[C#] "Access is denied" pour récupérer le temps processeur

Bonjour,

J'essai de récupérer le temps processeur occupé par chacun des process tournant sur mon PC. J'arrive à récupérer le nom du process, son ID, la taille mémoire utilisée mais j'ai systématiquement une Win32Exception : access is denied quand je veux récupérer le temps processor.

Code:

---

1 2 3 4 5 6 7 8 9

processListView.Items.Clear(); foreach (Process process in Process.GetProcesses()) { ListViewItem currentItem = new ListViewItem(process.Id.ToString(), 0); currentItem.SubItems.Add(process.ProcessName); currentItem.SubItems.Add(process.TotalProcessorTime.ToString()); currentItem.SubItems.Add(""+(process.WorkingSet64/1024)+" K"); processListView.Items.Add(currentItem); }

---

qqun aurait il une idée ?

merci d'avance...

Code:

---

1 2 3 4 5 6

foreach (Process process in Process.GetProcesses()) { if (process.Id != 0) System.Diagnostics.Debug.WriteLine(process.TotalProcessorTime.ToString()); }

Il faut que tu évite d'aller chercher le process idle (processname = idle & processId = 0). C'est pour ca qu'il te lance une exception
