As New CreatePO.responsePO

        response = wsCreatePO.createpo(purchases)

    End Sub

End Class

第 "purchases.item = array" 行的变量 'array' 上有一个错误标记,表示

"value of type '1-dimensional-array of WebApplication1.WebForm1.sItem' cannot be converted to '1-dimensional-array of WebApplication1.CreatePO.item' because 'WebApplication1.WebForm1.sItem' is not derived from 'WebApplication1.CreatePO.item'

我会去掉你的 array 变量并按照以下方式尝试:

Dim allItems As New List(Of CreatePO.item)

allItems.Add(new CreatePO.item With {.material = "Item 1 material",
                                     .plant = "Item 1 plant",
                                     .qty = 10})

purchases.item = allItems.ToArray()

然后您可以通过多次调用 .Add(如果需要)来添加多个项目。
