XmlSchemaComplexContentRestriction Class

Represents the restriction element from XML Schema as specified by the . This class is for complex types with a complex content model derived by restriction. It restricts the contents of the complex type to a subset of the inherited complex type.

Namespace: System.Xml.Schema
Assembly: System.Xml (in system.xml.dll)

public ref class XmlSchemaComplexContentRestriction : public XmlSchemaContent
public class XmlSchemaComplexContentRestriction extends XmlSchemaContent
public class XmlSchemaComplexContentRestriction extends XmlSchemaContent
Not applicable.

The following example creates a complexContent element extended by restriction.
