I need to pass by reference a boolean value to an event handler. Since 
passing arguments to event handler involve using an intermediate class 
deriving from EventArgs, the reference argument loose his reference aspect 
because bool is a value-type.

I need to pass a bool by reference to an event handler to implement default 
behaviour if no event handler is assigned and allow the event handler to 
select the action to be performed by setting the boolean value to true or 
false.

Actually it is a used in a communication application when a timeout is 
detected an event is triggered, passing a boolean "CanClose" initialized to 
"true". If no handler is assigned to the event, CanClose is true. If an 
event handler is assigned, it can select to change CanClose to false. Then 
is the component code, CanClose is used to close the socket or not to close 
it.

I designed a solution I don't like: I create a class with a boolean member 
and I used this class as argument type for my CanClose argument. Since class 
are always passed by reference, my event handler can change de boolean to 
whatever it likes, it is changed in the original class instance. So it does 
what I need but it is rather heavy code. Should be a better way to do that.
