Definicja

Przestrzeń nazw:

System.Web.Services.Protocols

Zestaw:

System.Web.Services.dll

Kończy asynchroniczne wywołanie metody reprezentowanej przez bieżący LogicalMethodInfoelement .

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()

Parametry

target

Object

Wystąpienie metody Object , na którym ma wywołać metodę.

asyncResult

IAsyncResult

Zwrócony IAsyncResult z BeginInvoke(Object, Object[], AsyncCallback, Object)elementu .

Zwraca

Object[]

Tablica obiektów zawierających wartość zwracaną oraz dowolne parametry metody klasy pochodnej lub wszystkie.

Wyjątki

TargetException

Parametr target to null.

MemberAccessException

Obiekt wywołujący nie ma uprawnień do wywoływania metody.

TargetInvocationException

Wywołana metoda zgłasza wyjątek.
