public:
 void PlaySync();
public void PlaySync ();
member this.PlaySync : unit -> unit
Public Sub PlaySync ()

Exceptions

TimeoutException

FileNotFoundException

The file specified by SoundLocation cannot be found.

InvalidOperationException

The .wav header is corrupted; the file specified by SoundLocation is not a PCM .wav file.

Examples

The following code example demonstrates the use of the PlaySync method to synchronously play a .wav file.

private:
   SoundPlayer^ Player;

   void loadSoundAsync()
   {
      // Note: You may need to change the location specified based on
      // the location of the sound to be played.
      this->Player->SoundLocation = "http://www.tailspintoys.com/sounds/stop.wav";
      this->Player->LoadAsync();
   }

   void Player_LoadCompleted( Object^ /*sender*/, System::ComponentModel::AsyncCompletedEventArgs^ /*e*/ )
   {
      if (this->Player->IsLoadCompleted)
      {
         this->Player->PlaySync();
      }
   }

private SoundPlayer Player = new SoundPlayer();
private void loadSoundAsync()
{
    // Note: You may need to change the location specified based on
    // the location of the sound to be played.
    this.Player.SoundLocation = "http://www.tailspintoys.com/sounds/stop.wav";
    this.Player.LoadAsync();
}

private void Player_LoadCompleted (
    object sender, 
    System.ComponentModel.AsyncCompletedEventArgs e)
{
    if (this.Player.IsLoadCompleted)
    {
        this.Player.PlaySync();
    }
}

Private WithEvents Player As New SoundPlayer

Sub LoadSoundAsync()
    ' Note: You may need to change the location specified based on
    ' the location of the sound to be played.
    Me.Player.SoundLocation = "http://www.tailspintoys.com/sounds/stop.wav"
    Me.Player.LoadAsync ()
End Sub

Private Sub PlayWhenLoaded(ByVal sender As Object, ByVal e As _
    System.ComponentModel.AsyncCompletedEventArgs) Handles _
    Player.LoadCompleted
    If Me.Player.IsLoadCompleted = True Then
            Me.Player.PlaySync()
    End If
End Sub

Remarks

The PlaySync method uses the current thread to play a .wav file, preventing the thread from handling other messages until the load is complete. You can use the LoadAsync or Load method to load the .wav file to memory in advance. After a .wav file is successfully loaded from a Stream or URL, future calls to playback methods for the SoundPlayer will not need to reload the .wav file until the path for the sound changes.

If the .wav file has not been specified or it fails to load, the PlaySync method will play the default beep sound.
