Remarques

Un assembly ne peut être associé qu’à une seule ressource non managée. Cela signifie que l’appel DefineVersionInfoResource ou DefineUnmanagedResource après l’appel de l’une des méthodes précédemment lève l’exception System.ArgumentException. Plusieurs ressources non managées doivent être fusionnées avec un outil tel que l’utilitaire Microsoft ResMerge (non fourni avec le Common Language Runtime).

Notes

À compter du .NET Framework 2.0 Service Pack 1, ce membre n’a plus besoin de ReflectionPermission l’indicateur ReflectionPermissionFlag.ReflectionEmit . (Consultez Problèmes de sécurité dans l’émission de réflexion.) Pour utiliser cette fonctionnalité, votre application doit cibler .NET Framework 3.5 ou version ultérieure.

S’applique à

DefineUnmanagedResource(Byte[])

public:
 void DefineUnmanagedResource(cli::array <System::Byte> ^ resource);
public void DefineUnmanagedResource (byte[] resource);
member this.DefineUnmanagedResource : byte[] -> unit
Public Sub DefineUnmanagedResource (resource As Byte())

Paramètres

resource
Byte[]

Objet blob d’octets opaque représentant la ressource non managée.

Exceptions

ArgumentException

Une ressource non managée a été définie précédemment.

ArgumentNullException

resource a la valeur null.

SecurityException

L'appelant n'a pas l'autorisation requise.

Exemples

L’exemple de code suivant crée et attache un tableau d’octets représentant une ressource non managée à un assembly dynamique, à l’aide DefineUnmanagedResourcede .

/*
   The following program demonstrates the 'DefineResource' and 'DefineUnmanagedResource'
   methods of 'AssemblyBuilder' class. It builds an assembly and a resource file at runtime.
   An unmanaged resource file is also defined for the same resource file. The EmittedTest2.cpp file
   calls the methods of "MyEmitAssembly.dll" assembly and the message is displayed to console.
