WorkflowRuntime.WorkflowIdled Événement

Définition

Se produit lorsqu'une instance de workflow entre en état d'inactivité.

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 Custom Event WorkflowIdled As EventHandler(Of WorkflowEventArgs) 
Public Event WorkflowIdled As EventHandler(Of WorkflowEventArgs) 

Type d'événement

Exemples

L'exemple de code suivant montre comment utiliser les fonctionnalités WorkflowRuntime d'un hôte de workflow. Le code associe l'événement WorkflowIdled à un gestionnaire d'événements, méthode qui est nommée OnWorkflowIdled.

Cet exemple de code fait partie de l’exemple d’annulation d’un flux de travail .

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

Remarques

Le moteur d'exécution de workflow déclenche l'événement WorkflowIdled lorsque l'instance de workflow entre dans l'état d'inactivité ; par exemple, lorsque le workflow attend qu'une activité DelayActivity se termine.

Pour cet événement, l'expéditeur contient l'objet WorkflowRuntime et l'objet WorkflowEventArgs contient l'objet WorkflowInstance associé à l'événement.

Pour plus d’informations sur la gestion des événements, consultez Gestion et déclenchement d’événements.
