WorkflowRuntime.WorkflowIdled Evento

Definição

Namespace:

System.Workflow.Runtime

Assembly:

System.Workflow.Runtime.dll

Ocorre quando uma instância de fluxo de trabalho entra no estado ocioso.

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>

Exemplos

O exemplo de código a seguir demonstra como usar WorkflowRuntime a funcionalidade de um host de fluxo de trabalho. O código associa o a WorkflowIdled um manipulador de eventos, um método chamado OnWorkflowIdled.

Este exemplo de código faz parte do exemplo cancelando um fluxo de trabalho .

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

Comentários

O mecanismo de tempo de execução do fluxo de trabalho aciona o WorkflowIdled evento quando a instância de fluxo de trabalho entra em um estado ocioso; por exemplo, quando o fluxo de trabalho está aguardando a conclusão de uma DelayActivity atividade.

Para esse evento, o remetente contém o WorkflowRuntime e WorkflowEventArgs contém o WorkflowInstance associado ao evento.
