1.使用Visual Basic Beep函數;添加引用 Miscorsoft Visual Basic Runtime
2.調用 Interaction.Beep();
<二>使用MessageBeep(unit uType):需添加 using System.Runtime.InteropServices;
public const int MB_ICONEXCLAMATION = 48;
[DllImport("user32.dll")]
public static extern bool MessageBeep(uint uType);
MessageBeep( MB_ICONEXCLAMATION );
<三>調用Beep(Int freq,int duration)函數
[DllImport("kernel32.dll")]
public static extern bool Beep(int freq,int duration);
Beep(800,300);
<四>調用PlaySound(string pszSound,int hmod,int fdwSound)
[DllImport("winmm.dll")]
public static extern bool PlaySound(string pszSound,int hmod,int fdwSound);
public const int SND_FILENAME = 0x00020000;
public const int SND_ASYNC = 0x0001;
PlaySound("提示時奏幻想空間.WAV",0,SND_ASYNC|SND_FILENAME);
