Check if MediaElement has a Source

When using a MediaElement's SetSource method, the media MediaElement's Source remains null. So how do we check if it has a source, that is, how do we check if Play will actually play something?

In addition to MediaOpened event MediaElement has also MediaFailed event which is raised when selected source can't be opened

To check if MediaElement has a valid Source, we can take advantage of MediaElement.MediaOpened event. This event occurs when the media stream has been validated and opened, and the file headers have been read. So if this event occurs, it must be able to actually play something.

Besides this event, we can also check MediaElement.CurrentState property, this property returns the current state of this MediaElement. The state can be one of the following (as defined in the MediaElementState enumeration): Buffering, Closed, Opening, Paused, Playing, or Stopped. The default value is Closed. And Closed represents the MediaElement contains no media. So while the current state is closed, It means there is no source and if the state is not closed, it should be able to play something.
