I've been given some code that I am calling through multicast delegate.
I would like to know how I can catch up and manage any exception raised there and that is not managed for the moment. I cannot modify the code given.
I've been looking around and found about the need to call GetInvocationList() but not really sure if this is helpful.
You can loop through all the delegates registed in the multicast list and call each of them in turn while wrapping each call in a try - catch block.
Otherwise the invocations of the subsequent delegates in the multicast after the delegate with the exception will be aborted.
The upvoted answer is for events, for delegates specifically try this extension method:
Consider the code using
GetInvocationList
:This my old approach, the newer approach I prefer is above because it makes invocation a snap, including the use of out/ref parameters (if desired).
which individually calls each delegate that would have been invoked with
Happy coding.
Remember to do the standard null-guard copy'n'check (and perhaps lock) when dealing with events.
