### <a id="VM_Managed_DAFUL_SplineFile_GetSchema"></a> GetSchema()

This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the  to the class.

```csharp
public override XmlSchema GetSchema()

```

#### Returns

XmlSchema

An  that describes the XML representation of the object that is produced by the  method and consumed by the  method.

#### Parameters

`reader` XmlReader

The  stream from which the object is deserialized.

### <a id="VM_Managed_DAFUL_SplineFile_WriteXml_System_Xml_XmlWriter_"></a> WriteXml(XmlWriter)

Converts an object into its XML representation.

```csharp
public override void WriteXml(XmlWriter writer)

```

#### Parameters

`writer` XmlWriter

The  stream to which the object is serialized.
