Keterangan

Gunakan metode ini untuk membuat komponen baru Process dan mengaitkannya dengan sumber daya proses di komputer lokal. Sumber daya proses harus sudah ada di komputer, karena GetProcessById(Int32) tidak membuat sumber daya sistem, melainkan mengaitkan sumber daya dengan komponen yang dihasilkan Process aplikasi. Proses Id hanya dapat diambil untuk proses yang saat ini berjalan di komputer. Setelah proses berakhir, GetProcessById(Int32) melemparkan pengecualian jika Anda meneruskannya pengidentifikasi yang kedaluwarsa.

Pada komputer tertentu, pengidentifikasi proses bersifat unik. GetProcessById(Int32) mengembalikan satu proses paling banyak. Jika Anda ingin mendapatkan semua proses yang menjalankan aplikasi tertentu, gunakan GetProcessesByName(String). Jika ada beberapa proses di komputer yang menjalankan aplikasi yang ditentukan, GetProcessesByName(String) mengembalikan array yang berisi semua proses terkait. Anda dapat mengkueri setiap proses ini pada gilirannya untuk pengidentifikasinya. Pengidentifikasi proses dapat dilihat di Processes panel Windows Task Manager. Kolom PID menampilkan pengidentifikasi proses yang ditetapkan ke proses.

Parameternya processId adalah Int32 (bilangan bulat bertanda tangan 32-bit), meskipun Windows API yang mendasar DWORD menggunakan (bilangan bulat 32-bit yang tidak ditandatangani) untuk API serupa. Ini karena alasan historis.
