Comentarios
El estado anterior del permiso actual para el tipo de acceso especificado se sobrescribe. El código siguiente establece el acceso de C:\temp en Read.
fileIOPerm1->SetPathList(FileIOPermissionAccess::Read, "C:\\temp");
fileIOPerm1.SetPathList(FileIOPermissionAccess.Read, "C:\\temp");
fileIOPerm1.SetPathList(FileIOPermissionAccess.Read, "C:\\temp")
El código siguiente no sobrescribirá este acceso porque los tipos de acceso no son los mismos.
fileIOPerm1->SetPathList(FileIOPermissionAccess::Write, "C:\\documents");
fileIOPerm1.SetPathList(FileIOPermissionAccess.Write, "C:\\documents");
fileIOPerm1.SetPathList(FileIOPermissionAccess.Write, "C:\\documents")
