Decorate the function with an DllImport Attribute use the extern a static key words. You can look up API descriptions here : ms-help://MS.VSCC/MS.MSDNVS/win32/win32start_1xyd.htm [DllImport(Kernel32.dll EntryPoint=Beep)] private static extern bool MyBeep(int dwFreq int dwDuration); private void button5_Click(object sender System.EventArgs e) { MyBeep(500125); }
