GetCustomAttributes(Type, Boolean)

Source:

Module.cs

Obtiene los atributos personalizados del tipo especificado.

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()

Parámetros

attributeType

Type

Tipo de atributo que se va a obtener.

inherit

Boolean

Se omite este argumento para los objetos de este tipo.

Devoluciones

Object[]

Matriz de tipo Object que contiene todos los atributos personalizados del tipo especificado.

Implementaciones

GetCustomAttributes(Type, Boolean)

Excepciones

ArgumentNullException

attributeType es null.

ArgumentException

attributeType no es un objeto Type proporcionado por el tiempo de ejecución. Por ejemplo, attributeType es un objeto TypeBuilder.
