如何通过URI（WP7）访问IsolatedStorage中下载的声音？

Question

I basically downloaded a file name custom.mp3 into my isolatedstorage and I can see it via isolatedstorage explorer....

The question here is... How can I access the particular custom.mp3 via URI?

So far I got this.. but I wonder why it is not working:

alarm.Sound = new Uri("isostore:/custom.mp3", UriKind.Absolute);

Answer 1

Only files packaged in the XAML can be used as alarm sound:

Remarks

The Sound URI must point to a file packaged in the application's .xap file. Isolated storage is not supported. When the alarm is launched, the sound is played quietly and then gradually increases in volume. There is no way to modify this behavior.

From:

Alarm.Sound Property

Answer 2

Your path is wrong. Nothing else is wrong with your code. Post the code you're using for saving the mp3 file in the first place, if you want further help.

Answer 3

For easier reading, the code to store the MP3 goes something like this..

string alarmfile = "custom.mp3";
isolatedStorageFileStream = new IsolatedStorageFileStream(alarmfile,FileMode.Create,isolatedStorageFile);
long songfilelength = (long) e.Result.Length;
byte[] songbyte = new byte[songfilelength];
e.Result.Read(songbyte, 0, songbyte.Length);
isolatedStorageFileStream.Write(songbyte, 0, songbyte.Length);
isolatedStorageFileStream.Flush();
