How to run code before program exit? [duplicate]

问题

This question already has answers here:

Capture console exit C# (10 answers)

Closed 5 years ago.

I have a little console C# program like

Class Program 
{ 
    static void main(string args[]) 
    {
    }
}

Now I want to do something after main() exit. I tried to write a deconstructor for Class Program, but it never get hit.

Does anybody know how to do it.

Thanks a lot

Try the ProcessExit event of AppDomain:

using System;
class Test {
    static void Main(string[] args)
    {
        AppDomain.CurrentDomain.ProcessExit += new EventHandler (OnProcessExit); 
        // Do something here
    }

    static void OnProcessExit (object sender, EventArgs e)
    {
        Console.WriteLine ("I'm out of here");
    }
}
