Comment puis-je suivre avec précision le temps d'exécution des processus dans .NET ?

<code class="language-csharp">using System;
using System.Management;

public class ProcessMonitor
{
    public static void Main(string[] args)
    {
        // Watch for process start events
        using (ManagementEventWatcher startWatch = new ManagementEventWatcher(new WqlEventQuery("SELECT * FROM Win32_ProcessStartTrace")))
        {
            startWatch.EventArrived += StartWatch_EventArrived;
            startWatch.Start();

            // Watch for process stop events
            using (ManagementEventWatcher stopWatch = new ManagementEventWatcher(new WqlEventQuery("SELECT * FROM Win32_ProcessStopTrace")))
            {
                stopWatch.EventArrived += StopWatch_EventArrived;
                stopWatch.Start();

                Console.WriteLine("Monitoring process starts and stops. Press any key to exit.");
                Console.ReadKey();
            }
        }
    }

    private static void StopWatch_EventArrived(object sender, EventArrivedEventArgs e)
    {
        Console.WriteLine($"Process stopped: {e.NewEvent.Properties["ProcessName"].Value}");
    }

    private static void StartWatch_EventArrived(object sender, EventArrivedEventArgs e)
    {
        Console.WriteLine($"Process started: {e.NewEvent.Properties["ProcessName"].Value}");
    }
}</code>
