How can I make the computer beep in C#?

Question

How do I make the computer\'s internal speaker beep in C# without external speakers?

Answer 1

It is confirmed that Windows 7 and newer versions (at least 64bit or both) do not use system speaker and instead they route the call to the default sound device.

So, using system.beep() in win7/8/10 will not produce sound using internal system speaker. Instead, you'll get a beep sound from external speakers if they are available.
