问题 How do I map a property from an object to another object with a different property name? I have a Product class that looks like this: public class Product : IEntity { public int Id { get; set; } public string Name { get; set; } } And the view model looks like: public class ProductSpecificationAddViewModel { public int ProductId { get; set; } public string ProductName { get; set; } } I need to do the following mapping: Product.Id => ProductSpecificationAddViewModel.ProductId Product.Name =

问题 I'm using ValueInjecter instead of AutoMapper. I'm trying to perform unflattening operation using .InjectFrom<UnflatLoopValueInjection>(model) It works, but I would also like to specity some properties to ignore during the unflattening operation, for example writing something like: .InjectFrom<UnflatLoopValueInjection>(new IgnoreProperties("Prop1", "Prop2"), model) or .InjectFrom<UnflatLoopValueInjection>(model).IgnoreProperties("Prop1", "Prop2") Any ideas? 回答1: With the latest version of Omu

问题 in my ASP.NET MVC application I've separated the domain model from the view model. I transform my entity in a viewmodel object so I can "feed" my views with only the data needed (I used valueinjecter for this purpose). During the save process my controller gets back the viewmodel object, transforms it into a domain model entity and try to persist it with SaveOrUpdate. I've noticed that if I try to update an existing record, Nhibernate considers it as a new object and forces an INSERT, even if

问题 Quickly getting to the problem the mapping does not occur for the following code. Could someone explain why? or what i should do for the mapping to occur? var parent = new Parent(); parent.ChildOne.Add(new ChildOne() { Name = "Child One" }); parent.ChildTwo.Add(new ChildTwo() { Name = "Child Two" }); AnotherParent anotherParent = new AnotherParent(); anotherParent.InjectFrom<LoopValueInjection>(parent); Required Class are below Anothher child one public class AnotherChildOne { public string

问题 Given the requirement: Take an object graph, set all enum type properties based on the processed value of a second string property. Convention dictates that the name of the source string property will be that of the enum property with a postfix of "Raw". By processed we mean we'll need to strip specified characters e.t.c. I've looked at custom formatters, value resolvers and type converters, none of which seems like a solution for this? We want to use AutoMapper as opposed to our own

问题 I'm trying to use the ValueInjector (latest version from NuGet) to inject my view model with data from my EntityFramework Code First object. I'll want to do the reverse of this as well, but this is the attempt I'm starting with. I've researched the various mappings and have tried many of them. I haven't found one that does what I need and I think my need is a rather basic one (there are several of these questions on SO and each seems to get a different answer, which is fine.). I've really

问题 When i try to save a Object to EF it throw this exception: An exception of type 'System.InvalidOperationException' occurred in EntityFramework.dll but was not handled in user code. Additional information: Attaching an entity of type 'Sistema.DataEntities.Models.Cliente' failed because another entity of the same type already has the same primary key value. This can happen when using the 'Attach' method or setting the state of an entity to 'Unchanged' or 'Modified' if any entities in the graph

问题 How do I use ValueInjecter with a LINQ join that joins multiple result sets? For example, this code inject result values into CombinedResult object, but I also want some of errorsAndWarning values into CombinedResult . The properties have the same name: var combined = from result in results.DeferredItems join errorsAndWarning in errorsAndWarnings.DeferredItems on result.MeetingID equals errorsAndWarning.MeetingID select new CombinedResult().InjectFrom(result) as CombinedResult; Thanks. 回答1:
