强制外部进程在一段时间后被终止
我有一个从 C# 类库运行的命令行可执行文件。在极少数情况下,可执行文件会因传递给它的命令行数据而挂起。不幸的是,这会导致调用 c# DLL 的应用程序挂起,同时无限期地等待进程退出。
如果命令行 exe 没有在 1 秒内完成执行,它就永远不会退出。我想做的是在进程启动后立即生成一个计时器,如果进程在几秒钟内没有退出,则强制关闭该进程。
这里最好的方法是什么?该解决方案需要对性能产生最小的影响,因为此命令行进程是高度重复性任务的瓶颈。
编辑:为什么我应该使用 System.Timer 而不是 Threading.Timer,反之亦然?
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = false;
startInfo.UseShellExecute = true;
startInfo.WorkingDirectory = workingDirectory;
startInfo.FileName = commandLineExe;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.Arguments = strArguments;
// Call WaitForExit and then the using statement will close.
using (Process exeProcess = Process.Start(startInfo))
{
exeProcess.WaitForExit();
}
请避免提出我应该尝试找出命令行应用程序挂起的原因,或者我应该使用的建议将命令行功能重构到源代码中。我们正在积极解决这个问题,但应用程序的稳定性需要放在第一位。
I have a command line executable that is run from a C# class library. In some very rare situations the executable will hang because of the command line data passed to it. Unfortunetely this causes the application calling the c# DLL to hang whilst it waits indefinitely for the process to exit.
If the command line exe doesnt finish execution within 1 second its never going to exit. What I'd like to do is spawn a timer just after the process has started and force close the process if it hasnt exited within a few seconds.
What is the best approach here? The solution needs to have minimal impact upon performance because this command line process is the bottleneck in a highly repetitive task.
Edit: Any reason why I should use System.Timer rather than Threading.Timer or vice versa?
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = false;
startInfo.UseShellExecute = true;
startInfo.WorkingDirectory = workingDirectory;
startInfo.FileName = commandLineExe;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.Arguments = strArguments;
// Call WaitForExit and then the using statement will close.
using (Process exeProcess = Process.Start(startInfo))
{
exeProcess.WaitForExit();
}
Please refrain from suggestions that I should try and figure out why the command line app is hanging, or that I should refactor the command line functionality into the source code. We are actively working on that problem but stability of the application needs to come first.
