WorkflowRuntime.WorkflowLoaded 이벤트

정의

네임스페이스:

System.Workflow.Runtime

어셈블리:

System.Workflow.Runtime.dll

워크플로 인스턴스가 메모리에 로드될 때 발생합니다.

public:
 event EventHandler<System::Workflow::Runtime::WorkflowEventArgs ^> ^ WorkflowLoaded;

public event EventHandler<System.Workflow.Runtime.WorkflowEventArgs> WorkflowLoaded;

member this.WorkflowLoaded : EventHandler<System.Workflow.Runtime.WorkflowEventArgs> 

Public Event WorkflowLoaded As EventHandler(Of WorkflowEventArgs) 

이벤트 유형

EventHandler<WorkflowEventArgs>

예제

다음 코드 예제에서는 워크플로 호스트에서 WorkflowRuntime 기능을 사용하는 방법을 보여 줍니다. 이 코드에서는 WorkflowLoaded를 이벤트 처리기인 OnWorkflowLoad 메서드에 연결합니다.

이 코드 예제는 사용자 지정 지속성 서비스 샘플의 일부입니다.

static void Main()
{
    using (WorkflowRuntime workflowRuntime = new WorkflowRuntime())
    {
        try
        {
            // engine will unload workflow instance when it is idle
            workflowRuntime.AddService(new FilePersistenceService(true));

            workflowRuntime.WorkflowCreated += OnWorkflowCreated;
            workflowRuntime.WorkflowCompleted += OnWorkflowCompleted;
            workflowRuntime.WorkflowIdled += OnWorkflowIdle;
            workflowRuntime.WorkflowUnloaded += OnWorkflowUnload;
            workflowRuntime.WorkflowLoaded += OnWorkflowLoad;
            workflowRuntime.WorkflowTerminated += OnWorkflowTerminated;
            workflowRuntime.ServicesExceptionNotHandled += OnExceptionNotHandled;

            workflowRuntime.CreateWorkflow(typeof(PersistenceServiceWorkflow)).Start();

            waitHandle.WaitOne();
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception \n\t Source: {0} \n\t Message: {1}", e.Source, e.Message);
        }
        finally
        {
            workflowRuntime.StopRuntime();
            Console.WriteLine("Workflow runtime stopped, program exiting... \n");
        }
    }
}

Shared Sub Main()

    Using currentWorkflowRuntime As New WorkflowRuntime()
        Try

            ' engine will unload workflow instance when it is idle
            currentWorkflowRuntime.AddService(New FilePersistenceService(True))

            AddHandler currentWorkflowRuntime.WorkflowCreated, AddressOf OnWorkflowCreated
            AddHandler currentWorkflowRuntime.WorkflowCompleted, AddressOf OnWorkflowCompleted
            AddHandler currentWorkflowRuntime.WorkflowIdled, AddressOf OnWorkflowIdled
            AddHandler currentWorkflowRuntime.WorkflowUnloaded, AddressOf OnWorkflowUnloaded
            AddHandler currentWorkflowRuntime.WorkflowLoaded, AddressOf OnWorkflowLoaded
            AddHandler currentWorkflowRuntime.WorkflowTerminated, AddressOf OnWorkflowTerminated
            AddHandler currentWorkflowRuntime.ServicesExceptionNotHandled, AddressOf OnExceptionNotHandled

            currentWorkflowRuntime.CreateWorkflow(GetType(PersistenceServiceWorkflow)).Start()

            waitHandle.WaitOne()

        Catch e As Exception
            Console.WriteLine("Exception \n\t Source: 0} \n\t Message: 1}", e.Source, e.Message)
        Finally
            currentWorkflowRuntime.StopRuntime()
            Console.WriteLine("Workflow runtime stopped, program exiting... \n")
        End Try
    End Using
End Sub

설명

WorkflowLoaded는 지속성 서비스가 워크플로 인스턴스를 복원한 후, 워크플로 런타임 엔진이 활동 실행을 시작하기 전에 발생합니다.

WorkflowLoaded 이벤트의 경우 발신자는 WorkflowRuntime을 포함하고 WorkflowEventArgs는 이벤트와 연결된 WorkflowInstance를 포함합니다.
