从UPS API调用中获取标签

Question

是否有人熟悉UPS Web服务DOTNET的API示例代码，我正在测试UPS API ShipWSSample的代码示例。我返回了跟踪号，但不确定如何从ShipmentResponse获取标签数据。该代码在我得到响应的上方引用了标签代码。

    Dim labelSpec As New LabelSpecificationType()
    Dim labelStockSize As New LabelStockSizeType()
    labelStockSize.Height = "6"
    labelStockSize.Width = "4"
    labelSpec.LabelStockSize = labelStockSize
    Dim labelImageFormat As New LabelImageFormatType()
    labelImageFormat.Code = "GIF"
    labelSpec.LabelImageFormat = labelImageFormat

    shipmentRequest.Shipment = shipment
    System.Net.ServicePointManager.SecurityProtocol = DirectCast(3072,   SecurityProtocolType)
    Dim shipmentResponse As ShipmentResponse = shpSvc.ProcessShipment(shipmentRequest)

任何帮助将不胜感激 迈克
