Beispiele

Im folgenden Beispiel wird das AssemblyLoad-Ereignis veranschaulicht.The following sample demonstrates the AssemblyLoad event.

Damit dieses Codebeispiel ausgeführt werden kann, müssen Sie den voll qualifizierten Assemblynamen angeben.For this code example to run, you must provide the fully qualified assembly name. Informationen zum Abrufen des voll qualifizierten Assemblynamens finden Sie unter Assemblynamen.For information about how to obtain the fully qualified assembly name, see Assembly Names.

   }

};

Hinweise

Der 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, müssen Sie über die erforderlichen Berechtigungen verfügen, oder es wird eine 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.
