Console.Beep Method

Plays the sound of a beep through the console speaker.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

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


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 HostProtectionAttribute attribute applied to this type or member has the following Resources property value: UI. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

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.WriteLine("Usage: Enter the number of times (between 1 and 9) to beep.");
This example produces the following results:

Usage: Enter the number of times (between 1 and 9) to beep

Beep number 3.
Beep number 4.
Beep number 5.
