如何在不终止进程的情况下处理System.Diagnostics.Process对象? [英] How to dispose a System.Diagnostics.Process object without killing process?

问题描述

我有一个创建Process对象以启动外部应用程序的应用程序.一旦它验证了应用程序已正确启动，就不再在乎它了，因此不再需要Process对象，但是由于不想关闭进程，所以无法对其调用Dispose().解决方法是什么?

I have an application that creates Process objects in order to launch external applications. Once it verifies the application has launched correctly, it no longer cares about it, so I don't need the Process object any longer, but I can't call Dispose() on it because I don't want to shutdown the process. What is the workaround for this?

推荐答案

您可以安全地处理流程实例，该流程将在之后运行.

You can safely Dispose the process instance, the process will run after.

class Program
{
    static void Main(string[] args)
    {
        Process p = new Process
        {
            StartInfo = {FileName = "notepad.exe"}
        };
        p.Start();

        p.Dispose();
        // Notepad still runs...
        GC.Collect(); // Just for the diagnostics....
        // Notepad still runs...
        Console.ReadKey();
    }
}

实际上，该过程(Notepad.exe)甚至会在您的.NET应用终止后运行.顺便说一句，这是我建议不要担心Process实例并在实际终止之前将其处置的原因之一:您将失去控制手柄以停止OS进程或查询其状态.除非您有无数的Process实例，否则我不必担心它们.

Actually the process (Notepad.exe) will even run after your .NET app was terminated. Btw that's one of the reason I recommend not to worry about the Process instances and disposing them before the process actually terminated: You will lost your control handle to stop the OS processes or query their status. Unless you have zillion of Process instances I should not worry about them.
