Obtenir l'utilisation actuelle du processeur, de la RAM et du lecteur de disque en C#

Question

Comment obtenir l'utilisation du processeur, de la RAM et du lecteur de disque du système en code C#?

Answer 1

Veuillez rechercher SO; il y a plusieurs questions similiar:

• How to get the CPU Usage C#

• C#: List all processes and their current memory & CPU consumption?

• How do I retrieve disk information in C#?

Voici une solution qui sera l'utilisation du disque de sortie, le pour cent disque total utilisé à l'heure à laquelle Timer99 est interrogé:

using System; 
using System.Diagnostics; 
using System.Windows; 

namespace diskpercent 
{ 
    public partial class MainWindow : Window 
    { 
     DispatcherTimer Timer99 = new DispatcherTimer(); 
     public MainWindow() 
     { 
      InitializeComponent(); 
      Timer99.Tick += Timer99_Tick; // don't freeze the ui 
      Timer99.Interval = new TimeSpan(0, 0, 0, 0, 1024); 
      Timer99.IsEnabled = true; 
     } 
     public PerformanceCounter myCounter = 
      new PerformanceCounter("PhysicalDisk", "% Disk Time", "_Total"); 
     public Int32 j = 0; 
     public void Timer99_Tick(System.Object sender, System.EventArgs e) 

     { 
       //Console.Clear(); 
      j = Convert.ToInt32(myCounter.NextValue());  
       //Console.WriteLine(j); 
      textblock1.Text = j.ToString(); 
     } 
    } 
} 

et voici une liste des compteurs de performance communs:

PerformanceCounter("Processor", "% Processor Time", "_Total"); 
PerformanceCounter("Processor", "% Privileged Time", "_Total"); 
PerformanceCounter("Processor", "% Interrupt Time", "_Total"); 
PerformanceCounter("Processor", "% DPC Time", "_Total"); 
PerformanceCounter("Memory", "Available MBytes", null); 
PerformanceCounter("Memory", "Committed Bytes", null); 
PerformanceCounter("Memory", "Commit Limit", null); 
PerformanceCounter("Memory", "% Committed Bytes In Use", null); 
PerformanceCounter("Memory", "Pool Paged Bytes", null); 
PerformanceCounter("Memory", "Pool Nonpaged Bytes", null); 
PerformanceCounter("Memory", "Cache Bytes", null); 
PerformanceCounter("Paging File", "% Usage", "_Total"); 
PerformanceCounter("PhysicalDisk", "Avg. Disk Queue Length", "_Total"); 
PerformanceCounter("PhysicalDisk", "Disk Read Bytes/sec", "_Total"); 
PerformanceCounter("PhysicalDisk", "Disk Write Bytes/sec", "_Total"); 
PerformanceCounter("PhysicalDisk", "Avg. Disk sec/Read", "_Total"); 
PerformanceCounter("PhysicalDisk", "Avg. Disk sec/Write", "_Total"); 
PerformanceCounter("PhysicalDisk", "% Disk Time", "_Total"); 
PerformanceCounter("Process", "Handle Count", "_Total"); 
PerformanceCounter("Process", "Thread Count", "_Total"); 
PerformanceCounter("System", "Context Switches/sec", null); 
PerformanceCounter("System", "System Calls/sec", null); 
PerformanceCounter("System", "Processor Queue Length", null);
