automapper - Automapper (v5.1) ConstructedBy 替换？

Question

我刚刚将我的 Automapper 从 4.1 升级到 5.1，我发现 ConstructedBy 似乎不再是一个有效的功能。我阅读了帮助文件，它仍然将 ConstructedBy 引用为有效。

代码如下所示：

cfg.CreateMap<XElement, Article>()
        .ForMember(
            dest => dest.Publication,
            opt => opt.ResolveUsing<XAttributeResolver<string>>()
                      .ConstructedBy(() => new XAttributeResolver<string>("publication_name", "publication", "publications")));

Answer 1

直接构造解析器即可。我删除了冗余配置以支持重载：

cfg.CreateMap<XElement, Article>()
    .ForMember(
        dest => dest.Publication,
        opt => opt.ResolveUsing(new XAttributeResolver<string>("publication_name", "publication", "publications")));
