Using ValueInjecter to map between objects with different property names

Question

How do I map a property from an object to another object with a different property name?

I have a Product class that looks like this:

public         


        

Answer 1

If you are using ValueInjecter then you would write a ConventionInjection. See the second sample here

    public class PropToTypeProp : ConventionInjection
    {
        protected override bool Match(ConventionInfo c)
        {
            return c.TargetProp.Name == c.Source.Type.Name + c.TargetProp.Name;
        }
    }

this injection will do from all properties of TSource.* to TTarget.TSource+*, so you do:

vm.InjectFrom<PropToTypeProp>(product);

Answer 2

You can do this easily with AutoMapper. By default is uses convention (i.e. Id maps to Id and Name to Name), but you can also define custom mappings.

Mapper.CreateMap<Product, ProductSpecificationAddViewModel>()
    .ForMember(destination => destination.ProductName,
               options => options.MapFrom(
                    source => source.Name));

Your contoller mapping code will be then this simple :

Mapper.Map(product, viewModel);
