Contoh

Untuk menggunakan contoh berikut, Anda harus terlebih dahulu memulai setidaknya satu instans Notepad di komputer jarak jauh. Contoh meminta nama komputer jarak jauh tempat Notepad berjalan, lalu menampilkan properti masing-masing ProcessName, Id, dan MachineName untuk setiap instans.

using System;
using System.Diagnostics;

class GetProcessesByNameClass
{
    public static void Main(string[] args)
    {
        Console.WriteLine("Create notepad processes on remote computer");
        Console.Write("Enter remote computer name : ");
        string remoteMachineName = Console.ReadLine();

        if (remoteMachineName == null)
        {
            // Prepend a new line to prevent it from being on the same line as the prompt.
            Console.WriteLine(Environment.NewLine + "You have to enter a remote computer name.");
            return;
        }

        try
        {
            // Get all notepad processess into Process array.
            Process[] myProcesses = Process.GetProcessesByName("notepad", remoteMachineName);

            if (myProcesses.Length == 0)
                Console.WriteLine("Could not find notepad processes on remote computer.");

Keterangan

Anda dapat melihat data statistik dan informasi proses untuk proses yang berjalan di komputer jarak jauh tetapi Anda tidak dapat memanggil Start, CloseMainWindow, atau Kill di komputer jarak jauh.

Catatan

Ketika proses terkait dijalankan pada komputer lokal, properti ini mengembalikan titik (".") untuk nama komputer. Anda harus menggunakan Environment.MachineName properti untuk mendapatkan nama komputer yang benar.
