The following example starts an instance of Notepad. It then retrieves the physical memory usage of the associated process at 2 second intervals for a maximum of 10 seconds. The example detects whether the process exits before 10 seconds have elapsed. The example closes the process if it is still running after 10 seconds.


using System;
using System.Diagnostics;
using System.Threading;

namespace Process_Sample
{
   class MyProcessClass
   {
      public static void Main()
      {
         try
         {
            Process myProcess;
            myProcess = Process.Start("Notepad.exe");
            // Display physical memory usage 5 times at intervals of 2 seconds.
            for (int i = 0;i < 5; i++)
            {
               if (!myProcess.HasExited)
               {
                   // Discard cached information about the process.
                   myProcess.Refresh();
                   // Print working set to console.
                   Console.WriteLine("Physical Memory Usage: " 
                                        + myProcess.WorkingSet.ToString());
                   // Wait 2 seconds.
                   Thread.Sleep(2000);
               }
               else {
                   break;
               } 
            }

            // Close process by sending a close message to its main window.
            myProcess.CloseMainWindow();
            // Free resources associated with process.
            myProcess.Close();

         }
         catch(Exception e)
         {
            Console.WriteLine("The following exception was raised: ");
            Console.WriteLine(e.Message);
         }
      }
   }
