C＃-如果不支持Windows Media Player，则会发生错误

Question

i´m using the windows media player (Interop.WMPLib.dll & AxInterop.WMPLib.dll) in my c#-project to stream a mp3 from a server. The only problem is, if the windows media player is somehow not supported on a pc (not installed or something), my application just gives an error (no exception, just a "windows-error") and won´t start.

So, is it possible to check, if the windows media player is supported? Just checking if the OS is supported will probably not help.

Are there maybe some better ways to stream mp3s than with the WMP ?

Thanks in advance.

Answer 1

Look at the IsInstalled value under key HKLM\\Software\\Microsoft\\Active Setup\\Installed Components\\{22d6f312-b0f6-11d0-94ab-0080c74c7e95} OR HKLM\\Software\\Microsoft\\MediaPlayer\\ . It is 1 if installed .

OR Try a thirdparty player if you dont want to rely on WMP . VLC also has support for so many codecs .

I would like to extend this question one leve higher and solve absence of media player programatically because its unnecessary part of my solution. If interested please check https://stackoverflow.com/questions/17103532/optional-use-of-embed-wmp-on-windows-server
