| HostProtectionException | This method was executed on a server, such as SQL Server, that does not permit access to a user interface. |
By default, the beep plays at a frequency of 800 hertz for a duration of 200 milliseconds.

The Beep method is not supported on the 64-bit editions of Windows Vista and Windows XP. |
The following example demonstrates the Beep method. The example accepts a number from 1 through 9 as a command line argument, and plays the beep that number of times.
' This example demonstrates the Console.Beep() method.
