Do i need to create automapper createmap both ways?

This might be a stupid question! (n00b to AutoMapper and time-short!) I want to use AutoMapper to map from EF4 entities to ViewModel classes. 1) If I call CreateMap<ModelClass, ViewModelClass>() then do I also need to call CreateMap<ViewModelClass, ModelClass>() to perform the reverse? 2) If two classes have the same property names, then do I need a CreateMap statement at all, or is this just for "specific/custom" mappings? In AutoMapper you have a Source type and a Destination type. So you will be able to map between this Source type and Destination type only if you have a corresponding

AutoMapper: How to parse an Int from a String and possible to creating rules based on data type?

I have two models for my form, a ViewModel going to it, and a ControlModel coming from it. The ControlModel has all the same field names and hierarchy, but all of the fields are a string data type. How would you code AutoMapper to convert a string field to integer? I tried Int32.Parse(myString) but Int32 is not available within the expression (gives an error). Mapper.CreateMap<SourceClass, DestinationClass>() .ForMember(dest => dest.myInteger, opt => opt.MapFrom(src => src.myString)); The types in the class and their corresponding conversion types: string to int, int?, double, double?,

Globally apply value resolver with AutoMapper

I'm trying to have AutoMapper take care of localizing all DateTime properties on our view models for us. We use UTC everywhere in our system and store everything in UTC in the database, but we'd like to automatically convert that to a user's time zone for display. After looking at all the options, I settled on using a ValueResolver. Here's the gist of the resolver: public class LocalizedDateTimeFormatter : ValueResolver<DateTime, DateTime> { protected override DateTime ResolveCore(DateTime source) { // get company return company.TimeZone.ConvertFromUtc(source); } } I'm setting up the mapping

问题 I am attempting to test the Index action of a controller. The action uses AutoMapper to map a domain Customer object to a view model TestCustomerForm . While this works I am concerned about the best way to test the results that I am receiving from the Index action. The controller's index action looks like this: public ActionResult Index() { TestCustomerForm cust = Mapper.Map<Customer, TestCustomerForm>(_repository.GetCustomerByLogin(CurrentUserLoginName)); return View(cust); } And its

When using DTOs, Automapper & Nhibernate reflecting changes in child collections of DTO in domain object being updated

阅读更多关于 When using DTOs, Automapper & Nhibernate reflecting changes in child collections of DTO in domain object being updated

I'm not massively familiar with this design but I am hoping to get some guidance. I have a backend service that sends out DTOs to a WPF smart client. On the WPF smart client the user will change,delete and modify items and then the changes are sent back (client --> server). As an example, currently I am working on the Customer details form and the user has the ability to add,remove and change categories belonging to a customer in a datagrid. When the DTO is sent back to the server I would like to load in the domain object that is related to the ID in the DTO and apply the changes made on the

Map async result with automapper

We are createing a Web.Api application of a angularjs application. The Web.Api returns a json result. Step one was getting the data: public List<DataItem>> GetData() { return Mapper.Map<List<DataItem>>(dataRepository.GetData()); } That worked like a charm. Then we made the data repo async and we changed to code to work with it. public List<DataItem>> GetData() { return Mapper.Map<List<DataItem>>(dataRepository.GetDataAsync().Result); } Stil no problems. Now we wanted to make my Web.Api full async awayt so we changed it to: public async Task<List<DataItem>> GetData() { return await Mapper.Map

While I seem to have resolved said changes, I'm not entirely convinced I've done so in the most appropriate way. In the old code, I have a NinjectConfiguration , and an AutoMapperConfiguration class that are each loaded by WebActivator. In the new version the AutoMapperConfiguration drops out and I instead instance a MapperConfiguration directly in the NinjectConfiguration class where the bindings are happening, like so: private static void
