通过 ForMember 从自定义地图中提取 AutoMapper 源名称

我已使用以下代码成功从现有 Automapper TypeMap 中提取了简单的源/目标对：

private MemberInfo getSource(Type destinationType, string destinationPropertyname)
{
  TypeMap map = Mapper.GetAllTypeMaps()
                      .Where(m => m.DestinationType.Equals(destinationType))
                      .First();
  IEnumerable<PropertyMap> properties = 
      map.GetPropertyMaps()
         .Where(p => p.DestinationProperty
                      .Name
                      .Equals(destinationPropertyname, 
                              StringComparison.CurrentCultureIgnoreCase));
  PropertyMap sourceProperty = properties.First();
  IMemberGetter mg = sourceProperty.GetSourceValueResolvers()
                                   .Cast<IMemberGetter>()
                                   .First();

  return mg.MemberInfo;
}

但是，当我添加如下所示的自定义列映射时：

Mapper.CreateMap<Customer, CustomerViewModel>()
      .ForMember(dest => dest.Cell, opt => opt.MapFrom(src => src.CellPhone))
      .ForMember(dest => dest.Email, opt => opt.MapFrom(src => src.EmailAddress));

...映射的源部分无法从 GetSourceResolvers()我可以告诉。

我很感激你的任何指导。

谢谢。

I have successfully extracted simple source/destination pairs from an existing Automapper TypeMap using this code:

private MemberInfo getSource(Type destinationType, string destinationPropertyname)
{
  TypeMap map = Mapper.GetAllTypeMaps()
                      .Where(m => m.DestinationType.Equals(destinationType))
                      .First();
  IEnumerable<PropertyMap> properties = 
      map.GetPropertyMaps()
         .Where(p => p.DestinationProperty
                      .Name
                      .Equals(destinationPropertyname, 
                              StringComparison.CurrentCultureIgnoreCase));
  PropertyMap sourceProperty = properties.First();
  IMemberGetter mg = sourceProperty.GetSourceValueResolvers()
                                   .Cast<IMemberGetter>()
                                   .First();

  return mg.MemberInfo;
}

However, when I add custom column mappings like this:

Mapper.CreateMap<Customer, CustomerViewModel>()
      .ForMember(dest => dest.Cell, opt => opt.MapFrom(src => src.CellPhone))
      .ForMember(dest => dest.Email, opt => opt.MapFrom(src => src.EmailAddress));

... the source part of the mapping is not available from GetSourceResolvers() that I can tell.

I appreciate any guidance you have.

Thank you.

这符合你想要的吗？

var map = Mapper.FindTypeMapFor<Customer, CustomerViewModel>();

foreach( var propertMap in map.GetPropertyMaps() )
{
    var dest = propertMap.DestinationProperty.MemberInfo;
    var source = propertMap.SourceMember;
}

Is this along the lines of what you wanted?

var map = Mapper.FindTypeMapFor<Customer, CustomerViewModel>();

foreach( var propertMap in map.GetPropertyMaps() )
{
    var dest = propertMap.DestinationProperty.MemberInfo;
    var source = propertMap.SourceMember;
}
