Why TextWriterTraceListener can't work in release mode?

Question

This program can work on debug mode but can't work on release mode:

 static void Main(string[] args)
    {
        Trace.Listeners.Add(new TextWriterTraceListener(@"c:\prog\a.txt"));
        Debug.AutoFlush = true;
        Debug.WriteLine("abc");
        Debug.Close();
    }

When this program run in release mode,it can work without error,but can't write line "abc" in a.txt Can you teach me why?Thanks

What do you mean by can't work? Do you get any error or something like that? Please provide more information. — Vadim Iarovikov, Nov 06 '17 at 08:20
There is no error,but the prog can't write "abc" in a.txt when using realse mode — wang kai, Nov 06 '17 at 08:21
You're using Debug to write to it, and Debug doesn't work in release mode. It's meant to write things you don't want to see in release mode. Use `Trace.WriteLine` and it'll work. — Jesper, Nov 06 '17 at 08:23

Because you are using

Debug.WriteLine("abc")

Which will not compile when building in release mode, use instead :

Trace.WriteLine("abc")

Note also that Trace wil execute on both modes of building.
