Comentarios

Un ensamblado solo se puede asociar a un recurso no administrado. Esto significa que la llamada a DefineVersionInfoResource o DefineUnmanagedResource después de llamar a uno de los métodos se llamó anteriormente producirá la excepción System.ArgumentException. Es necesario combinar varios recursos no administrados con una herramienta como la utilidad Microsoft ResMerge (no se proporciona con Common Language Runtime).

Nota

A partir de .NET Framework 2.0 Service Pack 1, este miembro ya no requiere ReflectionPermission con la ReflectionPermissionFlag.ReflectionEmit marca . (Consulte Problemas de seguridad en emisión de reflexión). Para usar esta funcionalidad, la aplicación debe tener como destino .NET Framework 3.5 o posterior.

Se aplica a

DefineUnmanagedResource(Byte[])

Define un recurso no administrado para este ensamblado como blob opaco de bytes.

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

Parámetros

resource
Byte[]

Blob opaco de bytes que representa el recurso no administrado.

Excepciones

ArgumentException

Se definió anteriormente un recurso no administrado.

ArgumentNullException

resource es null.

SecurityException

El llamador no dispone del permiso requerido.

Ejemplos

En el ejemplo de código siguiente se crea y se adjunta una matriz de bytes que representa un recurso no administrado a un ensamblado dinámico, mediante 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.
