Let's assume that I've two classes : CD and CDModel, and the mapping is defined as follows:
Mapper.CreateMap<CDModel, CD>()
.ForMember(c => c.Name, opt => opt.MapFrom(m => m.Title));
Is there an easy way to retrieve the original expression like c => c.Name (for source) and m => m.Title (for destination) from the mapping?
I tried this, but I miss some things...
var map = Mapper.FindTypeMapFor<CDModel, CD>();
foreach (var propertMap in map.GetPropertyMaps())
{
var source = ???;
var dest = propertMap.DestinationProperty.MemberInfo;
}
How to get the source and destination expressions?

Once you have your types, and a reference to AutoMapper, you can create a map for the two types. Mapper. CreateMap<Order, OrderDto>(); The type on the left is the source type, and the type on the right is the destination type.
Polymorphic element types in collectionsAutoMapper supports polymorphic arrays and collections, such that derived source/destination types are used if found.
By default, AutoMapper only recognizes public members. It can map to private setters, but will skip internal/private methods and properties if the entire property is private/internal.
Going along the same path as what you were doing ...
foreach( var propertMap in map.GetPropertyMaps() )
{
var dest = propertMap.DestinationProperty.MemberInfo;
var source = propertMap.SourceMember;
}
How exactly do you want the expressions? Are you wanting the underlying Lambas?
If so look at
propertMap.GetSourceValueResolvers()
