XmlSchemaObject XmlSchemaObject XmlSchemaObject XmlSchemaObject Class

Определение

Представляет корневой класс для иерархии модели объектов схемы XML, а также выступает в качестве базового класса для таких классов, как XmlSchema.Represents the root class for the Xml schema object model hierarchy and serves as a base class for classes such as the XmlSchema class.
