问题 I Have a custom HandleErrorAttribute that extends FilterAttribute . How can I have Unity inject dependencies into this attribute at the same time that it injects the controller's dependencies itself? 回答1: Ok, figured it out. Mostly I used Ben's solution above from the blog post he pointed to. The problem is that Unity behaves a little differently. You can't inject dependencies on the filters directly, because they are of type IActionFilter and IExceptionFilter respectively. This led me to

问题 Using Unity Application block how can you force the Unity configuration to create a new instance of an object when we call the UnityContainer.Resolve<T>() method in WCF context? 回答1: Lifetime Manager in Unity is all what you need. By default, Unity use TransientLifetimeManager : TransientLifetimeManager. For this lifetime manager Unity creates and returns a new instance of the requested type for each call to the Resolve or ResolveAll method. This lifetime manager is used by default for all

问题 I have the following scenario : public interface IFoo { } public interface IFoo3 { } public class Foo4 : IFoo3 { } public class Foo1 : IFoo { } public class Foo2 : IFoo { Foo2 (IFoo object1, IFoo3 object2) } on the client side : IUnityContainer container = new UnityContainer(); container.RegisterType<IFoo, Foo1>("Foo1"); container.RegisterType<IFoo3, Foo4>(); container.RegisterType<IFoo, Foo2>("Foo2"); IFoo3 obj = container.Resolve<IFoo3>(); //Resolve 1 IFoo obj2 = container.Resolve<IFoo>();

问题 I use Microsoft Unity as IoC container and wrote some code like this: public static void RegisterTypes(IUnityContainer container) { MyContext ctx = new MyContext (); // is EntityFramework DbContext container.RegisterType(typeof(IEntityRepository<>), typeof(EntityRepository<>), new InjectionConstructor(ctx)); container.RegisterType(typeof(IEntityService<>), typeof(EntityService<>)); } It works for me without problem, but I want to know how to write its equivalent in SimpleInjector . 回答1: There

问题 2 months ago I have asked about this problem! and the problem still exists. I am not going to copy/paste the same problem here because I found out that the error is not for a specific Entity-DTO mapping but for any Entity-DTO which is first in a controller. I mean if the program flow hits to a Country-CountryDto, the error says: Missing type map configuration or unsupported mapping. Mapping types: Country -> CountryDTO MyApp.Domain.BoundedContext.Country -> MyApp.Application.BoundedContext

问题 I have these constructors: public Configurator(string workingDirectory, string siteExclusions) : this(directory, exclusions, new ServerManager(), new DirectoryCheck()) { } public Configurator(string directory, string exclusions, IServerManager manager, IDirectoryCheck directoryCheck) { this.manager = manager; this.directoryCheck = directoryCheck; if (exclusions != null) { // do stuff } this.directory = directory; } Where directory and exclusions are created by the creating code, within a

问题 I am struggling with this problem of dependency injection using untiy . I have implemented according to this link https://www.asp.net/web-api/overview/advanced/dependency-injection But got this error: { "Message": "An error has occurred.", "ExceptionMessage": "An error occurred when trying to create a controller of type 'WebAPIController'. Make sure that the controller has a parameterless public constructor.", "ExceptionType": "System.InvalidOperationException", "StackTrace": " at System.Web

问题 Disclaimer: I have a fair bit of experience with DI containers but am quite new to Unity. I have an MVC project that is all wired up with Unity DI using constructor injection and works great. But I now have a service that I want to inject into my controllers (and maybe places other than controllers at some point) and this service needs access to ASP.NET session state. The service's purpose is to manage a list in session and I don't want the list mechanics in my controller. I realize I could

问题 I've just revisited some very old code to update it to the latest version of Prism (Version 5) and during Module initialisation I was getting the following exception message: Exception is: InvalidOperationException - To use the UIThread option for subscribing, the EventAggregator must be constructed on the UI thread. Wherever I was executing something like: eventAggregator.GetEvent<AppStatusMessageEvent>() .Subscribe(OnAppStatusChanged, ThreadOption.UIThread, true); Changing all of these

问题 I am using ASP.NET MVC 5 with Unity 3 and Unity bootstrapper for ASP.NET MVC. In the UnityConfig.cs file, I registered the following type in the RegisterTypes method: public static void RegisterTypes(IUnityContainer container) { container.RegisterType<IProjectRepository, ProjectRepository>(); } In an MVC controller, I am resolving like this: UnityContainer container = new UnityContainer(); public ActionResult List() { var projectRepository = container.Resolve<IProjectRepository>(); return
