FieldInfo.IsFamilyAndAssembly-Eigenschaft

Ruft einen Wert ab, der angibt, ob für dieses Feld die Sichtbarkeitsstufe FamilyAndAssembly definiert ist.

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

Syntax

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

value = instance.IsFamilyAndAssembly

public bool IsFamilyAndAssembly { get; }

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

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

public final function get IsFamilyAndAssembly () : boolean

Eigenschaftenwert

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

Hinweise

Wenn für ein Feld die Sichtbarkeitsstufe FamilyAndAssembly definiert ist, kann es ausschließlich von den Membern einer abgeleiteten Klasse innerhalb der gleichen Assembly aufgerufen werden, nicht jedoch von anderen Typen.

Die IsFamilyAndAssembly-Eigenschaft ist festgelegt, wenn das FieldAttributes.FamANDAssem-Attribut festgelegt ist.

Beispiel

Im folgenden Beispiel wird eine Klasse erstellt, und es werden der Klassenname, der Feldname und der IsFamilyAndAssembly-Eigenschaftenwert des Felds angezeigt.
