• Converting DTOs to View Models

  - by illvm

  Does anyone know of a good (read: quick to code) method for converting DTOs to View Models or mapping DTO members to View Model members? Lately I've been finding myself writing many conversion and helper methods but this is a very arduous and tedious task. Moreover, it will often needs to be done twice (DTO - View Model, View Model - DTO). Is there a methodology, technique, or technology which would allow me to do this more quickly and efficiently?

• When should I use a struct instead of a class?

  - by Esteban Araya

  MSDN says that you should use structs when you need lightweight objects. Are there any other scenarios when a struct is preferable over a class? Edit: Some people have forgotten that: 1. structs can have methods! 2. structs have no inheritance capabilites. Another Edit: I understand the technical differences, I just don't have a good feel for WHEN to use a struct.

  To use methods of a class I need to instantiate a class. At the moment the class has not constructor (so I want to write it).

• Is there a better way than a sequence of if's to handle events?

  - by Matt

  I recently ran across several objects implemented to handle events with a hard coded mapping using this pattern: public void handleEvent(Event event) { if(event.getCode() == SOME_STATIC_EVENT) doSomething(event); if(event.getCode() == ANOTHER_STATIC_EVENT) doSomethingElse(event); } where doSomething functions are implemented as methods of the same class. In hopes of striving for looser coupling, how would you suggest abstracting out this pattern? Also, what's the best approach for mapping 0..N functions to a fired event?
