Keterangan

EventLogEntryCollection Gunakan kelas saat membaca entri yang EventLog terkait dengan instans. Properti Entries kelas EventLog adalah kumpulan semua entri dalam log peristiwa.

Karena entri baru ditambahkan ke daftar yang ada, menelusuri koleksi memungkinkan Anda mengakses entri yang dibuat setelah Anda awalnya membuat EventLogEntryCollection. Namun, setelah Anda melihat seluruh daftar, daftar tersebut tidak diperbarui dengan entri baru.

Properti

Nama	Deskripsi
Count	Mendapatkan jumlah entri dalam log peristiwa (yaitu, jumlah elemen dalam EventLogEntry koleksi).
Item[Int32]	Mendapatkan entri dalam log peristiwa, berdasarkan indeks yang dimulai pada 0 (nol).

Metode

Nama	Deskripsi
CopyTo(EventLogEntry[], Int32)	Menyalin elemen EventLogEntryCollection ke array EventLogEntry instans, dimulai pada indeks array tertentu.
GetEnumerator()	Mendukung iterasi sederhana atas EventLogEntryCollection objek.

Implementasi Antarmuka Eksplisit

Nama	Deskripsi
ICollection.CopyTo(Array, Int32)	Menyalin elemen koleksi ke Array, dimulai pada indeks tertentu Array .
ICollection.IsSynchronized	Mendapatkan nilai yang menunjukkan apakah akses ke EventLogEntryCollection disinkronkan (aman utas).
ICollection.SyncRoot	Mendapatkan objek yang dapat digunakan untuk menyinkronkan akses ke EventLogEntryCollection objek.
