问题
My application needs to beep when validation fails so the user (who may be several feet away) may hear it. I'd like to use the Console.Beep() but this is unavailable in a x64 environment (see the remarks). There may or may not be speakers in/at the computer, so I can't use System.Media.SystemSounds.Beep.Play().
The current target platform is a x86 environment, but I'd like to have the ability for the application to run in x64 also.
Is there a way to do this or should I just give up?
Edit: Added link to the method.
回答1:
Beep has been removed as a native function from all x64 platforms (so no managed version of course), there was a Microsoft Connect issue that petitioned to return it.
We use a different trick to discover servers, we remote eject the dvd drive, and the drive with the tray open is the one were looking for :)
[EDIT]
Larry Osterman has a great article about this: What's up with the beep driver in Windows 7

Playing one of the standard windows sounds might be a better approach. The following article shows how (it only takes a couple lines):

If you wanted to stay within theme, you could check the windows registry for the current sound scheme, and play the appropriate sound to fit your need.

You can use the Console.Beep() method described here: https://msdn.microsoft.com/en-us/library/8hftfeyw(v=vs.110).aspx
Make sure that you run the executable as an administrator (escalated privileges)
