FieldInfo.IsNotSerialized-Eigenschaft

Ruft einen Wert ab, der angibt, ob dieses Feld über das NotSerialized-Attribut verfügt.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property IsNotSerialized As Boolean
'Usage
Dim instance As FieldInfo
Dim value As Boolean

value = instance.IsNotSerialized

public bool IsNotSerialized { get; }

public:
virtual property bool IsNotSerialized {
    bool get () sealed;
}

/** @property */
public final boolean get_IsNotSerialized ()

public final function get IsNotSerialized () : boolean

Eigenschaftenwert

true, wenn für das Feld das NotSerialized-Attribut festgelegt ist, andernfalls false.

Hinweise

Die IsNotSerialized-Eigenschaft gibt true zurück, wenn das Feld mit dem FieldAttributes.NotSerialized-Flag gekennzeichnet ist. Durch Festlegen dieses Flags für ein Feld wird angegeben, dass das Feld nicht serialisiert werden muss, wenn der Typ remote verwendet wird.

Beispiel

Im folgenden Beispiel werden die Feldinformationen der Felder von MyClass abgerufen. Außerdem wird bestimmt, ob die Felder serialisiert werden können, und die Ergebnisse werden angezeigt.
