AppDomain.DomainUnload Event

Occurs when an AppDomain is about to be unloaded.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public event EventHandler DomainUnload
/** @event */
public final void add_DomainUnload (EventHandler value)

/** @event */
public final void remove_DomainUnload (EventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The EventHandler delegate for this event can perform any termination activities before the application domain is unloaded.

Each application domain that needs to perform processing when it is unloaded should register an event handler for this event. A shared event handler should not be used, because the EventHandler delegate does not identify the domain that is being unloaded.

NoteNote

This event is never raised in the default application domain.

Do not make assumptions about the thread the event is raised on. The event can be raised on a different thread than the one that called the Unload method.

To register an event handler for this event, you must have the required permissions, or a SecurityException is thrown.

For more information about handling events, see Consuming Events.
