O exemplo a seguir demonstra o evento AssemblyLoad.The following sample demonstrates the AssemblyLoad event.

Para este exemplo de código ser executado, você deve fornecer o nome de assembly totalmente qualificado.For this code example to run, you must provide the fully qualified assembly name. Para obter informações sobre como obter o nome totalmente qualificado do assembly, consulte nomes de assembly.For information about how to obtain the fully qualified assembly name, see Assembly Names.
