在C＃编程杀死进程树

问题描述

我开始Internet Explorer的编程与code，它是这样的：

I am starting Internet Explorer programatically with code that looks like this:

ProcessStartInfo startInfo = new ProcessStartInfo("iexplore.exe");
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.Arguments = "http://www.google.com";
Process ieProcess = Process.Start(startInfo);

这会产生2个进程在Windows任务管理器中可见。于是，我试图杀掉进程：

This generates 2 processes visible in the Windows Task Manager. Then, I attempt to kill the process with:

ieProcess.Kill();

这导致被关闭在任务管理器的进程，并在其他遗迹之一。我试图检查，将有子进程的任何属性，但没有发现。我如何能杀死其他进程也？更一般地，你怎么杀你开始的Process.Start与进程相关联的所有进程？

This results in one of the processes in Task Manager being shut down, and the other remains. I tried checking for any properties that would have children processes, but found none. How can I kill the other process also? More generally, how do you kill all the processes associated with a process that you start with Process.Start?

推荐答案

这工作很漂亮对我来说：

This worked very nicely for me:

    /// <summary>
    /// Kill a process, and all of its children, grandchildren, etc.
    /// </summary>
    /// <param name="pid">Process ID.</param>
    private static void KillProcessAndChildren(int pid)
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher
          ("Select * From Win32_Process Where ParentProcessID=" + pid);
        ManagementObjectCollection moc = searcher.Get();
        foreach (ManagementObject mo in moc)
        {
            KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"]));
        }
        try
        {
            Process proc = Process.GetProcessById(pid);
            proc.Kill();
        }
        catch (ArgumentException)
        {
            // Process already exited.
        }
    }
