How can I use AutoMapper for complex object mappings?

AutoMapper is great for mapping complex objects. You can create custom mappings using the CreateMap method.

Can you give me an example of a custom mapping?

MagicBuddy
MagicBuddy

Sure! For instance, if you have a source object with nested properties, you can map them like this: CreateMap<Source, Destination>() .ForMember(dest => dest.NestedProperty, opt => opt.MapFrom(src => src.NestedSource.Property);

What if I need to flatten a complex object?

MagicBuddy
MagicBuddy

You can flatten objects by specifying the destination properties directly in the CreateMap method. Just map each nested property to a flat structure.
