从Windows服务（C＃）播放波形文件 [英] Play wave file from a Windows Service (C#)
问题描述
我需要从C＃应用程序的运行为Windows服务中发挥wav文件。我曾经尝试都System.Media.SoundPlayer和P / Invoke调用到WINMM.DLL（这可能是什么声音播放正在做）。
I need to play a wav file from a C# application running as a Windows Service. I have tried both System.Media.SoundPlayer and a P/Invoke call to WinMM.dll (which is probably what SoundPlayer is doing).
[DllImport("WinMM.dll")]
private static extern bool PlaySound(string fname, int Mod, int flag);
如果我跑我的code作为控制台应用程序，声音播放。当我从一个服务，没有运气运行它，我想我并不感到惊讶。
If I run my code as a console application, the sounds play. When I run it from a service, no luck, and I guess I'm not surprised.
那么，有没有打从一个窗口服务完善的一种方式？会像DirectSound的帮助吗？或者我会被卡住写一个控制台应用程序，并具有Windows服务的应用程序与它作为中介沟通？
So is there a way to play a sound from a windows service? Would something like DirectSound help? Or am I going to be stuck writing a console application and having the windows service app communicate with it as an intermediary?
在此先感谢
推荐答案
从服务播放wav文件是绝对有可能的，至少在Windows 7（和最有可能的Vista系统），通过使用Windows核心音频的API。我最近用做一个小的测试服务，验证了这一点 n音讯。我刚刚下载的n音讯来源，并从他们NAudioDemo项目复制WSAPI部分。这是在Windows 7企业版64位，但我不认为事情。该服务使用本地系统帐户。结果
为了记录在案，从服务播放声音是在嵌入式环境做一个完全合法的事情。
Playing a wav file from a service is definitely possible, at least on Windows 7 (and most likely Vista), by using the Windows Core Audio APIs. I recently verified this by making a small test service using NAudio. I just downloaded the NAudio sources and copied the "Wsapi" parts from their NAudioDemo project. This was on Windows 7 Enterprise 64bit, but I don't think that matters. The service was using the LocalSystem account.
For the record, playing sounds from a service is a perfectly legitimate thing to do in an embedded setting.
