public void DefineUnmanagedResource (string resourceFileName);

member this.DefineUnmanagedResource : string -> unit

Public Sub DefineUnmanagedResource (resourceFileName As String)

Parametri

resourceFileName non trovata.

-oppure-

resourceFileName è una directory.

SecurityException

Il chiamante non dispone dell'autorizzazione richiesta.

Esempio

L'esempio seguente illustra una chiamata a DefineUnmanagedResource, passando un file di risorse esterno.

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 System.ArgumentException. È necessario unire più risorse non gestite con uno strumento, ad esempio l'utilità Microsoft ResMerge (non fornita con Common Language Runtime).

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.

Si applica a

DefineUnmanagedResource(Byte[])

Definisce una risorsa non gestita per questo assembly come BLOB opaco di 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())

Parametri

resource: Byte[]

BLOB opaco di byte che rappresenta la risorsa non gestita.

Eccezioni

ArgumentException

Una risorsa non gestita è stata definita in precedenza.

ArgumentNullException

resource è null.

SecurityException

Il chiamante non dispone dell'autorizzazione richiesta.

Esempio

Nell'esempio di codice seguente viene creata e associata una matrice di byte che rappresenta una risorsa non gestita a un assembly dinamico usando DefineUnmanagedResource.

/*
   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.
