.NET 进程监视器 [英] .NET Process Monitor

问题描述

有没有办法确定特定机器上次运行进程的时间?

Is there a way to determine when the last time a specific machine last ran a process?

我可以使用以下内容来确定进程是否正在运行，但如果该进程已停止，则应用程序无法获取该进程.

I can use the following to determine if a process is running, but the application cannot grab the process if it has since stopped.

Process[] process = Process.GetProcessesByName(processName, serverName);

推荐答案

WMI 提供了一种方法来跟踪使用 Win32_ProcessTrace 类启动和终止的进程.最好用一个例子来说明.启动一个新的控制台应用程序，Project + Add Reference，选择 System.Management.粘贴此代码:

WMI provides a way to track processes starting and terminating with the Win32_ProcessTrace classes. Best shown with an example. Start a new Console application, Project + Add Reference, select System.Management. Paste this code:

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，以便此程序运行提升.然后只需启动一些程序即可查看它的工作情况.请注意，它不是特别快.

Edit the manifest so this program runs elevated. Then simply start some programs to see it at work. Beware that it is not especially quick.
