　　函数

<一>Visual Basic Beep()

1.使用Visual Basic Beep函数；添加引用 Miscorsoft Visual Basic Runtime

2.调用 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>调用Beep(Int freq,int duration)函数

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

Beep(800,300);

<四>调用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("提示时奏幻想空间.WAV",0,SND_ASYNC|SND_FILENAME);
