I
needed to create a class with a collectiont that would raise events when items
where added or removed to it. It was the work of a few minutes to add the events
and then write this code:
outputs = new EntitySet<IConnection>(
delegate(IConnection connection) { Raise(OutputAdded,
connection); },
delegate(IConnection connection) { Raise(OutputRemoved,
connection); }
);
Where
Raise() looks like this:
private void Raise(EventHandler<ConnectionEventArgs> eventToRaise, IConnection connection)
{
ConnectionEventArgs args = new ConnectionEventArgs(connection);
if (eventToRaise != null)
eventToRaise(this, args);
}
It
starting too look like O/RM and frieds are the first tools that I pool out of
the toolbox.
