问题:如何确定子进程树中的所有进程并杀死它们?
我有一个用 C# 编写的应用程序,它将:
- 从服务器获取一组数据,
- 生成第 3 方实用程序来处理数据,然后
- 将结果返回到服务器。
这工作正常。 但由于一次运行会消耗大量 CPU 并且可能需要长达一个小时的时间,因此我想添加让我的应用终止其子进程的功能。
我在其他地方找到的简单解决方案的一些问题是:
- 我的应用程序的子进程“A”(我认为是InstallAnywhere EXE)生成了真正的处理应用程序“B”(一个java.exe),它依次生成更多子项“C1”..“Cn”(其中大部分也是用 Java 编写的)。
- 我的应用程序可能会在同一台计算机上运行多个副本(因此,其子级的多组)。
- 子进程不在我的控制范围内,因此将来可能会出现一些“D”进程。
- 我的应用程序必须在 32 位和 64 位版本的 MSWindows 上运行。
从好的方面来说,不存在数据丢失的问题,只要进程相当快地结束,“干净”的关闭并不重要。
Question: How can I determine all processes in the child's Process Tree to kill them?
I have an application, written in C# that will:
- Get a set of data from the server,
- Spawn a 3rd party utility to process the data, then
- Return the results to the server.
This is working fine. But since a run consumes a lot of CPU and may take as long as an hour, I want to add the ability to have my app terminate its child processes.
Some issues that make the simple solutions I've found elsewhere are:
- My app's child process "A" (InstallAnywhere EXE I think) spawns the real processing app "B" (a java.exe), which in turns spawns more children "C1".."Cn" (most of which are also written in Java).
- There will likely be multiple copies of my application (and hence, multiple sets of its children) running on the same machine.
- The child process is not in my control so there might be some "D" processes in the future.
- My application must run on 32-bit and 64-bit versions of MSWindows.
On the plus side there is no issue of data loss, a "clean" shutdown doesn't matter as long as the processes end fairly quickly.

我猜你可以用 MSDN 论坛。
I guess you can kill your grandchildren with this code from the MSDN forums.
根据本网站概述的解决方案,以下是一种紧凑的方法:
Based on the solution outlined on this site, here is a compact way of doing it:
以下代码适用于我:
它适用于我的场景。 我很想知道这是否也适用于其他人。
The following code works for me:
It works for the scenario I have. I'd be interested to hear if that works for others as well.
我测试了杰克·皮尔森的解决方案,对我来说这并不总是有效。 我想杀死其他进程(具有已知的 pid)树。 另一个进程使用 iexplore.exe 为每个实例单独运行(IE 8 - 多个进程)。 它工作正常,但当与 WinAPI 一起使用来隐藏 IE 窗口时,它停止工作。
我在microsoft.public.dotnet.framework 群组上找到了解决方案,现在工作正常了。 尽管我认为杰克的回答在大多数情况下都是有用的。
I tested Jake Pearson's solution and for me this does not always work. I wanted to kill other process (with known pid) tree. The other process was using iexplore.exe running separately for each instance (IE 8 - more than one process). It works fine, but when used with WinAPI to hide IE window it stopped working.
I found solution on microsoft.public.dotnet.framework group, and it works fine now. Although Jake's answer can be useful in most cases, I think.
