TrackingProfile.ActivityTrackPoints Properti

Definisi

Ruang nama:

System.Workflow.Runtime.Tracking

Rakitan:

System.Workflow.Runtime.dll

Mendapatkan kumpulan titik trek aktivitas yang digunakan oleh infrastruktur pelacakan runtime untuk memfilter peristiwa status aktivitas.

public:
 property System::Workflow::Runtime::Tracking::ActivityTrackPointCollection ^ ActivityTrackPoints { System::Workflow::Runtime::Tracking::ActivityTrackPointCollection ^ get(); };

public System.Workflow.Runtime.Tracking.ActivityTrackPointCollection ActivityTrackPoints { get; }

member this.ActivityTrackPoints : System.Workflow.Runtime.Tracking.ActivityTrackPointCollection

Public ReadOnly Property ActivityTrackPoints As ActivityTrackPointCollection

Nilai Properti

ActivityTrackPointCollection

ActivityTrackPointCollection yang menentukan titik dalam instans alur kerja tempat infrastruktur pelacakan runtime harus mengirim ActivityTrackingRecord ke layanan pelacakan.

Contoh

Contoh kode berikut menunjukkan bagaimana Anda dapat membuat TrackingProfile menggunakan TrackingProfile konstruktor dan menggunakan properti objek untuk membantu melacak eksekusi alur kerja. Contoh kode menggunakan ActivityTrackPointsproperti , Version, dan WorkflowTrackPoints .

Contoh kode ini adalah bagian dari Kueri menggunakan sampel SQLTrackingService SDK dari file Program.cs. Untuk informasi selengkapnya, lihat Kueri Menggunakan SQLTrackingService.

private static void CreateAndInsertTrackingProfile()
{
    TrackingProfile profile = new TrackingProfile();

    ActivityTrackingLocation activityLocation = new ActivityTrackingLocation(typeof(Activity));

    IEnumerable<ActivityExecutionStatus> statuses = Enum.GetValues(typeof(ActivityExecutionStatus)) as IEnumerable<ActivityExecutionStatus>;
    foreach (ActivityExecutionStatus status in statuses)
    {
        activityLocation.ExecutionStatusEvents.Add(status);
    }

    activityTrack.MatchingLocations.Add(activityLocation);
    profile.ActivityTrackPoints.Add(activityTrack);
    profile.Version = version;

    WorkflowTrackPoint workflowTrack = new WorkflowTrackPoint();
    WorkflowTrackingLocation workflowLocation = new WorkflowTrackingLocation();
    IEnumerable<TrackingWorkflowEvent> eventStatuses = Enum.GetValues(typeof(TrackingWorkflowEvent)) as IEnumerable<TrackingWorkflowEvent>;

    StringWriter writer = new StringWriter(new StringBuilder(), CultureInfo.InvariantCulture);
    serializer.Serialize(writer, profile);

Keterangan

Instans alur kerja memancarkan peristiwa status aktivitas ke infrastruktur pelacakan runtime setiap kali ActivityExecutionStatus instans aktivitas berubah. Infrastruktur pelacakan runtime menggunakan ActivityTrackPoints properti untuk memfilter peristiwa status aktivitas ini untuk menentukan kapan harus mengirim ActivityTrackingRecord ke layanan pelacakan. Anda dapat menambahkan ActivityTrackPoint ke ActivityTrackPoints properti untuk menentukan titik yang menarik dalam jalur eksekusi potensial instans alur kerja tempat Anda ingin infrastruktur runtime mengirim ActivityTrackingRecord.

ActivityTrackPoint Tidak benar-benar menentukan titik fisik dalam instans alur kerja, tetapi sebaliknya menentukan sekumpulan parameter kecocokan yang dapat digunakan oleh infrastruktur pelacakan runtime agar sesuai dengan peristiwa status aktivitas yang harus dikirim ActivityTrackingRecord. Oleh karena itu, hal yang sama ActivityTrackPoint dapat dicocokkan berkali-kali selama masa pakai instans alur kerja. Juga ActivityTrackPoint dapat menentukan data yang akan diekstrak dari instans alur kerja dan dikembalikan di ActivityTrackingRecord.
