Loads a .wav file from a stream or a Web resource using a new thread.

Namespace: System.Media
Assembly: System (in system.dll)

public void LoadAsync ()
public void LoadAsync ()
public function LoadAsync ()
Not applicable.

Exception typeCondition


The elapsed time during loading exceeds the time, in milliseconds, specified by LoadTimeout.


The file specified by SoundLocation cannot be found.

If a SoundPlayer is configured to load a .wav file from a Stream or Web resource, this method begins loading a .wav file from the location using a new thread.

This method raises the LoadCompleted event when loading completes, even if the load was not successful.

If a SoundPlayer is configured to load a .wav file from a local file path, this method does nothing, because loading is deferred until playing begins.

For more information about asynchronous loading, see How to: Load a Sound Asynchronously within a Windows Form.

The following code example demonstrates the use of the LoadAsync method to asynchronously load a .wav file for use by an instance of the SoundPlayer class. This code example is part of a larger example provided for the SoundPlayer class.

    // Assign the selected file's path to 
    // the SoundPlayer object.  
    player.SoundLocation = this.filepathTextbox.Text;

    // Load the .wav file.
