Penting
Beberapa informasi terkait produk prarilis yang dapat diubah secara signifikan sebelum dirilis. Microsoft tidak memberikan jaminan, tersirat maupun tersurat, sehubungan dengan informasi yang diberikan di sini.
Terjadi saat instans alur kerja memasuki status menganggur.

Jenis Acara
Contoh
Contoh kode berikut menunjukkan cara menggunakan WorkflowRuntime fungsionalitas dari host alur kerja. Kode mengaitkan WorkflowIdled dengan penanganan aktivitas, metode bernama OnWorkflowIdled
.
Contoh kode ini adalah bagian dari sampel Membatalkan Alur Kerja .
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
Keterangan
Mesin run-time alur kerja menaikkan peristiwa saat instans WorkflowIdled alur kerja memasuki status menganggur; misalnya, saat alur kerja menunggu DelayActivity aktivitas selesai.
Untuk kejadian ini, pengirim berisi WorkflowRuntime dan WorkflowEventArgs berisi yang WorkflowInstance terkait dengan peristiwa.
Untuk informasi selengkapnya tentang menangani peristiwa, lihat Menangani dan menaikkan peristiwa.
