GetCustomAttributes(Type, Boolean)

Zdroj:

Module.cs

Získá vlastní atributy zadaného typu.

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()

Parametry

attributeType

Type

Typ atributu, který chcete získat.

inherit

Boolean

Tento argument je ignorován pro objekty tohoto typu.

Návraty

Object[]

Pole typu Object obsahující všechny vlastní atributy zadaného typu.

Implementuje

GetCustomAttributes(Type, Boolean)

Výjimky

ArgumentNullException

attributeType je null.

ArgumentException

attributeType není Type objekt zadaný modulem runtime. Například attributeType je TypeBuilder objekt .
