Beispiele

Das folgende Beispiel veranschaulicht die AssemblyLoad Ereignis.The following sample demonstrates the AssemblyLoad event.

Für dieses Codebeispiel ausführen müssen Sie den vollqualifizierten Assemblynamen angeben.For this code example to run, you must provide the fully qualified assembly name. Informationen dazu, wie Sie den vollqualifizierten Assemblynamen abzurufen, finden Sie unter Assemblynamen.For information about how to obtain the fully qualified assembly name, see Assembly Names.

Hinweise

Die AssemblyLoadEventHandler Delegat für dieses Ereignis gibt an, welche Assembly geladen wurde.The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.

Um einen Ereignishandler für dieses Ereignis zu registrieren, benötigen Sie die erforderlichen Berechtigungen, oder ein SecurityException ausgelöst.To register an event handler for this event, you must have the required permissions, or a SecurityException is thrown.

Weitere Informationen zur Behandlung von Ereignissen finden Sie unter behandeln und Auslösen von Ereignissen.For more information about handling events, see Handling and Raising Events.
