Web サービス (C# - WSDL) で poInfoInquiry メソッドを呼び出そうとすると、操作 'poInfoInquiry' の応答メッセージの本文を逆シリアル化する際にエラーが発生します。日付を DateTime 型として渡しています。
私がキャッチした例外は以下のとおりです。
System.ServiceModel.CommunicationException: Error in deserializing body of reply message for operation 'poInfoInquiry'. --->
System.InvalidOperationException: There is an error in XML document (12, 13). --->
