Automapper: Using the structure returned by a custom resolver

Question

With AutoMapper, I am using a ValueResolver that returns a structure like this

struct MyStruct
{
        public int propA;
        public int propB;
                 


        

Answer 1

By using FromMember you can pass a property from the source to your ValueResolver.

You can use something like this:

.ForMember(dest => dest.SomePropA, opt=> opt.ResolveUsing().FromMember(src => src.propA))

If you don't specify FromMember, AutoMapper will pass the source to your ValueResolver.
