I'm developing a ClassLibrary with MVP architecture for create our internal
applications easier.
I've added several interesting features and now, I wanted add it a
centralized exception management with Dynamic Proxy:
I would like that for any exception in any view, any presenter or any
service several actions are made: register exception in event
viewer, send a mail to Help Desk, ... event show exception message to user
could be also considered an action like these.
My question is, which option is best? (Or none? Buaaaaaa!)
A:
Create IErrorHandle interface with "Handle(Exception ex)" operation and an
implementation for "action": event viewer, mail,
messagebox, ...
Then, create A SINGLE INTERCEPTOR with a List<IErrorHandle>, and in
Intercept method, simple code like this:
Try
invocation.Proceed()
Return
Catch ex As Exception
For Each h In _errorHandlers
h.Handle(ex, invocation)
Next
End Try
B:
Create ONE INTERCEPTOR PER ACTION: EventViewerInterceptor, MailInterceptor,
MessageBoxInterceptor, ...
IErrorHandle would not be required.
