WPF Application Relative path to a mp3 sound file

10,295

The path must be relative to the folder where your application is executed.

mplayer.Open(new Uri(@"../../Sounds/circles.mp3", UriKind.Relative));

(Assuming your exe is run from the Bin/Debug folder)

    I'm building a WPF project with Visual Studio 2012 and I'm finding a problem with relative paths.

    In the specific, I want a sound to be played when a ToggleButton is checked.

    This is the code for my button:

    <ToggleButton Name="Circles" Margin="88,104,86,172" Background="#FFFFD0CD" Foreground="Black" Checked="Circles_Checked">Circles</ToggleButton>
    

    and if I write like this:

        private void Circles_Checked(object sender, System.Windows.RoutedEventArgs e)
        {
    
        MediaPlayer mplayer = new MediaPlayer();
    
        mplayer.Open(new Uri("C:\\Users\\user1\\Documents\\Visual Studio 2012\\Projects\\RehabilitationGUIProject\\RehabilitationGUIProject\\circles.mp3", UriKind.Relative));
    
        mplayer.Play();
        }
    

    everything works as espected. But I want this code to work also onto other machines, not only mine. And what If I have to move the sounds to another location? I would like to use relative paths and move every sound inside my project folder.

    So I created a new folder named Sound inside my root project, the structure is like this:

    RehabilitationGuiProject
    \Properties
    \References
    \Bin
    \Object
    \Sounds \circles.mp3

    ... other files .xaml

    So I wrote the same lines of code above, changing this one:

    mplayer.Open(new Uri(@"/Sounds/circles.mp3", UriKind.Relative));
    

    But no sound is played. Which is the correct relative path for playing sounds from a project folder?

    Instead of jumping out of the Debug folder (by prepending ../../) you can mark the mp3 file as "Content" and "Copy if newer" in the Visual Studio Solution Explorer. Visual Studio will then copy the mp3 file to the correct location.
