/// </Summary>
Public class apifunctions
{
/// <Summary>
/// PCI speaker frequency
/// </Summary>
Public const int freq= 2000;
/// <Summary>
/// Duration of the PCI Horn
/// </Summary>
Public const int duration= 1000;

[Dllimport ("kernel32.dll", entrypoint = "beep")]
Public static extern int BEEP (INT dwfreq, int dwduration );

/// <Summary>
/// Send a voice notification to the user through this method
/// </Summary>
Public static void collatebeep ()

Beep (freq, duration );

Call:

Apifunctions. collatebeep ();
