XmlSchemaComplexContentRestriction Class

 

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)

public ref class XmlSchemaComplexContentRestriction : XmlSchemaContent

NameDescription
System_CAPS_pubmethodXmlSchemaComplexContentRestriction()

Initializes a new instance of the XmlSchemaComplexContentRestriction class.

NameDescription
System_CAPS_pubpropertyAnnotation

Gets or sets the annotation property.(Inherited from XmlSchemaAnnotated.)

System_CAPS_pubpropertyAnyAttribute

Gets or sets the XmlSchemaAnyAttribute component of the complex content model.

System_CAPS_pubpropertyAttributes

Gets the collection of attributes for the complex type. Contains the XmlSchemaAttribute and XmlSchemaAttributeGroupRef elements.

System_CAPS_pubpropertyBaseTypeName

Gets or sets the name of a complex type from which this type is derived by restriction.

System_CAPS_pubpropertyId

Gets or sets the string id.(Inherited from XmlSchemaAnnotated.)

System_CAPS_pubpropertyLineNumber

Gets or sets the line number in the file to which the schema element refers.(Inherited from XmlSchemaObject.)

System_CAPS_pubpropertyLinePosition

Gets or sets the line position in the file to which the schema element refers.(Inherited from XmlSchemaObject.)

System_CAPS_pubpropertyNamespaces

Gets or sets the XmlSerializerNamespaces to use with this schema object.(Inherited from XmlSchemaObject.)

System_CAPS_pubpropertyParent

Gets or sets the parent of this XmlSchemaObject.(Inherited from XmlSchemaObject.)

System_CAPS_pubpropertyParticle

Gets or sets one of the XmlSchemaGroupRef, XmlSchemaChoice, XmlSchemaAll, or XmlSchemaSequence classes.

System_CAPS_pubpropertySourceUri

Gets or sets the source location for the file that loaded the schema.(Inherited from XmlSchemaObject.)

System_CAPS_pubpropertyUnhandledAttributes

Gets or sets the qualified attributes that do not belong to the current schema's target namespace.(Inherited from XmlSchemaAnnotated.)

NameDescription
System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

The following example creates a complexContent element extended by restriction.
