Invoke Method

[TonyValenti]

I'd like to build an Event class that wraps a list of TDelegates and exposes a custom Invoke method that:

1. matches the signature of TDelegate
2. Does some pre/post processing on the list of delegates.

How do I accomplish #1?

I've done (1) by exposing public TDelegate Invoke { get; }. The language doesn't provide a facility to change a method signature based on the signature of a delegate type parameter.

Is there an ask for a language feature here?

Your three options are either 1) create a whole bunch of versions for each delegate signature (which is lots of repetition) or 2) use reflection to invoke the Invoke (pun intended) - basically takes params object[] args and passes it on (this is not type-safe) or 3) if possible, pass a delegate invocation delegate in: events.Run(d=>d(x, y, z))
