Automapper 6.1.1使用MemberList.Source的异常：找到了未映射的成员

Question

我在Automapper中收到以下错误：

Unmapped members were found. Review the types and members below.
Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type
For no matching constructor, add a no-arg ctor, add optional arguments, or map all of the constructor parameters

配置如下所示：

cfg.CreateMap<ArticleViewModel, Article>(MemberList.Source)
    .EqualityComparison((src, dst) => src.Id == dst.Id);

通常情况下，我会像.ForMember(x => x.NoMapProp, opt => opt.Ignore())一样解决它，但由于我正在使用MemberList.Source，因此我无法使用ForMember访问该属性。我该如何解决这个问题？

Answer 1

很简单，就这样解决了：

cfg.CreateMap<ArticleViewModel, Article>(MemberList.Source)
    .EqualityComparison((src, dst) => src.Id == dst.Id)
    .ForSourceMember(x => x.NoMapProp, opt => opt.Ignore());
