以下は、UPS配送ラベルを生成するためのコードです。これは、UPS開発者キットで提供されている.netサンプルに基づいています。私の問題は、下の太字で強調表示されている行にあります。「System.NullReferenceException：オブジェクト参照がオブジェクトのインスタンスに設定されていません。」というエラーがスローされます。
私が知っているのは、UPS APIがラベルへのリンクを返すようにする場合は、このLabelLinksIndicatorが必要であるということです。それ以外の場合は、出荷の詳細は返されますが、ラベルは返されません。UPSドキュメントの関連セクションは、私の質問の下部にあります。
このエラーを克服するために何をする必要がありますか？LabelLinksIndicatorに渡す必要のある値は、ドキュメントからはわかりません。1、true、および空の文字列を渡してみました。いずれの場合も同じエラー。エラーメッセージは、現在ではないオブジェクトをインスタンス化する必要があることを示しているようです。ただし、何をインスタンス化するかがわかりません。残念ながら、WebおよびUPS.comで入手できる情報はまばらです。
