GetCustomAttributes(Type, Boolean)

Sumber:

Module.cs

Mendapatkan atribut kustom dari jenis yang ditentukan.

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

Jenis atribut yang akan didapatkan.

inherit

Boolean

Argumen ini diabaikan untuk objek tipe ini.

Mengembalikan

Object[]

Array jenis Object yang berisi semua atribut kustom dari jenis yang ditentukan.

Penerapan

GetCustomAttributes(Type, Boolean)

Pengecualian

ArgumentNullException

attributeTypeadalah null.

ArgumentException

attributeType bukan objek yang Type disediakan oleh runtime. Misalnya, attributeType adalah TypeBuilder objek .
