XmlSchemaComplexContentRestriction Class

.NET Framework (current version)

Represents the restriction element from XML Schema as specified by the World Wide Web Consortium (W3C). 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)

Inheritance Hierarchy

System::Object
System.Xml.Schema::XmlSchemaObject
System.Xml.Schema::XmlSchemaAnnotated
System.Xml.Schema::XmlSchemaContent
System.Xml.Schema::XmlSchemaComplexContentRestriction

Syntax

C++

public ref class XmlSchemaComplexContentRestriction : XmlSchemaContent

Constructors

	Name	Description
	XmlSchemaComplexContentRestriction()	Initializes a new instance of the XmlSchemaComplexContentRestriction class.

Properties

	Name	Description
	Annotation	Gets or sets the annotation property.(Inherited from XmlSchemaAnnotated.)
	AnyAttribute	Gets or sets the XmlSchemaAnyAttribute component of the complex content model.
	Attributes	Gets the collection of attributes for the complex type. Contains the XmlSchemaAttribute and XmlSchemaAttributeGroupRef elements.
	BaseTypeName	Gets or sets the name of a complex type from which this type is derived by restriction.
	Id	Gets or sets the string id.(Inherited from XmlSchemaAnnotated.)
	LineNumber	Gets or sets the line number in the file to which the schema element refers.(Inherited from XmlSchemaObject.)
	LinePosition	Gets or sets the line position in the file to which the schema element refers.(Inherited from XmlSchemaObject.)
	Namespaces	Gets or sets the XmlSerializerNamespaces to use with this schema object.(Inherited from XmlSchemaObject.)
	Parent	Gets or sets the parent of this XmlSchemaObject.(Inherited from XmlSchemaObject.)
	Particle	Gets or sets one of the XmlSchemaGroupRef, XmlSchemaChoice, XmlSchemaAll, or XmlSchemaSequence classes.
	SourceUri	Gets or sets the source location for the file that loaded the schema.(Inherited from XmlSchemaObject.)
	UnhandledAttributes	Gets or sets the qualified attributes that do not belong to the current schema's target namespace.(Inherited from XmlSchemaAnnotated.)

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Examples

The following example creates a complexContent element extended by restriction.
