TrackingProfile.Version Properti

Definisi

Ruang nama:

System.Workflow.Runtime.Tracking

Rakitan:

System.Workflow.Runtime.dll

Mendapatkan atau mengatur versi profil pelacakan.

public:
 property Version ^ Version { Version ^ get(); void set(Version ^ value); };

public Version Version { get; set; }

member this.Version : Version with get, set

Public Property Version As Version

Nilai Properti

Version

Version dari TrackingProfile.

Contoh

Contoh kode berikut menunjukkan bagaimana Anda dapat membuat TrackingProfile menggunakan TrackingProfile konstruktor dan menggunakan properti objek untuk membantu melacak eksekusi alur kerja. Kode contoh 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.

Keterangan

Karena semantik penembolokan profil di mesin runtime alur kerja, jika Anda mengubah konten yang TrackingProfile harus Anda perbarui Version. Jika tidak, pembaruan TrackingProfile Anda mungkin tidak dimuat oleh mesin runtime alur kerja, meskipun dikembalikan oleh panggilan ke TrackingService.TryReloadProfile, atau dikirim dalam ProfileUpdatedEventArgs peristiwa yang ProfileUpdated terkait. Oleh karena itu, untuk memastikan bahwa pembaruan TrackingProfile dimuat oleh mesin runtime alur kerja, Anda harus mengubah Version untuk TrackingProfile. Anda kemudian dapat secara eksplisit memanggil WorkflowInstance.ReloadTrackingProfiles instans alur kerja yang sesuai, atau, tergantung pada implementasi Anda, Anda dapat mengandalkan layanan pelacakan untuk menginformasikan mesin runtime alur kerja tentang perubahan tersebut. Untuk informasi selengkapnya, lihat TrackingService.
