EventSourceCreationData(String, String) Konstruktor

Definisi

Ruang nama:

System.Diagnostics

Rakitan:

System.Diagnostics.EventLog.dll

Paket:

System.Diagnostics.EventLog v8.0.0

Sumber:

EventSourceCreationData.cs

Menginisialisasi instans EventSourceCreationData baru kelas dengan sumber peristiwa dan nama log peristiwa tertentu.

public:
 EventSourceCreationData(System::String ^ source, System::String ^ logName);

public EventSourceCreationData (string source, string logName);

new System.Diagnostics.EventSourceCreationData : string * string -> System.Diagnostics.EventSourceCreationData

Public Sub New (source As String, logName As String)

Parameter

source

String

Nama untuk mendaftar dengan log peristiwa sebagai sumber entri.

logName

String

Nama log tempat entri dari sumber ditulis.

Contoh

Contoh kode berikut menentukan apakah sumber peristiwa bernama SampleApplicationSource terdaftar di komputer lokal. Jika sumber peristiwa tidak ada, contoh mengatur file sumber daya pesan untuk sumber dan membuat sumber peristiwa baru. Terakhir, contoh kode mengatur nama tampilan yang dilokalkan untuk log peristiwa, menggunakan nilai pengidentifikasi sumber daya di DisplayNameMsgId dan jalur file sumber daya di messageFile.

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 ke log peristiwa, Anda harus terlebih dahulu membuat sumber kejadian untuk log peristiwa. Untuk mendaftarkan sumber baru, inisialisasi EventSourceCreationData instans, konfigurasikan properti instans untuk aplikasi Anda, dan panggil EventLog.CreateEventSource(EventSourceCreationData) metode . Setelah sumber terdaftar, Anda dapat menulis entri dari sumber menggunakan WriteEvent metode atau WriteEntry .

Anda dapat mendaftarkan sumber peristiwa dengan sumber daya yang dilokalkan untuk kategori peristiwa dan string pesan Anda. Aplikasi Anda dapat menulis entri log peristiwa menggunakan pengidentifikasi sumber daya, daripada menentukan string aktual. Pemantau Peristiwa menggunakan pengidentifikasi sumber daya untuk menemukan dan menampilkan string yang sesuai dari file sumber daya yang dilokalkan berdasarkan pengaturan bahasa saat ini. Anda dapat mendaftarkan file terpisah untuk kategori peristiwa, pesan, dan string penyisipan parameter, atau Anda dapat mendaftarkan file sumber daya yang sama untuk ketiga jenis string. CategoryCountGunakan properti , CategoryResourceFile, MessageResourceFile, dan ParameterResourceFile untuk mengonfigurasi sumber untuk menulis entri yang dilokalkan ke log peristiwa. Jika aplikasi Anda menulis nilai string langsung ke log peristiwa, Anda tidak perlu mengatur properti ini.

Sumber harus dikonfigurasi baik untuk menulis entri yang dilokalkan atau untuk menulis string langsung. Jika aplikasi Anda menulis entri menggunakan pengidentifikasi sumber daya dan nilai string, Anda harus mendaftarkan dua sumber terpisah. Misalnya, konfigurasikan satu sumber dengan file sumber daya, lalu gunakan sumber tersebut WriteEvent dalam metode untuk menulis entri menggunakan pengidentifikasi sumber daya ke log peristiwa. Kemudian buat sumber yang berbeda tanpa file sumber daya dan gunakan sumber tersebut WriteEntry dalam metode untuk menulis string langsung ke log peristiwa.

Tabel berikut ini memperlihatkan nilai properti awal untuk EventSourceCreationData.

Properti	Nilai Awal
Source	Parameter .source
LogName	Parameter .logName
MachineName	Komputer lokal (".").
CategoryCount	Nol
CategoryResourceFile	null (Nothing dalam Visual Basic).
MessageResourceFile	null (Nothing dalam Visual Basic).
ParameterResourceFile	null (Nothing dalam Visual Basic).
