GetCustomAttributes(Type, Boolean)

Quelle:

Module.cs

Ruft benutzerdefinierte Attribute des angegebenen Typs ab.

public:
 virtual cli::array <System::Object ^> ^ GetCustomAttributes(Type ^ attributeType, bool inherit);

public virtual object[] GetCustomAttributes (Type attributeType, bool inherit);

abstract member GetCustomAttributes : Type * bool -> obj[]
override this.GetCustomAttributes : Type * bool -> obj[]

Public Overridable Function GetCustomAttributes (attributeType As Type, inherit As Boolean) As Object()

Parameter

attributeType

Type

Der Typ der abzurufenden Attribute.

inherit

Boolean

Dieses Argument wird für Objekte dieses Typs ignoriert.

Gibt zurück

Object[]

Ein Array vom Typ Object mit allen benutzerdefinierten Attributen vom angegebenen Typ.

Implementiert

GetCustomAttributes(Type, Boolean)

Ausnahmen

ArgumentNullException

attributeType ist null.

ArgumentException

attributeType ist kein Type-Objekt, das von der Laufzeit bereitgestellt wird. Beispielsweise ist attributeType ein TypeBuilder-Objekt.
