Exemplos

O exemplo a seguir cria um desinstalador personalizado que herda a Installer classe . Na função substituída Uninstall , a UninstallAction enumeração é definida com base na entrada do usuário. Se a entrada for "n", o desinstalador personalizado não executará nenhuma ação no recurso no log de eventos inserido pelo usuário. Caso contrário, ele removerá o recurso do log de eventos.
