Dispatch.Invoke( new Action…) with a parameter

Question

Previously I had

Dispatcher.Invoke(new Action(() => colorManager.Update()));

to update display to WPF from another thread. Due to design

Answer 1

If you call Invoke with an Action delegate, you need to pass the two Action parameters to the Invoke call:

ColorStreamManager colorManager = ...
ColorImageFrame frame = ...

Dispatcher.Invoke(
    new Action((p,v) => p.Update(v)),
    colorManager,
    frame);

The Invoke overload you're using here is Dispatcher.Invoke(Delegate, Object[]).
