Commenti

fileName non deve essere uguale a quello di qualsiasi altro modulo persistente, risorsa gestita autonoma o il file manifesto autonomo.

Si presuppone che le risorse gestite nel file siano pubbliche.

Il file di risorse specificato deve trovarsi nella directory in cui verrà salvato l'assembly.

Nota

A partire da .NET Framework 2.0 Service Pack 1, questo membro non richiede ReflectionPermission più con il ReflectionPermissionFlag.ReflectionEmit flag. Vedere Problemi di sicurezza in Reflection Emit. Per usare questa funzionalità, l'applicazione deve essere destinato a .NET Framework 3.5 o versione successiva.

Commenti

fileName non deve essere uguale a quello di qualsiasi altro modulo persistente, risorsa gestita autonoma o il file manifesto autonomo.

È possibile specificare gli attributi per la risorsa gestita.

Il file di risorse specificato deve trovarsi nella directory in cui verrà salvato l'assembly.
