I have a entity class that is populated from the backend and then automapper is used to map the data to a new DTO Model. I have other data coming in from another source that has some same data and new data that i want placed into the DTO. When i say same data, I mean, some properties of the new source should overwrite properties in the dto that already have data in them.

Is there a way to use automapper or some nice easy way to merge this data? or is the only way to do this by manual mapping?

Thanks

    I think its not good approach. You should create new DTO everytime when you need modify data. IMHO Composing DTO during life time its bad. – daremachine Oct 13 '17 at 14:45
  • i need to combine the values because a processor that is finally called takes a single model that needs data from multiple sources overwritten in a particular order. – user1161137 Oct 13 '17 at 14:55

You can try something like this: 

var model = Mapper.Map<Model>(dto1);
Mapper.Map(dto2, model);
