如何在.Net中播放"New Mail"系统声音？

Question

如何在C#中播放"New Mail"系统声音？这也称为"通知"声音.

在Win32中,这将是类似的

sndPlaySound('Notify', (SND_ALIAS or SND_ASYNC));

那么你如何在.Net中做到这一点？我知道你可以做到

System.Media.SystemSounds.Asterisk.Play();

但是那里有五种声音非常有限 - 不包括用户设置的新邮件声音.

当我收到新邮件并播放该文件时,我可以找出正在播放的.wav文件,但是当用户的声音方案发生变化时,这不会更新.

我最终做了什么:

我没有播放系统声音,而是将wav文件作为资源嵌入到应用程序中,然后播放它 System.Media.SoundPlayer

一种选择是直接将PInvoke直接导入sndSound API.这是该方法的PInvoke定义

public partial class NativeMethods {

    /// Return Type: BOOL->int
    ///pszSound: LPCWSTR->WCHAR*
    ///fuSound: UINT->unsigned int
    [System.Runtime.InteropServices.DllImportAttribute("winmm.dll", EntryPoint="sndPlaySoundW")]
    [return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
public static extern  bool sndPlaySoundW([System.Runtime.InteropServices.InAttribute()] [System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.LPWStr)] string pszSound, uint fuSound) ;

    /// SND_APPLICATION -> 0x0080
    public const int SND_APPLICATION = 128;

    /// SND_ALIAS_START -> 0
    public const int SND_ALIAS_START = 0;

    /// SND_RESOURCE -> 0x00040004L
    public const int SND_RESOURCE = 262148;

    /// SND_FILENAME -> 0x00020000L
    public const int SND_FILENAME = 131072;

    /// SND_ALIAS_ID -> 0x00110000L
    public const int SND_ALIAS_ID = 1114112;

    /// SND_NOWAIT -> 0x00002000L
    public const int SND_NOWAIT = 8192;

    /// SND_NOSTOP -> 0x0010
    public const int SND_NOSTOP = 16;

    /// SND_MEMORY -> 0x0004
    public const int SND_MEMORY = 4;

    /// SND_PURGE -> 0x0040
    public const int SND_PURGE = 64;

    /// SND_ASYNC -> 0x0001
    public const int SND_ASYNC = 1;

    /// SND_ALIAS -> 0x00010000L
    public const int SND_ALIAS = 65536;

    /// SND_SYNC -> 0x0000
    public const int SND_SYNC = 0;

    /// SND_LOOP -> 0x0008
    public const int SND_LOOP = 8;

    /// SND_NODEFAULT -> 0x0002
    public const int SND_NODEFAULT = 2;
}
