LogicalMethodInfo.EndInvoke(Object, IAsyncResult) Método

Definición

Finaliza una invocación asincrónica del método representado por LogicalMethodInfo actual.

public:
 cli::array <System::Object ^> ^ EndInvoke(System::Object ^ target, IAsyncResult ^ asyncResult);
public object[] EndInvoke (object target, IAsyncResult asyncResult);
member this.EndInvoke : obj * IAsyncResult -> obj[]
Public Function EndInvoke (target As Object, asyncResult As IAsyncResult) As Object()

Parámetros

target
Object

Instancia de Object donde debe invocarse al método.

asyncResult
IAsyncResult

Interfaz IAsyncResult devuelta a partir del método BeginInvoke(Object, Object[], AsyncCallback, Object).

Devoluciones

Object[]

Matriz de objetos que contiene el valor devuelto, así como cualquiera de los parámetros de salida o por referencia del método de la clase derivada.

Excepciones

El parámetro target es null.

El llamador no tiene permiso para invocar al método.

El método invocado produce una excepción.
