public long InstanceId { get; set; }

member this.InstanceId : int64 with get, set

Public Property InstanceId As Long

Nilai Properti

Int64

Pengidentifikasi sumber daya yang sesuai dengan string yang ditentukan dalam file sumber daya pesan dari sumber peristiwa.

Pengecualian

Contoh

Contoh kode berikut menulis entri peristiwa informasi, lalu menggunakan EventInstance kembali untuk menulis entri untuk peristiwa peringatan ke log peristiwa yang ada. Teks pesan peristiwa ditentukan menggunakan pengidentifikasi sumber daya dalam file sumber daya pesan. Contoh kode mengasumsikan bahwa file sumber daya pesan yang sesuai telah didaftarkan untuk sumbernya.

// EventLogInstaller or EventLog.CreateEventSource.

   // The message identifier corresponds to the message text in the
   // message resource file defined for the source.
   EventInstance ^ myEvent = gcnew EventInstance( UpdateCycleCompleteMsgId,0 );

   // Write the event to the event log using the registered source.
   EventLog::WriteEvent( sourceName, myEvent, 0 );

   // Reuse the event data instance for another event entry.
   // Set the entry category and message identifiers for
   // the appropriate resource identifiers in the resource files

Contoh kode menggunakan file teks pesan berikut, yang disertakan dalam pustaka sumber daya EventLogMsgs.dll. File teks pesan adalah sumber dari mana file sumber daya pesan dibuat. File teks pesan menentukan pengidentifikasi sumber daya dan teks untuk kategori, pesan peristiwa, dan string penyisipan parameter.

Keterangan

Properti InstanceId secara unik mengidentifikasi entri peristiwa untuk sumber peristiwa yang dikonfigurasi. Untuk peristiwa yang ditentukan dalam file sumber daya pesan, InstanceId sesuai dengan pengidentifikasi sumber daya yang dikompilasi dari bidang definisi pesan dalam file teks pesan. Aplikasi Anda dapat menulis entri log peristiwa yang dilokalkan dengan mengatur ke InstanceId pengidentifikasi sumber daya. Pemantau Peristiwa menggunakan InstanceId pengidentifikasi sumber daya untuk menemukan dan menampilkan string yang sesuai dari file sumber daya yang dilokalkan berdasarkan pengaturan bahasa saat ini. Anda harus mendaftarkan sumber dengan file sumber daya yang sesuai sebelum menulis peristiwa menggunakan pengidentifikasi sumber daya.

Untuk detail tentang menentukan pesan peristiwa dan membangun file sumber daya log peristiwa, lihat artikel Pengkompilasi Pesan di dokumentasi Platform SDK. Untuk detail tentang pengidentifikasi log peristiwa, lihat artikel Pengidentifikasi Peristiwa di dokumentasi Platform SDK.
