WorkflowRuntime.WorkflowCompleted Evento

Definição

Namespace:

System.Workflow.Runtime

Assembly:

System.Workflow.Runtime.dll

Ocorre quando uma instância de fluxo de trabalho foi concluída.

public:
 event EventHandler<System::Workflow::Runtime::WorkflowCompletedEventArgs ^> ^ WorkflowCompleted;

public event EventHandler<System.Workflow.Runtime.WorkflowCompletedEventArgs> WorkflowCompleted;

member this.WorkflowCompleted : EventHandler<System.Workflow.Runtime.WorkflowCompletedEventArgs> 

Public Event WorkflowCompleted As EventHandler(Of WorkflowCompletedEventArgs) 

Tipo de evento

EventHandler<WorkflowCompletedEventArgs>

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 WorkflowCompleted um manipulador de eventos, um método chamado OnWorkflowCompleted.

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

WorkflowCompleted é gerado após a conclusão da instância de fluxo de trabalho, mas antes que a instância seja invalidada na memória.

Para o WorkflowPersisted evento, o remetente contém o WorkflowRuntime e WorkflowCompletedEventArgs contém o WorkflowInstance e seus parâmetros de saída.
