以下の SOAP 応答がC# クライアントで逆シリアル化されない理由を誰か説明してもらえますか? 「リモート サーバーが予期しない応答を返しました: (400) 不正な要求」FaultException
というメッセージが表示され、内部例外として「リモート サーバーがエラーを返しました: (400) 不正な要求」というメッセージが表示されます。System.ServiceModel.ProtocolException
System.Net.WebException
私のクライアント コードでは、svcutil.exe (サービス参照の追加) で定義された複数のコントラクトを使用しています。このリクエストでは、基本認証を使用します。
バインディングのコードは、応答 SOAP の下にあります。
