How would I use a pack uri resource with media player?

问题

I have some very simple code which just needs to play a sound with a specified volume, as follows :

var mp = new MediaPlayer();
mp.Open(uri);
mp.Volume = volume;
mp.Play();

The problem arises because this is part of a Prism module. I don't know where the executing assembly is going to be so I can't use a relative Uri or siteoforigin and MediaPlayer doesn't understand the pack Uri syntax.

I have a resource wav file at the root of my assembly called "notify.wav", but I have no way to pass it into MediaPlayer via a Uri and can't see any other way to load it.

How do I play the file?

回答1:

Since the resource is embedded and the MediaPlayer doesn't support pack uri, you'll need to read the resource in as a stream and write it out to file.You should then be able to load the file into the player as necessary.

I would write the file to my applications directory so that once extracted from the assembly, you can just reference the file directly.

Hope this helps

First you should declare a variable that is string for your media folder's path. This variable holds the path. just like:

string url = @"C:\Users\Alico\Documents\visual studio 2010\Projects\WpfBrushesTest\WpfBrushesTest\Dido - Thank You.mp4";

and then

mp.Open(new Uri(url,UriKind.Relative));

I’m afraid Media player does not support pack URI.

Have you tried Directory.GetCurrentDirectory or Environment.CurrentDirectory?
