as the creator of ValueInjecter, I can tell you that I did it because I wanted something simple and very flexible I really don’t like writing much or writing lots of monkey code like: Prop1.Ignore, Prop2.Ignore etc. CreateMap<Foo,Bar>(); CreateMap<Tomato, Potato>(); etc. ValueInjecter is something like mozilla with it’s plugins, you create ValueInjections and use them … Read more
Method Condition now has five overloads, one of which accepts predicate of type Func<TSource, TDestination, TMember, bool> this TMember parameter is the source member. So you can check source member for null: CreateMap<StatusLevelDTO, StatusLevel>() .ForAllMembers(opts => opts.Condition((src, dest, srcMember) => srcMember != null));
Doesn’t matter, as long as it’s a static class. It’s all about convention. Our convention is that each “layer” (web, services, data) has a single file called AutoMapperXConfiguration.cs, with a single method called Configure(), where X is the layer. The Configure() method then calls private methods for each area. Here’s an example of our web … Read more
You cannot directly map many sources to single destination – you should apply maps one by one, as described in Andrew Whitaker answer. So, you have to define all mappings: Mapper.CreateMap<People, PeoplePhoneDto>(); Mapper.CreateMap<Phone, PeoplePhoneDto>() .ForMember(d => d.PhoneNumber, a => a.MapFrom(s => s.Number)); Then create destination object by any of these mappings, and apply other mappings … Read more
Use ConstructUsing this will allow you to specify which constructor to use during the mapping. but then all of the other properties will be automatically mapped according to the conventions. Also note that this is different from ConvertUsing in that convert using will not continue to map via the conventions, it will instead give you … Read more
Use the overload that takes the existing destination: Mapper.Map<Source, Destination>(source, destination); Yes, it returns the destination object, but that’s just for some other obscure scenarios. It’s the same object.
I figured it out! Here’s the details: Add the main AutoMapper Package to your solution via NuGet. Add the AutoMapper Dependency Injection Package to your solution via NuGet. Create a new class for a mapping profile. (I made a class in the main solution directory called MappingProfile.cs and add the following code.) I’ll use a … Read more
While @Aaronaught’s answer was correct at the time of writing, as often the world has changed and AutoMapper with it. In the mean time, QueryableExtensions were added to the code base which added support for projections that get translated into expressions and, finally, SQL. The core extension method is ProjectTo1. This is what your code … Read more
From Jimmy Bogard: CreateMap<Foo, Bar>().ForMember(x => x.Blarg, opt => opt.Ignore()); It’s in one of the comments at his blog. UPDATE(from Jamie’s comment Jan 4 ’19 at 11:11:) Ignore has been replaced with DoNotValidate in ForSourceMember: https://github.com/AutoMapper/AutoMapper/blob/master/docs/8.0-Upgrade-Guide.md
From what I understood the question was that there are fields on the destination which doesn’t have a mapped field in the source, which is why you are looking for ways to Ignore those non mapped destination fields. Instead of implementing and using these extension method you could simply use Mapper.CreateMap<sourceModel, destinationModel>(MemberList.Source); Now the automapper … Read more
