So I tend to develop things in the way of
- Make it work
- Make it pretty
Make it work
So when using AutoMapper after step one I ended up with something like this
Some background, for the destination SomeSource I needed to Deserialize the value as it was currently stored as Json in my database.
Make it pretty
So, first I added a custom ValueResolver that looked like this
Next was to connect AutoMapper with AutoFac and to register the ValueResolver:
Once that is done the last thing to change is to modify the ForMember call to use the new ValueResolver instead
Looks a lot cleaner and follows the flow that you would expect when using a IoC container.
If you don’t want to have calls to the static
Mapper.Map<> all over your code, it is possible to register the IMappingEngine in AutoMapper in you IoC container and have that as an dependency for you class too. For AutoFac the registration looks like this
The important thing is to register it as a singelton. Once that is done just add
IMappingEngine mappingEngine to the constructors of those classes that use AutomMapper.
