部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
提供實作事件架構非同步模式的支援。 如需此模式的詳細資訊，請參閱事件架構非同步模式概觀。
protected:
void InvokeAsync(System::ServiceModel::ClientBase<TChannel>::BeginOperationDelegate ^ beginOperationDelegate, cli::array <System::Object ^> ^ inValues, System::ServiceModel::ClientBase<TChannel>::EndOperationDelegate ^ endOperationDelegate, System::Threading::SendOrPostCallback ^ operationCompletedCallback, System::Object ^ userState);
C#
protected void InvokeAsync(System.ServiceModel.ClientBase<TChannel>.BeginOperationDelegate beginOperationDelegate, object[] inValues, System.ServiceModel.ClientBase<TChannel>.EndOperationDelegate endOperationDelegate, System.Threading.SendOrPostCallback operationCompletedCallback, object userState);member this.InvokeAsync : System.ServiceModel.ClientBase<'Channel (requires 'Channel : null)>.BeginOperationDelegate * obj[] * System.ServiceModel.ClientBase<'Channel (requires 'Channel : null)>.EndOperationDelegate * System.Threading.SendOrPostCallback * obj -> unitProtected Sub InvokeAsync (beginOperationDelegate As ClientBase(Of TChannel).BeginOperationDelegate, inValues As Object(), endOperationDelegate As ClientBase(Of TChannel).EndOperationDelegate, operationCompletedCallback As SendOrPostCallback, userState As Object)- beginOperationDelegate
- ClientBase<TChannel>.BeginOperationDelegate
用來呼叫非同步作業的委派。
- inValues
- Object[]
非同步呼叫的輸入值。
- endOperationDelegate
- ClientBase<TChannel>.EndOperationDelegate
完成後用來結束非同步呼叫的委派。
- operationCompletedCallback
- SendOrPostCallback
完成非同步方法之後叫用的回呼 (由用戶端供應)。 回呼會傳遞至 ClientBase<TChannel>.BeginOperationDelegate。
- userState
- Object
要與非同步呼叫產生關聯的 userState 物件。
每次呼叫 userState 時，可以在 InvokeAsync(ClientBase<TChannel>.BeginOperationDelegate, Object[], ClientBase<TChannel>.EndOperationDelegate, SendOrPostCallback, Object) 參數中提供 GUID 或雜湊程式碼等唯一值，當每個作業完成時，事件處理常式就可以判斷哪一個作業執行個體引發了完成事件。
