EventInstance(Int64, Int32)

Sumber:

EventData.cs

Menginisialisasi instans EventInstance baru kelas menggunakan pengidentifikasi sumber daya yang ditentukan untuk pesan yang dilokalkan dan teks kategori entri peristiwa.

public:
 EventInstance(long instanceId, int categoryId);

public EventInstance (long instanceId, int categoryId);

new System.Diagnostics.EventInstance : int64 * int -> System.Diagnostics.EventInstance

Public Sub New (instanceId As Long, categoryId As Integer)

Parameter

instanceId

Int64

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

categoryId

Int32

Pengidentifikasi sumber daya yang sesuai dengan string yang ditentukan dalam file sumber daya kategori sumber peristiwa, atau nol untuk menentukan tidak ada kategori untuk peristiwa tersebut.

Pengecualian

ArgumentOutOfRangeException

Parameter instanceId adalah nilai negatif atau nilai yang lebih besar dari UInt32.MaxValue.

-atau-

Parameter categoryId adalah nilai negatif atau nilai yang lebih besar dari UInt16.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.

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

Keterangan

Untuk menulis entri informasi ke log peristiwa, inisialisasi EventInstance dan teruskan ke WriteEvent metode . instanceId Atur ke pengidentifikasi sumber daya pesan peristiwa di properti terkait MessageResourceFile untuk sumbernya. Atur ke categoryId nilai kategori numerik, atau pengidentifikasi sumber daya kategori peristiwa di CategoryResourceFile properti untuk sumber; atur categoryId ke nol untuk tidak ada kategori peristiwa. Properti EntryType untuk instans baru diatur ke Information secara default.

Pemantau Peristiwa menggunakan pengidentifikasi sumber daya untuk menampilkan string yang sesuai dari file sumber daya yang dilokalkan untuk sumber. Anda harus mendaftarkan sumber dengan file sumber daya yang sesuai sebelum dapat menulis peristiwa menggunakan pengidentifikasi sumber daya.
