声音播放不播放任何捆绑窗户的声音PCM WAV文件 [英] SoundPlayer not playing any bundled windows sounds PCM wav files

问题描述

在C＃中，我不能让声音播放类从System.Media从我的C播放任何WAV。我得到的是无声音：

In C# I cannot get SoundPlayer class from System.Media to play any wav from my C:\Windows\Media folder using the following code. All I get is no sound:

String filename = "C:\\Windows\\Media\\tada.wav";
SoundPlayer sp = new SoundPlayer(filename);
sp.Load();
sp.Play();

我已经检查了波形文件tada.wav有一个名为G点节目，告诉我的声音codeC是PCM音频。我没有收到任何编译器警告或错误，也没有当我运行程序产生的异常。我只是没有得到任何声音。我的发言是对的，我可以用Windows Media Player播放文件。

I have checked the wave file "tada.wav" with a program called "Gspot" that tells me the audio codec is "PCM Audio". I do not receive any compiler warnings or errors and there is no exceptions raised when I run the program. I just do not get any sound. My speakers are on, and I can play the file with Windows Media Player.

添加WAV作为项目资源没有任何区别。可能有人请帮我弄清楚，为什么我不能得到任何声音？

Adding the wav as a project resource does not make any difference. Could somebody please help me figure out why I cannot get any sound?

推荐答案

您使用此作为一个控制台应用程序中的main（）方法的主体？该应用程序可能结束，从而切断其播放音频线。

Are you using this as the body of a main() method in a console application? The application is probably ending, thereby shutting down the thread which plays the audio.

我复制并粘贴您的code到主的一个新的Visual C＃控制台应用程序。我添加了使用System.Text;在文件，编译的顶线，加大通过它，和它的工作。当我跑了（没有调试）我没有声音。

I copied and pasted your code into the main of a new "Visual C# Console Application". I added the "using System.Text;" line at the top of the file, compiled, stepped through it, and it worked. When I ran it (without debugging) I got no sound.

如果您添加一行：

System.Threading.Thread.Sleep（2000年）;

System.Threading.Thread.Sleep(2000);

在调用播放（），应用程序将保持足够长的时间来播放音频。

After the call to Play(), the application will stay around long enough to play the audio.
