Provides custom formatting for XML serialization and deserialization.
Assemblies: System.Xml.XmlSerializer (in System.Xml.XmlSerializer.dll)
System.Xml (in System.Xml.dll)
System.Xml.ReaderWriter (in System.Xml.ReaderWriter.dll)
Thetype exposes the following members.
|GetSchema||This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return a null reference (Nothing in Visual Basic) (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class.|
|ReadXml||Generates an object from its XML representation.|
|WriteXml||Converts an object into its XML representation.|
There are two reasons to implement this interface. The first is to control how your object is serialized or deserialized by the XmlSerializer. For example, you can chunk data into bytes instead of buffering large data sets, and also avoid the inflation that occurs when the data is encoded using Base64 encoding. To control the serialization, implement the ReadXml and WriteXml methods to control the XmlReader and XmlWriter classes used to read and write the XML. For an example of this, see How to: Chunk Serialized Data.
The second reason is to be able to control the schema. To enable this, you must apply the XmlSchemaProviderAttribute to the serializable type, and specify the name of the static member that returns the schema. See the XmlSchemaProviderAttribute for an example.
A class that implements the interface must have a parameterless constructor. This is a requirement of the XmlSerializer class.
