WorkflowRuntime.WorkflowLoaded WorkflowRuntime.WorkflowLoaded WorkflowRuntime.WorkflowLoaded WorkflowRuntime.WorkflowLoaded Event

정의

워크플로 인스턴스가 메모리에 로드될 때 발생합니다.Occurs when the workflow instance is loaded into memory.

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) 

예제

다음 코드 예제에서는 워크플로 호스트에서 WorkflowRuntime 기능을 사용하는 방법을 보여 줍니다.The following code example demonstrates how to use WorkflowRuntime functionality from a workflow host. 이 코드에서는 WorkflowLoaded를 이벤트 처리기인 OnWorkflowLoad 메서드에 연결합니다.The code associates the WorkflowLoaded with an event handler, a method named OnWorkflowLoad.

일부인이 코드 예제는 Custom Persistence Service 샘플입니다.This code example is part of the Custom Persistence Service sample.

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 occurs after the persistence service has restored the workflow instance, but before the workflow run-time engine begins to execute any activities.

WorkflowLoaded 이벤트의 경우 발신자는 WorkflowRuntime을 포함하고 WorkflowEventArgs는 이벤트와 연결된 WorkflowInstance를 포함합니다.For the WorkflowLoaded event, the sender contains the WorkflowRuntime and WorkflowEventArgs contains the WorkflowInstance associated with the event.

이벤트를 처리 하는 방법에 대 한 자세한 내용은 이벤트 처리 및 발생을 참조 하세요.For more information about handling events, see Handling and raising events.
