[HostProtectionAttribute(SecurityAction.LinkDemand, UI = true)]
public static void Beep()

Exception Condition
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.

System_CAPS_noteNote

The Beep method is not supported on the 64-bit editions of Windows Vista and Windows XP.

Beep wraps a call to the Windows Beep function. Whether Beep produces a sound on versions of Windows before Windows 7 depends on the presence of a 8254 programmable interval timer chip. Starting with Windows 7, it depends on the default sound device.

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.
using System;

class Sample 
{
    public static void Main(String[] args) 
    {
    int x = 0;
//
    if ((args.Length == 1) &&
        (Int32.TryParse(args[0], out x) == true) &&
        ((x >= 1) && (x <= 9)))
        {
        for (int i = 1; i <= x; i++)
            {
            Console.WriteLine("Beep number {0}.", i);
            Console.Beep();
            }
        }
    else
        Console.WriteLine("Usage: Enter the number of times (between 1 and 9) to beep.");
    }
}
