我的模型对象具有延迟加载集合的一些属性,而AutoMapper用于加载这些集合,即使我不需要它们(这导致我的数据库中有数千个查询执行)。当我调用Mapper.Map
时,是否可以让AutoMapper忽略一些属性?
public TTarget Adapt<TSource, TTarget>(TSource source)
{
return Mapper.Map<TTarget>(source);
}
答案 0 :(得分:4)
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
public class Doctor
{
public int Id { get; set; }
public string Name { get; set;}
}
以下是我如何使用Automapper忽略属性(我已经在源和目标对象中包含了如何忽略它们):
Mapper.CreateMap<Person, Doctor>()
.ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.LastName))
.ForMember(dest => dest.Id, opt => opt.Ignore())
.ForSourceMember(src=> src.FirstName, opt => opt.Ignore());
答案 1 :(得分:2)
Mapper.CreateMap<SourceClass, DestinationClass>()
.ForMember(b=>b.SomeMember, c=>c.Ignore());
答案 2 :(得分:1)
使用AutoMapper 8.0,@ Prabu的答案不再起作用。
8.0 Upgrade Guide - ForSourceMember Ignore
因此调整后的答案将是:
Mapper.CreateMap<Person, Doctor>()
.ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.LastName))
.ForMember(dest => dest.Id, opt => opt.Ignore())
.ForSourceMember(src=> src.FirstName, opt => opt.DoNotValidate());
