Getting the right WPF dispatcher in a thread [duplicate]

Question

In the constructor of an object i need to create a WPF mediaElement object:

m_videoMedia = new MediaElement();

but the class can also be instantiated from a other thread so i need to use

Dispatcher.Invoke(DispatcherPriority.Normal,
    (Action)(() => { m_videoMedia = new MediaElement(); })); 

But how can I get the right dispatcher instance in that constructor :s

Answer 1

You most likely can just use Dispatcher.CurrentDispatcher.Invoke...

However, if for some reason that doesn't work, you could have your class receive a reference to the Dispatcher as part of its constructor. Just pass in Dispatcher.CurrentDispatcher from the UI thread at construction time.
