## XmlSchemaGroupRef class


Represents the **group** element with **ref** attribute from the XML [Schema](../) as specified by the World Wide [Web](../../system.web/) Consortium (W3C). This class is used within complex types that reference a **group** defined at the **schema** level.

```cpp
class XmlSchemaGroupRef : public System::Xml::Schema::XmlSchemaParticle
```

## Methods

| Method | Description |
| --- | --- |
| [get_Particle](./get_particle/)() | Returns one of the [XmlSchemaChoice](../xmlschemachoice/), [XmlSchemaAll](../xmlschemaall/), or [XmlSchemaSequence](../xmlschemasequence/) classes, which holds the post-compilation interpretation of the **Particle** value. |
| [get_RefName](./get_refname/)() | Returns the name of a group defined in this schema (or another schema indicated by the specified namespace). |
| [set_RefName](./set_refname/)(const SharedPtr\<XmlQualifiedName\>\&) | Sets the name of a group defined in this schema (or another schema indicated by the specified namespace). |
| [XmlSchemaGroupRef](./xmlschemagroupref/)() | Initializes a new instance of the [XmlSchemaGroupRef](./) 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.
