UnreferencedObjectEventHandler Delegate

 

Represents the method that handles the UnreferencedObject event of an XmlSerializer.

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

type UnreferencedObjectEventHandler = 
    delegate of 
        sender:Object *
        e:UnreferencedObjectEventArgs -> unit

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Xml.Serialization.UnreferencedObjectEventArgs

An UnreferencedObjectEventArgs that contains the event data.

When you create an UnreferencedObjectEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see NIB: Events and Delegates

The UnreferencedObject event occurs only when you call the Deserialize method.

The following example adds an UnreferencedObjectEventHandler to an XmlSerializer. The event is handled by the Serializer_UnreferencedObject method. To run the example, cut and paste the following XML into a file named UnrefObj.xml.
