WorkflowCreationContext.OnBeginWorkflowCompleted 方法

定义

命名空间:

System.ServiceModel.Activities

程序集:

System.ServiceModel.Activities.dll

开始异步操作以执行工作流实例完成通知。 当与此 WorkflowCreationContext 关联的工作流实例完成时调用此方法。 派生类可覆盖此操作以针对工作流实例的完成事件执行自定义操作。

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

参数

completionState

ActivityInstanceState

工作流实例的状态。

workflowOutputs

IDictionary<String,Object>

包含工作流实例生成的输出的键/值对的集合。

terminationException

Exception

导致工作流终止的错误（如果存在）。

timeout

TimeSpan

必须在此时间内完成异步操作的时间间隔。

callback

AsyncCallback

异步操作完成时将控制权返回到的应用程序中的位置。

state

Object

用户定义的状态。

返回

IAsyncResult

异步操作的状态。

示例

下面的示例演示如何实现 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);
}
