Automapper mapping来自ISource=>IDest的泛型属性,然后指定剩余的映射

我的情况是我必须将相关对象的名称合并到 name 许多不同型号的属性。这些模型的实现需要它们自己的配置。

我试过的是:

ProjectFrom.cs项目

public interface IProjectFrom {
    int Id { get; set; }
}
public class ProjectFromConcreteA : IProjectFrom {
    public int Id { get; set; }
    public string SomeProp { get; set; }
}

ProjectTo.cs项目

public interface IProjectTo {
    string Name { get; set; }
}
public class ProjectToConcreteA : IProjectTo {
    public string Name { get; set; }
    public string SomeProp { get; set; }
}

剖面.cs

CreateMap<IProjectFrom, IProjectTo>()
            .ForMember(projection => projection.Name, expression => expression.ResolveUsing<ProjectionResolver>());
CreateMap<ProjectFromConcreteA, ProjectToConcreteA>()
    .ForMember(concreteTo => concreteTo.SomeProp, expression => expression.MapFrom(concreteFrom => concreteFrom.SomeProp));

项目分解器.cs

public class ProjectionResolver : IValueResolver<IProjectFrom, IProjectTo, string>
{
    private readonly IDependency _dependency;
    public ProjectionResolver(IDependency dependency)
    {
        _dependency = dependency;
    }
    public string Resolve(IProjectFrom source, IProjectTo destination,
        string destMember, ResolutionContext context)
    {
        return _dependency.GetStringFor(source.Id);
    }
}

但是这似乎不起作用,因为我的解析器从来没有使用过。我是不是漏了一步?
