C#进程重启循环 [英] C# process restart loop

问题描述

我正在尝试制作一个控制台应用程序，它可以监控某个进程并在它退出时重新启动它.因此，控制台应用程序始终处于开启状态，唯一的工作就是重新启动其他一些进程.

I'm trying to make a console app that would monitor some process and restart it if it exits. So, the console app is always on, it's only job is to restart some other process.

我在下面发布了我的代码......它基本上可以工作，但只是为了一个进程重启......

I posted my code below.. it basically works but just for one process restart...

我将不胜感激！

提前致谢！

    {
        System.Diagnostics.Process[] p = System.Diagnostics.Process.GetProcessesByName(SOME_PROCESS);
        p[0].Exited += new EventHandler(Startup_Exited);

        while (!p[0].HasExited)
        {
            p[0].WaitForExit();
        }

        //Application.Run();
    }

    private static void Startup_Exited(object sender, EventArgs e)
    {
        System.Diagnostics.Process.Start(AGAIN_THAT_SAME_PROCESS);  
    }

推荐答案

你需要一个循环，在循环的顶部你需要重新启动程序后将 p 重新附加到新的进程.所以就像:

You need a loop, and at the top of the loop you need to reattach p to the new process after restarting the program. So something like:

Process p = /* get the current instance of the program */;
while (true)
{
  p.WaitForExit();
  p = Process.Start(/* the program */);
}

请注意，由于 Process.Start 返回新实例的 Process 对象，您实际上不需要重新执行搜索:您可以直接等待新的 Process 对象.

Note that since Process.Start returns the Process object for the new instance, you don't actually need to re-perform the search: you can just wait directly on the new Process object.
