Comentarios

De forma predeterminada, una instantánea incluye todos los ensamblados que se encuentran a través de sondeo.By default, a shadow copy includes all assemblies found through probing. El método SetShadowCopyPath restringe la instantánea a los ensamblados de los directorios especificados por path.The SetShadowCopyPath method restricts the shadow copy to the assemblies in the directories specified by path.

El método SetShadowCopyPath no especifica directorios adicionales en los que buscar los ensamblados.The SetShadowCopyPath method does not specify additional directories to be searched for assemblies. Los ensamblados de los que se va a realizar una copia sombra ya deben estar en la ruta de búsqueda, por ejemplo, en BaseDirectory.Assemblies to be shadow-copied must already be located in the search path, for example under BaseDirectory. El método SetShadowCopyPath especifica las rutas de acceso de búsqueda de las que se pueden realizar instantáneas.The SetShadowCopyPath method specifies which search paths are eligible to be shadow-copied.

Este método establece la propiedad ShadowCopyDirectories de la AppDomainSetup interna asociada a esta instancia.This method sets the ShadowCopyDirectories property of the internal AppDomainSetup associated with this instance.

Para obtener más información sobre las instantáneas, vea Shadow Copying assemblies.For more information on shadow copying, see Shadow Copying Assemblies.
