Make a sound

[#Hai]

I want to send out a small piece of sound (ex: a series of 5 beep) to the
speaker (by C#).
How to do that ?

[Michael Mayer]

I did a quick google search on "C# messagebeep"

Here's a hard way to do it (involves directx 9 sdk)
http://www.codeproject.com/csharp/MessageBeep.asp

And a few other good ways are listed in a message at:
http://www.csharpfriends.com/Forums/ShowPost.aspx?PostID=8811

From the 2nd URL, I think my own favorite would be this one (but then
again, i have no particularly bad feelings towards vb).
...you could call VB Runtime Beep like this.
Add referece to Microsoft Visual Basic.NET Runtime
//And then you just use this in your code:
Microsoft.VisualBasic.Interaction.Beep();

The simpler way do obtain the internal speaker beep is to use the
Beep(frequency,duration) function. In order to user it u got to import
kernel32.dll.

using System;
using System.Runtime.InteropServices;

class MainClass
{
[DllImport("kernel32.dll")]
public static extern bool Beep(int freq,int duration);

public static void Main(string[] args)
{
Console.WriteLine("un beep");
Beep(1000,1000);
Console.WriteLine("un beep più alto e più corto");
Beep(2000,500);
}
}

Method 1:

Method 2:

[DllImport("kernel32.dll")]
private static extern bool Beep(int frequency, int duration);
