I'd like to be able to do something like this using automapper:

Mapper.CreateMap<Source, Destination>()
    .ForMember<d => d.Member, "THIS STRING">();

I'd like d.Member to always be "THIS STRING" and not be mapped from any particular member from the source model. Putting a string field in the source model with "THIS STRING" as it's value is also not an option.

Does AutoMapper support these kinds of things in any way?

Mapper.CreateMap<Source, Destination>()
    .ForMember(dest => dest.Member, opt => opt.UseValue<string>("THIS STRING"));

Starting with version 8.0 you have to use the following:

Mapper.CreateMap<Source, Destination>()
    .ForMember(dest => dest.Member, opt => opt.MapFrom(src => "THIS STRING"));
