WorkflowRuntime.WorkflowCreated Kejadian

Definisi

Ruang nama:

System.Workflow.Runtime

Rakitan:

System.Workflow.Runtime.dll

Terjadi saat instans alur kerja dibuat.

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

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

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

Public Event WorkflowCreated As EventHandler(Of WorkflowEventArgs) 

Jenis Acara

EventHandler<WorkflowEventArgs>

Contoh

Contoh kode berikut menunjukkan cara menggunakan WorkflowRuntime fungsionalitas dari host alur kerja. Kode mengaitkan WorkflowCreated dengan penanganan aktivitas, metode bernama OnWorkflowCreated.

Contoh kode ini adalah bagian dari Sampel Layanan Persistensi Kustom.

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

Keterangan

Mesin run-time alur kerja meningkatkan peristiwa setelah instans alur kerja benar-benar dibangun tetapi sebelum aktivitas diproses WorkflowCreated . Untuk kejadian ini, pengirim berisi WorkflowRuntime dan WorkflowEventArgs berisi yang WorkflowInstance terkait dengan peristiwa.

Untuk informasi selengkapnya tentang menangani peristiwa, lihat Menangani dan menaikkan peristiwa.
