public class Source
{
public ChildSource ChildSource { get; set; }
//some other properties
}
public class ChildSource
{
public List<GrandChildSource> GrandChildSources { get; set; }
//some other properties
}
public class GrandChildSource
{
Public ChildSource ChildSource { get; set; }
//some other properties
}
And Dto classes:
public class SourceDto
{
public ChildSourceDto ChildSource { get; set; }
//some other properties
}
public class ChildSourceDto
{
public List<GrandChildSourceDto> GrandChildSources { get; set; }
//some other properties
}
public class GrandChildSourceDto
{
Public ChildSourceDto ChildSource { get; set; }
//some other properties
}
我想将source / childsource类映射到dto类并忽略GrandChildSources属性。
我尝试过使用UseDestinationValue和Ignore,但似乎无法正常工作。
Mapper.CreateMap<Source, SourceDto>()
.ForMember(dest => dest.ChildSource, opt => { opt.UseDestinationValue(); opt.Ignore(); })
.AfterMap((source, destination) => Mapper.Map(source.ChildSource, destination.ChildSource));
Mapper.CreateMap<ChildSource, ChildSourceDto>()
.ForMember(d => d.GrandChildSources, opt => { opt.UseDestinationValue(); opt.Ignore(); });
获取错误“缺少类型映射配置或GrandChildSource不支持的映射”
PS:LazyLoadingEnabled设置为True。我决定在获得Stack溢出异常后忽略GrandChildSources属性,因为它有循环引用。
答案 0 :(得分:1)
除非我遗漏了某些东西,否则这应该是相当简单的直接映射:
Mapper.CreateMap<Source, SourceDto>();
Mapper.CreateMap<ChildSource, ChildSourceDto>()
.ForMember(dest => dest.GrandChildSources, opt => opt.Ignore());
或者,您可以忽略GrandChildSourceDto上的ChildSource
属性,以避免出现循环引用问题。
如果有比这更复杂的事情,请澄清问题所在。
