// Demonstrates SetAudio, ContainsAudio, and GetAudioStream.
public System.IO.Stream SwapClipboardAudio(
System.IO.Stream replacementAudioStream)
{
System.IO.Stream returnAudioStream = null;
if (Clipboard.ContainsAudio())
{
returnAudioStream = Clipboard.GetAudioStream();
Clipboard.SetAudio(replacementAudioStream);
}
return returnAudioStream;
}
' Demonstrates SetAudio, ContainsAudio, and GetAudioStream.
Public Function SwapClipboardAudio( _
ByVal replacementAudioStream As System.IO.Stream) _
As System.IO.Stream
Dim returnAudioStream As System.IO.Stream = Nothing
If (Clipboard.ContainsAudio()) Then
returnAudioStream = Clipboard.GetAudioStream()
Clipboard.SetAudio(replacementAudioStream)
End If

End Function
Remarks
Use this method to determine whether the Clipboard contains audio data before retrieving it with the GetAudioStream method.
