Dictionary of events?

Is there a way to create a dictionary of event objects How

This is what I have:

public delegate void MyDelegate();

This is the type of thing I would like:

private Dictionary<Object, event MyDelegate> listeners;

Is something like that possible I know I could use a List<MyDelegate> instead of an event but I would rather use the event for obvious reasons.

Thanks.

    Got it. Thanks. I didn't know the += operator was available for delegates.

  • Gaurav Srivastava

    try Dictionary<Object, MyDelegate>.

    No. It holds a list. A delegate is implicitly derived from MultiCast delegate. Therefore you should be able to call += new EventHandler(...) several times on every entry of your dictionary. Try it.

    If you're doing what I think you're trying and if they haven't fixed the problem in RTM then any events/delegates used with generics have extremely bad performance. There are several bugs listed on the feedback site (if it's still up and operational) about this.

    But then it is just holding a single delegate object per key. I want to hold a list of delegate (preferably as an event). Am I missing something

  • Guy_Dupre

    What do you think I am doing I am attempting to create a collection of event objects. I would like to use the generic Dictionary class to maintain the collection but I don't know how to add declare the collection since the compiler won't allow either Dictionary<Object, event MyDelegate> or Dictionary<Object, event>.

    That you state that there is a bug a performance issues seems to suggest that it is possible to do the above, however I cannot figure out the syntax that will allow it to compile.
