阅读更多关于 Am I using Automapper 2.0's Include functionality correctly?

问题 Either I'm not, or it isn't working... I have a single Source class that I want to map to multiple views that inherit from each other.

Consider this simplified example, using the following domain object: public class Customer { public string Name { get; set; } } I need to map this into a resource object, sort of like a DTO but with added properties to facilitate REST.

This question already has an answer here: Automapper: Update property values without creating a new object 3 answers I don't understand why it's overwriting my whole object. The reason is that I get my User object from db an I want to assign new values from DTO. Instead of just adding those new values it's creating new object that has new values but all previous are set to null . How can I make sure that in this case he will "upgrade" my object, not create new one?

问题 Please see this post for the solution. Ok, I finally figured it out. The: AppDomain.CurrentDomain.GetAssemblies() piece of my code sometimes does not get my mapping assembly so while it is missing I get an error.
