WorkflowRuntime.WorkflowIdled Kejadian

Definisi

Ruang nama:

System.Workflow.Runtime

Rakitan:

System.Workflow.Runtime.dll

Terjadi saat instans alur kerja memasuki status menganggur.

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

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

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

Public Event WorkflowIdled As EventHandler(Of WorkflowEventArgs) 

Jenis Acara

EventHandler<WorkflowEventArgs>

Contoh

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

Contoh kode ini adalah bagian dari sampel Membatalkan Alur Kerja .

static void Main()
{
    string connectionString = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;";

    using (WorkflowRuntime workflowRuntime = new WorkflowRuntime())
    {
        ExternalDataExchangeService dataService = new ExternalDataExchangeService();
        workflowRuntime.AddService(dataService);
        dataService.AddService(expenseService);

        workflowRuntime.AddService(new SqlWorkflowPersistenceService(connectionString));
        workflowRuntime.StartRuntime();

        workflowRuntime.WorkflowCompleted += OnWorkflowCompleted;
        workflowRuntime.WorkflowTerminated += OnWorkflowTerminated;
        workflowRuntime.WorkflowIdled += OnWorkflowIdled;
        workflowRuntime.WorkflowAborted += OnWorkflowAborted;

        Type type = typeof(SampleWorkflow1);
        WorkflowInstance workflowInstance = workflowRuntime.CreateWorkflow(type);
        workflowInstance.Start();

        waitHandle.WaitOne();

        workflowRuntime.StopRuntime();
    }
}

Shared Sub Main()
    Dim connectionString As String = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;"
    Using workflowRuntime As New WorkflowRuntime()
        Dim dataService As New ExternalDataExchangeService()
        workflowRuntime.AddService(dataService)
        dataService.AddService(expenseService)

        workflowRuntime.AddService(New SqlWorkflowPersistenceService(connectionString))


        AddHandler workflowRuntime.WorkflowCompleted, AddressOf OnWorkflowCompleted
        AddHandler workflowRuntime.WorkflowTerminated, AddressOf OnWorkflowTerminated
        AddHandler workflowRuntime.WorkflowIdled, AddressOf OnWorkflowIdled
        AddHandler workflowRuntime.WorkflowAborted, AddressOf OnWorkflowAborted


        Dim workflowInstance As WorkflowInstance
        workflowInstance = workflowRuntime.CreateWorkflow(GetType(SampleWorkflow))
        workflowInstance.Start()

        waitHandle.WaitOne()

        workflowRuntime.StopRuntime()
    End Using
End Sub

Keterangan

Mesin run-time alur kerja menaikkan peristiwa saat instans WorkflowIdled alur kerja memasuki status menganggur; misalnya, saat alur kerja menunggu DelayActivity aktivitas selesai.

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.
