WorkflowCreationContext.OnBeginWorkflowCompleted 方法

定義

命名空間:
System.ServiceModel.Activities
組件:
System.ServiceModel.Activities.dll

開始非同步操作以執行工作流程實例完成通知。 當與此 WorkflowCreationContext 相關聯的工作流程實例完成時，會呼叫此方法。 衍生類別可以覆寫此操作，對工作流程實例完成執行自訂動作。

protected public:
 virtual IAsyncResult ^ OnBeginWorkflowCompleted(System::Activities::ActivityInstanceState completionState, System::Collections::Generic::IDictionary<System::String ^, System::Object ^> ^ workflowOutputs, Exception ^ terminationException, TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);
protected internal virtual IAsyncResult OnBeginWorkflowCompleted(System.Activities.ActivityInstanceState completionState, System.Collections.Generic.IDictionary<string,object> workflowOutputs, Exception terminationException, TimeSpan timeout, AsyncCallback callback, object state);
abstract member OnBeginWorkflowCompleted : System.Activities.ActivityInstanceState * System.Collections.Generic.IDictionary<string, obj> * Exception * TimeSpan * AsyncCallback * obj -> IAsyncResult
override this.OnBeginWorkflowCompleted : System.Activities.ActivityInstanceState * System.Collections.Generic.IDictionary<string, obj> * Exception * TimeSpan * AsyncCallback * obj -> IAsyncResult
Protected Friend Overridable Function OnBeginWorkflowCompleted (completionState As ActivityInstanceState, workflowOutputs As IDictionary(Of String, Object), terminationException As Exception, timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResult

參數

completionState
ActivityInstanceState

工作流程實例的狀態。

workflowOutputs
IDictionary<String,Object>

一組包含工作流程實例產生輸出的鍵值對。

terminationException
Exception

如果存在，則是導致工作流程終止的錯誤。

timeout
TimeSpan

非同步操作必須完成的時間區間。

callback
AsyncCallback

應用程式中非同步操作完成時，控制權會返回的位置。

state
Object

使用者自訂狀態。

傳回

IAsyncResult

非同步操作的狀態。

範例

以下範例說明如何實作此 OnBeginWorkflowCompleted 方法。

protected override IAsyncResult OnBeginWorkflowCompleted(ActivityInstanceState completionState, IDictionary<string, object> workflowOutputs,
    Exception faultedReason, TimeSpan timeout, AsyncCallback callback, object state)
{
    if (completionState == ActivityInstanceState.Faulted)
    {
        Console.WriteLine("InstanceId :" + InstanceId + " OnBeginWorkflowTerminated");
    }
    else if (completionState == ActivityInstanceState.Canceled)
    {
        Console.WriteLine("InstanceId :" + InstanceId + " OnBeginWorkflowCanceled");
    }
    else
    {
        Console.WriteLine("InstanceId :" + InstanceId + " OnBeginWorkflowCompleted");
        WorkflowHostingResponseContext responseContext = UserState as WorkflowHostingResponseContext;
        if (responseContext != null)
        {
            foreach (object value in workflowOutputs.Values)
            {
                responseContext.SendResponse(value, null);
                break;
            }
        }
    }
    return base.OnBeginWorkflowCompleted(completionState, workflowOutputs, faultedReason, timeout, callback, state);
}
