Tanım

Ad Alanı:

System.Web.Services.Protocols

Bütünleştirilmiş Kod:

System.Web.Services.dll

Bu LogicalMethodInfotarafından temsil edilen yöntemin zaman uyumsuz çağrısını başlatır.

public:
 IAsyncResult ^ BeginInvoke(System::Object ^ target, cli::array <System::Object ^> ^ values, AsyncCallback ^ callback, System::Object ^ asyncState);

public IAsyncResult BeginInvoke (object target, object[] values, AsyncCallback callback, object asyncState);

member this.BeginInvoke : obj * obj[] * AsyncCallback * obj -> IAsyncResult

Public Function BeginInvoke (target As Object, values As Object(), callback As AsyncCallback, asyncState As Object) As IAsyncResult

Parametreler

target

Object

yönteminin Object çağrıldığı örneği.

values

Object[]

Çağrılan yöntem için bir bağımsız değişken listesi. Bu, yöntemin parametreleriyle aynı sayı, sıra ve türe sahip bir nesne dizisidir. Yöntem herhangi bir parametre gerektirmiyorsa, values olmalıdır null.

callback

AsyncCallback

Zaman uyumsuz çağırma tamamlandığında çağrılacak temsilci. ise callback null, temsilci çağrılmıyordur.

asyncState

Object

Temsilciye iletilen durum bilgileri.

Döndürülenler

IAsyncResult

IAsyncResult Uzak yöntem çağrısından dönüş değerlerini almak için öğesine geçirilenEndInvoke(Object, IAsyncResult).

Özel durumlar

TargetException

target parametresidirnull.

ArgumentException

içindeki values parametrelerin sayısı, türü ve sırası çağrılan yöntemin imzası ile eşleşmiyor.

MemberAccessException

Çağıranın yöntemini çağırma izni yok.
