In c#+VS2008+XP, I can play a wav file by calling

System.Media.SoundPlayer sp = new System.Media.SoundPlayer(new FileInfo( newfile).FullName); 


In year 2010 when I test it in Win7 and vista, I found it doesn't work at all(no sound from speaker and no exception from program).

However there is no problem when I play back this file in any players or in c++ Directshow and c++ soundplay();

Do anyone know how to solve this C# SoundPlayer problem?


Thanks in advanced

One possibility is that you have a wav file with a compressed format and the codec is missing in the system. Should not be a problem if it's plain PCM wave file

Hi,thanks for your hints, I am now checking file format.
You should not say "does not work" but report the problem properly.

I have tried both of the following methods on Windows 7 and they work fine;

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


String filename = "C:\\Windows\\Media\\chord.wav";
System.Media.SoundPlayer sp = new System.Media.SoundPlayer(new System.IO.FileInfo(filename).FullName);

thanks, your code works for me too, so I believe there is something wrong with my wav format.

Thanks all, the problem is solved, the problem is cause by the file format.

In my program , when I call


It will write {0x04,'d','a','t','a'}
but not {'d','a','t','a'} to the file which cause the format problem. Even it can be played in WindowsMediaPlayer, it will not work in soundplayer.
