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

You don't want the action to have parameters, because the Dispatcher isn't going to know what to pass to the method. Instead what you can do is close over the variable:

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