监控的过程的子进程 [英] Monitor child processes of a process

问题描述

我用这个code运行.exe文件：

 过程PROC =的Process.Start（C：\ PROGRAM.EXE）;
proc.WaitForExit（）;
 

如果我开始秒表在启动过程中和之后 proc.WaitForExit停止（）之前; 行，我可以使用该特定程序得到的时间为用户

我现在面临的问题是，一些程序（和游戏）使用发射器 - 一些小的.exe文件，通常检查一番，然后启动另一个.exe文件，实际上是程序/游戏，用户要运行。在这种情况下，code以上不工作，因为它返回发射后存在。

我怎么能跟踪所有程序PROC 运行，并等待单元1所有的人都将终止？

编辑：

下面是我的解决办法：

 公共静态类ProcessExtensions
{
    公共静态的IEnumerable＆lt;方法＆GT; GetChildProcesses（这个过程工艺）
    {
        清单＆lt;方法＆GT;孩子=新的List＆lt;方法＆GT;（）;
        ManagementObjectSearcher MOS =新ManagementObjectSearcher（的String.Format（SELECT * FROM Win32_Process的其中ParentProcessID = {0}，process.Id））;

        的foreach（的ManagementObject莫mos.Get（））
        {
            children.Add（Process.GetProcessById（Convert.ToInt32（MO [的ProcessID]）））;
        }

        返回儿童;
    }
}
 

解决方案

看看这个 - <一个href="http://stackoverflow.com/questions/7189117/find-all-child-processes-of-my-own-net-process-find-out-if-a-given-process-is">Find我自己的.NET进程的所有子进程/找出一个给定的过程是我自己的孩子呢？或<一href="http://social.msdn.microsoft.com/Forums/vstudio/en-US/d60f0793-cc92-48fb-b867-dd113dabcd5c/how-to-find-the-child-processes-associated-with-a-pid">http://social.msdn.microsoft.com/Forums/vstudio/en-US/d60f0793-cc92-48fb-b867-dd113dabcd5c/how-to-find-the-child-processes-associated-with-a-pid.他们提供的方法来查找父PID子进程（你有）。

您可以编写监视创建过程中，也得到了孩子们。然后，您可以跟踪一切，并等待他们全部完成。我说：试试，因为我不知道你能赶上非常迅速的变化（在这个过程开始别人，然后临死之前，你自己的孩子）。

I'm running .exe file using this code:

Process proc = Process.Start("c:\program.exe");
proc.WaitForExit();

If I start Stopwatch before starting the process and stop it after proc.WaitForExit(); line, I can get the time that user was using that particular program.

The problem I'm facing is that some programs (and games) use launchers - some small .exe file that usually checks something and then launches another .exe file that is actually the program/game that the user wants to run. In these cases the code above doesn't work because it returns after launcher exists.

How can I track all processes that proc runs, and wait unitl all of them are terminated?

EDIT:

Here is my solution:

public static class ProcessExtensions
{
    public static IEnumerable<Process> GetChildProcesses(this Process process)
    {
        List<Process> children = new List<Process>();
        ManagementObjectSearcher mos = new ManagementObjectSearcher(String.Format("Select * From Win32_Process Where ParentProcessID={0}", process.Id));

        foreach (ManagementObject mo in mos.Get())
        {
            children.Add(Process.GetProcessById(Convert.ToInt32(mo["ProcessID"])));
        }

        return children;
    }
}

解决方案

Take a look at this - Find all child processes of my own .NET process / find out if a given process is a child of my own? or http://social.msdn.microsoft.com/Forums/vstudio/en-US/d60f0793-cc92-48fb-b867-dd113dabcd5c/how-to-find-the-child-processes-associated-with-a-pid. They provide ways to find child processes by a parent PID (which you have).

You can write monitor the process you create and also get its children. You could then track everything, and wait for them all to finish. I say "try" because I'm not sure you could catch very rapid changes (a process starting others and then dying before you get his children).
