具有多个ITypeConverter实现的automapper ConvertUsing

Question

I have a typeconverter class that implements ITypeConverter for both an object and for a pager (inheriting IEnumerable) of the objects. eg

   class MyConverter : ITypeConverter<IFoo, FooModel>,
                       ITypeConverter<IPager<IFoo>, IPager<FooModel>>
    {
        public FooModel Convert(IFoo source, FooModel destination, ...) {...}
        public IPager<FooModel> Convert(IPager<IFoo> source, IPager<FooModel> destination, ...) {...}

    }

When given a pager, it uses the single object converter implementation anyway.

I know that Automapper will map collections automatically but shouldn't it prefer an explicit collection mapping if one exists? I could probably move the implementations into separate classes but is there another way to get it to use the pager implementation?

Answer 1

You should have called CreateMap and ConvertUsing - did you do this?

cfg.CreateMap<IFoo, FooModel>().ConvertUsing<MyConverter>();
cfg.CreateMap<IPager<IFoo>, IPager<FooModel>>().ConvertUsing<MyConverter>();
