Playing media file from Isolated Storage in windows phone?

问题

I need to play music file from the isolated storage. i did by this way,

MediaElement media = new MediaElement();

using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())

{
    using (IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile(FileName, FileMode.Open, FileAccess.Read))
    {
         media.SetSource(fileStream);
         media.Play();
    }
}

I can't play the music file. When i created media element Xaml and set source that element this works fine. The problem is, i have to create all controls dynamically.

Pls suggest me how to resolve this pblm...

Thanks

You need to add this MediaElement to your visual tree. Or in other words the MediaElement should be part of your PhoneApplicationPage.

Assume you have a Grid inside your page and add this MediaElement to the grid.

grid.Children.Add(media);

And then you can set the Source as well as Play() the media.
