Keterangan

Gunakan metode ini untuk membuat array komponen baru Process dan mengaitkannya dengan semua sumber daya proses di komputer lokal. Sumber daya proses harus sudah ada di komputer lokal, karena GetProcesses tidak membuat sumber daya sistem melainkan mengaitkan sumber daya dengan komponen yang dihasilkan Process aplikasi. Karena sistem operasi itu sendiri menjalankan proses latar belakang, array ini tidak pernah kosong.

Jika Anda tidak ingin mengambil semua proses yang berjalan di komputer, Anda dapat membatasi jumlahnya dengan menggunakan GetProcessById metode atau GetProcessesByName . GetProcessByIdProcess membuat komponen yang terkait dengan proses yang diidentifikasi pada sistem oleh pengidentifikasi proses yang Anda berikan ke metode . GetProcessesByName membuat array Process komponen yang sumber daya proses terkaitnya berbagi file yang dapat dieksekusi yang Anda berikan ke metode .

Catatan

Beberapa layanan Windows dapat dimuat dalam instans yang sama dari proses Host Layanan (svchost.exe). GetProcesses tidak mengidentifikasi layanan individu tersebut; untuk itu, lihat GetServices.
