Question

Hello How to create a List<SystemSound> with music from recourses?

I try this, but i get below exception:

    List<System.Media.SystemSound> music = new List<System.Media.SystemSound>
    {
        global::Launcher.Properties.Resources.music_quit_1,
        global::Launcher.Properties.Resources.music_quit_2,
        global::Launcher.Properties.Resources.music_quit_3,
        global::Launcher.Properties.Resources.music_quit_4,
    };

“Argument 1: Can not convert from System.IO.UnmanagedMemoryStream to
System.Media.SystemSound.”

From that I will random on music and after play it.

Answer 1

The class System.Media.SystemSound is not used this way, this class is only used to represent a system sound type such as Asterisk, Beep, Hand, Question or Exclamation. A system sound can be played through SystemSounds.

Example

SystemSounds.Asterisk.Play();

This example will play the system sound Asterisk. This is similar to System.Drawing.Brush as you can not say System.Drawing.Brush.Black but you can say System.Drawing.Brushes.Black. System.Drawing.Brush was only used to define an object of name Black in a new class of name System.Drawing.Brushes as a color Black. We can see this in the definition of System.Drawing.Brushes

//
// Summary:
//     Gets a system-defined System.Drawing.Brush object.
//
// Returns:
//     A System.Drawing.Brush object set to a system-defined color.
public static Brush Black { get; }

Moreover, if you would like to play a new Wave Sound, you may create a new class of SoundPlayer which controls playback of a sound from a Sound Wave(.wav) file

Example

SoundPlayer _SoundPlayer = new SoundPlayer(); //Initializes a new SoundPlayer of name _SoundPlayer
_SoundPlayer.SoundLocation = @"D:\Resources\International\Greetings.wav"; //Sets the target Wave Sound file to D:\...\Greetings.wav
_SoundPlayer.Play(); //Plays the target Wave Sound file

If you still would like to use a Generic List. Then, perhaps the following example may help you

Example

List<string> WaveSoundCollections = new List<string> { @"D:\Resources\International\Greetings.wav", @"D:\Resources\International\Good-Bye.wav" }; //Initializes a new Generic Collection of class List of type string and injecting TWO strings into the Generic Collection
SoundPlayer NewPlayer = new SoundPlayer(); //Initializes a new SoundPlayer
if (Client.Start) //Client refers to a particular Class that has Start and End as bool
{
    NewPlayer.SoundLocation = WaveSoundCollections[0]; //Set the SoundLocation of NewPlayer to D:\Resources\International\Greetings.wav
    NewPlayer.Play(); //Plays the target Wave Sound file
}
else if (Client.End)
{
    NewPlayer.SoundLocation = WaveSoundCollections[1]; //Set the SoundLocation of NewPlayer to D:\Resources\International\Good-Bye.wav
    NewPlayer.Play(); //Plays the target Wave Sound file
}

Notice: SoundPlayer is only used to play Wave Sound files. If you would like to play other media files such as .mp3, .mpeg, etc… Then, you may use System.Windows.Media.MediaPlayer which can be imported from the Object Browser to create a new class of MediaPlayer and play a particular file.

Example

string TargetFile = @"D:\File.mp3";
MediaPlayer _MediaPlayer = new MediaPlayer();
_MediaPlayer.Open(new Uri(TargetFile));
_MediaPlayer.Play();

IMPORTANT: To use MediaPlayer, you have to add a new reference of WindowsBase.

To add a new reference of WindowsBase, try the following:

• Right-click References from the Solution Explorer and select Add Reference…
• Select WindowsBase and click on OK

• Make sure that the new reference you’ve just added has its property of bool of name Copy Local set to True so that the client won’t encounter errors during initialization

   

Thanks,

I hope you find this helpful 🙂
