我是一名尝试在eBay上列出Click＆amp; amp;产品的.Net开发人员。搜集。我的代码段是：
Dim ServiceOption As New ShippingServiceOptionsType()
ebayItem.ShippingDetails = New ShippingDetailsType() ebayItem.ShippingDetails.ShippingServiceOptions = New ShippingServiceOptionsTypeCollection()
ServiceOption.ShippingService = "PickUpDropOff"
ebayItem.AutoPay = True
ebayItem.PickupInStoreDetails = New PickupInStoreDetailsType() ebayItem.PickupInStoreDetails.EligibleForPickupDropOff = True ebayItem.ShippingDetails.ShippingServiceOptions.Add(ServiceOption)
ebayItem.PickupInStoreDetails.EligibleForPickupInStore = True
ebayItem.PickupInStoreDetails.EligibleForPickupInStoreSpecified = True
我收到错误消息 -
邮资服务Click＆amp; Collect（370）不可用。输入请求中的一个或多个参数值无效。检查ErrorParameters元素的响应以确定哪些参数具有无效值。更正这些值，然后重新发送输入请求。“
有谁知道我的代码中缺少什么？
