Mendapatkan atau mengatur pengidentifikasi sumber daya yang menunjuk teks pesan entri peristiwa.
public:
property long InstanceId { long get(); void set(long value); };
public long InstanceId { get; set; }
member this.InstanceId : int64 with get, set
Public Property InstanceId As Long
Nilai Properti
Pengidentifikasi sumber daya yang sesuai dengan string yang ditentukan dalam file sumber daya pesan dari sumber peristiwa.
Pengecualian
Properti diatur ke nilai negatif atau ke nilai yang lebih besar dari UInt32.MaxValue.
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.
// Ensure that the source has already been registered using
// EventLogInstaller or EventLog.CreateEventSource.
String^ sourceName = "SampleApplicationSource";
if ( EventLog::SourceExists( sourceName ) )
{
// Define an informational event with no category.
// 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
// for the registered source. Set the event type to Warning.
myEvent->CategoryId = RefreshCategoryMsgId;
myEvent->EntryType = EventLogEntryType::Warning;
myEvent->InstanceId = ServerConnectionDownMsgId;
// Write the event to the event log using the registered source.
// Insert the machine name into the event message text.
array<String^>^ss = {Environment::MachineName};
EventLog::WriteEvent( sourceName, myEvent, ss );
}

{
Console::WriteLine( "Warning - event source {0} not registered", sourceName );

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

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.
