WorkflowRuntime.WorkflowIdled Evento
Definição
Ocorre quando uma instância de fluxo de trabalho entra no estado ocioso.Occurs when a workflow instance enters the idle state.
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)
Tipo de evento
Exemplos
O exemplo de código a seguir demonstra como usar a WorkflowRuntime funcionalidade de um host de fluxo de trabalho.The following code example demonstrates how to use WorkflowRuntime functionality from a workflow host. O código associa o a WorkflowIdled um manipulador de eventos, um método chamado OnWorkflowIdled .The code associates the WorkflowIdled with an event handler, a method named OnWorkflowIdled.
Este exemplo de código faz parte do exemplo de cancelamento de um fluxo de trabalho .This code example is part of the Canceling a Workflow sample.
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 gera o WorkflowIdled evento quando a instância do fluxo de trabalho entra em um estado ocioso; por exemplo, quando o fluxo de trabalho está aguardando a conclusão de uma DelayActivity atividade.The workflow run-time engine raises the WorkflowIdled event when the workflow instance enters an idle state; for example, when the workflow is waiting for a DelayActivity activity to complete.
Para esse evento, o remetente contém o WorkflowRuntime e WorkflowEventArgs contém o WorkflowInstance associado ao evento.For this event, the sender contains the WorkflowRuntime and WorkflowEventArgs contains the WorkflowInstance associated with the event.
