'Declaration
Public Property AllFiles As FileIOPermissionAccess
'Usage
Dim instance As FileIOPermission
Dim value As FileIOPermissionAccess

value = instance.AllFiles

instance.AllFiles = value

public FileIOPermissionAccess AllFiles { get; set; }

public:
property FileIOPermissionAccess AllFiles {
    FileIOPermissionAccess get ();
    void set (FileIOPermissionAccess value);
}

/** @property */
public FileIOPermissionAccess get_AllFiles ()

/** @property */
public void set_AllFiles (FileIOPermissionAccess value)

public function get AllFiles () : FileIOPermissionAccess

public function set AllFiles (value : FileIOPermissionAccess)

Eigenschaftenwert

Der Satz von E/A-Dateiflags für alle Dateien.

Diese Eigenschaft ruft den gewährten Zugriff auf alle Dateien auf den Laufwerken des lokalen Computers und des Netzwerks ab oder legt diesen fest.

Ein einzelner FileIOPermissionAccess-Wert kann auf die Verwendung einer bitweisen AND-Operation überprüft werden.
