Commenti
Un assembly può essere associato a una sola risorsa non gestita. Ciò significa che la chiamata DefineVersionInfoResource o DefineUnmanagedResource dopo che uno dei metodi è stato chiamato in precedenza genererà l'eccezione System.ArgumentException. È necessario unire più risorse non gestite con uno strumento come l'utilità Microsoft ResMerge (non fornita con Common Language Runtime SDK).
Le stringhe di argomenti vuote vengono scritte come singolo spazio. Gli spazi vengono sostituiti con i caratteri Null nelle stringhe dell'argomento.
Le informazioni vengono dedotte dall'oggetto AssemblyName
utilizzato per definire questo assembly dinamico. Gli attributi personalizzati di questo assembly sostituiscono le informazioni specificate nell'oggetto AssemblyName
.

Un assembly può essere associato a una sola risorsa non gestita. Ciò significa che la chiamata DefineVersionInfoResource o DefineUnmanagedResource dopo che uno dei metodi è stato chiamato in precedenza genererà l'eccezione System.ArgumentException. È necessario unire più risorse non gestite con uno strumento come l'utilità Microsoft ResMerge
(non fornita con Common Language Runtime SDK).
Le stringhe di argomenti vuote vengono scritte come singolo spazio. Gli spazi vengono sostituiti con i caratteri Null nelle stringhe dell'argomento.
La struttura della risorsa della versione include dati che identificano la versione, la lingua e la distribuzione del file. I programmi di installazione usano le funzioni nella libreria di installazione file (VER.DLL) per recuperare la risorsa informazioni sulla versione da un file e per estrarre i blocchi di informazioni sulla versione dalla risorsa.
