Can a Delegate have an optional parameter?

Question

Answer 1

A delegate points to a method definition.
When you instantiate a delegate pointing to a method, you cannot specify any parameters.

Instead, you need to pass the parameter values to the Invoke method, like this:

SetUpdateHUDConnectedMode d = UpdateHUDConnectedMode;
this.Invoke(d, e.IsAvailable);
