Is it possible to map multiple DTO objects to a single ViewModel using Automapper?
Check for following link regarding your query
You could create a composite DTO that holds two or more DTO objects and map the composite DTO to the output view model.
If you have 2 DTO classes and 1 flattened view model:
public class Dto1{ public string Property1 { get; set; }}public class Dto2{ public string Property2 { get; set; }}public class FlattenedViewModel{ public string Property1 { get; set; } public string Property2 { get; set; }}And you create mappings for both DTOs to view model:
CreateMap<Dto1, FlattenedViewModel>();CreateMap<Dto2, FlattenedViewModel>();You can map 1st DTO to the model and then just "append" 2nd DTO:
var dto1 = new Dto1 { Property1 = "Value1"; }var dto2 = new Dto2 { Property2 = "Value2"; }var model = Mapper.Map<FlattenedViewModel>(dto1); // map dto1 propertiesMapper.Map(dto2, model); // append dto2 properties
