Merge two objects to produce third using AutoMapper
I know it's AutoMapper and not AutoMerge(r), but...
I've started using AutoMapper and have a need to Map A -> B, and to add some properties from C so that B become a kind of flat composite of A + C.
Is this possible in AutoMapper of should I just use AutoMapper to do the heavy lifting then manually map on the extra properties?
你可以用ValueInjecter来做到这一点
a.InjectFrom(b)
.InjectFrom(c)
.InjectFrom<SomeOtherMappingAlgorithmDefinedByYou>(dOrBOrWhateverObject);
这不行吗？
var mappedB = _mapper.Map<A,B>(aInstance);
_mapper.Map(instanceC,mappedB);
From what I remember with AutoMapper you have to define your mappings as one input to one output (maybe this has changed since - haven't utilized it for many a month).
If this is the case, maybe your mapping should be of KeyValuePair<A,C> (or some sort of object composing both A & C) => B
This way you can have one defined input parameter mapping to your outputted object
