有没有一种方法可以确定特定计算机上次运行进程的时间?
我可以使用以下命令来确定某个进程是否正在运行,但是如果此进程已停止,则该应用程序无法捕获该进程。
Process[] process = Process.GetProcessesByName(processName, serverName);
WMI提供了一种跟踪以Win32_ProcessTrace类开始和终止的进程的方法。最好的例子展示。启动一个新的控制台应用程序,在Project + Add Reference中,选择System.Management。粘贴以下代码:
using System; using System.Management; class Process { public static void Main() { ManagementEventWatcher startWatch = new ManagementEventWatcher( new WqlEventQuery("SELECT * FROM Win32_ProcessStartTrace")); startWatch.EventArrived += new EventArrivedEventHandler(startWatch_EventArrived); startWatch.Start(); ManagementEventWatcher stopWatch = new ManagementEventWatcher( new WqlEventQuery("SELECT * FROM Win32_ProcessStopTrace")); stopWatch.EventArrived += new EventArrivedEventHandler(stopWatch_EventArrived); stopWatch.Start(); Console.WriteLine("Press any key to exit"); while (!Console.KeyAvailable) System.Threading.Thread.Sleep(50); startWatch.Stop(); stopWatch.Stop(); } static void stopWatch_EventArrived(object sender, EventArrivedEventArgs e) { Console.WriteLine("Process stopped: {0}", e.NewEvent.Properties["ProcessName"].Value); } static void startWatch_EventArrived(object sender, EventArrivedEventArgs e) { Console.WriteLine("Process started: {0}", e.NewEvent.Properties["ProcessName"].Value); } }
编辑清单,使该程序提升运行。然后只需启动一些程序即可查看其工作情况。注意它不是特别快。
