Affiliate Window API将列传递给服务导致应用程序崩溃（VB.net）

Question

这会导致崩溃，我不明白为什么？

我使用SOAP / WSDL的经验很少，我认为这可能就是为什么我不知道如何开始调试它。

Sub Main()
    Dim service As AWIN.ApiService = New AWIN.ApiService
    Dim columns As AWIN.getProductList
    Dim AWresults() As AWIN.Product
    Dim response As New AWIN.getProductListResponse
    Dim total As Integer
    Dim activerefine As AWIN.RefineByGroup
    Dim refine As AWIN.RefineByGroup

    Const token As String = "xxy"

    Dim UA As AWIN.UserAuthentication = New AWIN.UserAuthentication
    With UA
        .sApiKey = token
    End With
    service.UserAuthenticationValue = UA

    columns = New AWIN.getProductList
    Dim stringsofthings As String() = {"sId", "iCategoryId", "iMerchantId", "sMerchantProductId", "iAdult", "bHotpick", _
                               "iUpc", "iEan", "sMpn", "iIsbn", "sName", "sDescription", "sSpecification", _
                               "sPromotion", "sBrand", "sModel", "sAwDeepLink", "sAwThumbUrl", "sAwImageUrl", _
                               "sMerchantThumbUrl", "sMerchantImageUrl", "sDeliveryTime", "fPrice", "sCurrency", _
                               "fStorePrice", "fRrpPrice", "fDeliveryCost", "bWebOffer", "bPreOrder", "sWarranty"}

    columns.sColumnToReturn = stringsofthings
    response = service.getProductList(columns)

    For c = 0 To UBound(response.oProduct)
        ReDim Preserve AWresults(c)
        AWresults(c) = New AWIN.Product
        AWresults(c) = response.oProduct(c)
        Console.WriteLine(AWresults.ToString)
    Next
    Console.ReadLine()

End Sub
