## XmlSchemaComplexContentExtension class


Represents the **extension** element from XML [Schema](../) as specified by the World Wide [Web](../../system.web/) Consortium (W3C). This class is for complex types with complex content model derived by extension. It extends the complex type by adding attributes or elements.

```cpp
class XmlSchemaComplexContentExtension : public System::Xml::Schema::XmlSchemaContent
```

## Methods

| Method | Description |
| --- | --- |
| [get_AnyAttribute](./get_anyattribute/)() | Returns the [XmlSchemaAnyAttribute](../xmlschemaanyattribute/) component of the complex content model. |
| [get_Attributes](./get_attributes/)() | Returns the collection of attributes for the complex content. Contains [XmlSchemaAttribute](../xmlschemaattribute/) and [XmlSchemaAttributeGroupRef](../xmlschemaattributegroupref/) elements. |
| [get_BaseTypeName](./get_basetypename/)() | Returns the name of the complex type from which this type is derived by extension. |
| [get_Particle](./get_particle/)() | Returns one of the [XmlSchemaGroupRef](../xmlschemagroupref/), [XmlSchemaChoice](../xmlschemachoice/), [XmlSchemaAll](../xmlschemaall/), or [XmlSchemaSequence](../xmlschemasequence/) classes. |
| [set_AnyAttribute](./set_anyattribute/)(const SharedPtr\<XmlSchemaAnyAttribute\>\&) | Sets the [XmlSchemaAnyAttribute](../xmlschemaanyattribute/) component of the complex content model. |
| [set_BaseTypeName](./set_basetypename/)(const SharedPtr\<XmlQualifiedName\>\&) | Sets the name of the complex type from which this type is derived by extension. |
| [set_Particle](./set_particle/)(const SharedPtr\<XmlSchemaParticle\>\&) | Sets one of the [XmlSchemaGroupRef](../xmlschemagroupref/), [XmlSchemaChoice](../xmlschemachoice/), [XmlSchemaAll](../xmlschemaall/), or [XmlSchemaSequence](../xmlschemasequence/) classes. |
| [XmlSchemaComplexContentExtension](./xmlschemacomplexcontentextension/)() | Initializes a new instance of the [XmlSchemaComplexContentExtension](./) class. |
## Typedefs

| Typedef | Description |
| --- | --- |
| [Ptr](./ptr/) | An alias for shared pointer to an instance of this class. |
## Remarks



Objects of this class should only be allocated using [System::MakeObject()](../../system/makeobject/) function. Never create instances of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.
