XmlAttributes.XmlType Property

Gets or sets an object that specifies how the XmlSerializer serializes a class to which the XmlTypeAttribute has been applied.

Namespace:  System.Xml.Serialization
Assembly:  System.Xml (in System.Xml.dll)

Public Property XmlType As XmlTypeAttribute
Dim instance As XmlAttributes 
Dim value As XmlTypeAttribute 

value = instance.XmlType

instance.XmlType = value

Property Value

Type: System.Xml.Serialization.XmlTypeAttribute
An XmlTypeAttribute that overrides an XmlTypeAttribute applied to a class declaration.

The XmlTypeAttribute can be used to control how a type is serialized by the XmlSerializer. For example, by default, when a type is serialized, the XmlSerializer uses the class name as the XML element name. By creating an XmlTypeAttribute, setting the XmlType property to it, and creating an XmlAttributeOverrides object, you can change the XML element name.

The following example creates an XmlTypeAttribute object, and assigns it to the XmlType property of an XmlAttributes object.
