AppDomain.AssemblyLoad Event

Occurs when an assembly is loaded.

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

'Declaration
Public Event AssemblyLoad As AssemblyLoadEventHandler

Implements

_AppDomain.AssemblyLoad

The AssemblyLoadEventHandler delegate for this event indicates what assembly was loaded.

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.

The following sample demonstrates the AssemblyLoad event.

For this code example to run, you must provide the fully qualified assembly name. For information about how to obtain the fully qualified assembly name, see Assembly Names.
