Я давний программист, но довольно новичок в C# и XML (к сожалению, одновременно). В рамках проекта, над которым я работаю, мне нужно создать XML-файлы, представляющие счета-фактуры в соответствии со стандартом GS1. Корневой файл xsd содержит следующий сегмент:
<xs:complexType name="StandardBusinessDocument">
<xs:sequence>
<xs:element ref="StandardBusinessDocumentHeader" minOccurs="0"/>
<xs:any namespace="##other" processContents="lax"/>
</xs:sequence>
</xs:complexType>
Счет-фактура определен в другом файле Invoice.xsd.
Я запустил Xsd2Code для обоих файлов xsd по отдельности и могу нормально заполнять сгенерированные объекты. Я также вижу, что объект StandardBusinessDocument имеет свойство StandardBusinessDocumentHeader и свойство Any. Но я не могу понять, как присвоить объект Invoice свойству Any. Если я пишу xStandardBusinessDocument.Any = new Invoice.InvoiceType();, я получаю сообщение об ошибке: Cannot implicity convert type 'EDISalesInvoices.BusinessObjects.Invoice.InvoiceType' to 'System.Xml.XmlElement'.
Конечно, в конце я хочу иметь возможность сериализовать и получить одну выходную строку XML.
Спасибо
