How to: Load a Sound Asynchronously within a Windows Form
The following code example asynchronously loads a sound from an URL and then plays it on a new thread.
Example
[!code-csharpSystem.Media.SoundPlayer.LoadAsync#1] [!code-vbSystem.Media.SoundPlayer.LoadAsync#1]
Compiling the Code
This example requires:
-
References to the System and System.Windows.Forms assemblies.
-
That you replace the file name
"http://www.tailspintoys.com/sounds/stop.wav"with a valid file name.
Robust Programming
File operations should be enclosed within appropriate exception-handling blocks.
The following conditions may cause an exception:
-
The path name is malformed. For example, it contains characters that are not valid or is only white space (xref:System.ArgumentException class).
-
The path is read-only (xref:System.IO.IOException class).
-
The path name is
Nothing(xref:System.ArgumentNullException class). -
The path name is too long (xref:System.IO.PathTooLongException class).
-
The path is not valid (xref:System.IO.DirectoryNotFoundException class).
-
The path is only a colon ":" (xref:System.NotSupportedException class).
.NET Framework Security
Do not make decisions about the contents of the file based on the name of the file. For example, the file Form1.vb may not be a Visual Basic source file. Verify all inputs before using the data in your application.
