Automapper-它是否映射对象列表? [英] Automapper - Does it map lists of objects?

问题描述

我有以下自动映射器定义:

I have the following Automapper defintion:

Mapper.CreateMap<IB.BusinessComponents.Data.LocationMaster, IB.Entites.Master.Location>();
Mapper.CreateMap<IB.BusinessComponents.Data.LocationMaster, IB.Entites.Master.Location>()
    .ForMember(destination => destination.Id, source => source.MapFrom(item => item.LocationMasterID))
    .ForMember(destination => destination.ChildLocationList, source => source.Ignore());

当我映射单个对象时，这可以正常工作.但是我似乎无法传递对象列表.传递列表时是否需要其他定义，还是不可能?

This works fine when I map a single object. But I can't seem to pass in Lists of objects. Do I need a different definition when passing in a list, or is it not possible?

推荐答案

在您的AutoMapper定义中:

In your AutoMapper Definition:

    CreateMap<MyStuffDTO, MyStuffViewModel>()
        .ForMember(dto => dto.MyDate, opt => opt.MapFrom(src => src.LastDate))
        .ForMember(dto => dto.MyTime, opt => opt.MapFrom(src => src.LastTime))
        .ForMember(dto => dto.Category, opt => opt.MapFrom(src => src.Category));

在代码中:

单身:

var result = Mapper.Map<MyStuffDTO, MyStuffViewModel>(obj);

对于列表:

var list = Mapper.Map<IList<MyStuffDTO>, IList<MyStuffViewModel>>(obj);
