윈폼 어플리케이션에서 Beep 음 내기

How do I beep the computer's speaker in a Windows Form application

There is no Windows Form function to beep your computer's speaker. But you can just invoke the Win32 API MessageBeep.

using System.Runtime.InteropServices;

...

[DllImport("user32.dll")]

public static extern int MessageBeep(uint n);

private void button2_Click(object sender, System.EventArgs e)

{

MessageBeep(0x0);

}

Another method (suggested by msauper@sauper.com on microsoft.public.dotnet.framework.windowsforms)

Reference the VB.NET runtime support and just use the Beep() method.

The method is in:

Microsoft.Visual Basic.NET Runtime

The method is:

Microsoft.VisualBasic.Interaction.Beep();
