WorkflowRuntime.WorkflowIdled Evento

Definición

Espacio de nombres:

System.Workflow.Runtime

Ensamblado:

System.Workflow.Runtime.dll

Se produce cuando una instancia de flujo de trabajo entra en el estado inactivo.

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) 

Tipo de evento

EventHandler<WorkflowEventArgs>

Ejemplos

El ejemplo de código siguiente muestra cómo se puede utilizar la funcionalidad WorkflowRuntime desde un host del flujo de trabajo. El código asocia WorkflowIdled a un controlador de eventos, un método denominado OnWorkflowIdled.

Este ejemplo de código forma parte del ejemplo Cancelar un flujo de trabajo .

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

Comentarios

El motor en tiempo de ejecución de flujo de trabajo genera el evento WorkflowIdled cuando la instancia de flujo de trabajo entra en un estado inactivo; por ejemplo, cuando el flujo de trabajo está esperando a que una actividad DelayActivity se complete.

Para este evento, el remitente contendrá WorkflowRuntime y WorkflowEventArgs contendrá el WorkflowInstance asociado al evento.
