问题 Is there a way to inject dependencies into objects returned from an EF Linq context.Entities.Select(x => new Y {...}) projection? (I am using Simple Injector, but concept remains) Sort of thing I am trying to achieve: (this is just typed in, not compiled, sorry for any syntax errors/incompleteness) // person MAY be an entity, but probably more likely a class to serve a purpose public class Person { public string Name public DateTime DOB {get;set; } // what I want to achieve: note, I don't

问题 I've a small application (for now) that uses translations. My translation Service is called Translator (ITranslator). My problem is that I don't want to retrieve this class in every controller (which returns a view) so I may use it in my views. I've a similar problem with a ListService (where I store all my SelectListItem lists). CustomWebViewPage public abstract class CustomViewPage<TModel> : WebViewPage<TModel> { readonly IScriptFactory scriptFactory; readonly IMembership membership;

问题 My Web Api app is failing when trying to instantiate an injected controller. I'm using Simple Injector. Bootstrapping the injector is as follows: [assembly: WebActivator.PostApplicationStartMethod(typeof(SimpleInjectorWebApiInitializer), "Initialize")] namespace WebApi { using System.Web.Http; using SimpleInjector; using SimpleInjector.Integration.WebApi; public static class SimpleInjectorWebApiInitializer { public static void Initialize() { var container = new Container();

问题 Let's say I have an interface IDependencyResolver: public interface IDependencyResolver{ T Resolve<T>() where T: class; object Resolve(Type source); } And an implementation with the use of SimpleInjector: public class SIDependencyResolver:IDependencyResolver{ private readonly Container _container; public SIDependencyResolver(Container container){ _container = container; _container.Options.DefaultScopedLifestyle = new WcfOperationLifeStyle(); RegisterDependencies(_container, LifeStyle.Scoped);

问题 I have the following (simplified) code. public class Controller { private readonly IService _service; public Controller(IService service) { _service = service; } public async Task<IHttpActionResult> Create(MyObject object) { var result = _service.method(object); if (!result.Succeeded) { return this.GetErrorResult(object); } } } and SimpleInjector is used to inject the dependency between _service and its implementation class, like this: public static void Register(Container container) {

问题 I wanted to inject a logger to my controllers and I needed to pass extended info to the logger's constructor. For the purpose I've use RegisterWithContext : container.RegisterWithContext<Common.Logging.ILogger>(context => { if (context.ServiceType == null && !container.IsVerifying()) { throw new InvalidOperationException( "Can't request ILogger directly from container, " + "it must be injected as a dependency."); } return new Common.Logging.NLogLogger(context.ImplementationType.FullName); });

问题 I am trying to work out how to best inject all of my dependencies into the custom OWIN Middleware I have written for a Web API Application. A simple example would be the DbContext I am using. I have some middleware that needs to potentially query based on the request. The issue I have is that I want my DbContext to otherwise have a WebApiRequestLifestyle scope. My DbContext is registered as such: container.Register<MobileDbContext>(Lifestyle.Scoped); Obviously, this does not work: container

问题 I am working on a small class library and using Simple Injector for my DI. The class library has an access point (some sort of a service I guess) which is public and it has some internal services and repositories. I saw that Simple Injector does not support constructor injection with internal constructors. For example, my product service looks like: internal class ProductService : IProductService { private IProductRepository _productRepository; internal ProductService(IProductRepository

问题 Simple Inject is throwing the following exception when attempting to register my DbContext. The supplied connection string is not valid, because it contains insufficient mapping or metadata information. Parameter name: connectionString I'm new to DI and could be missing something fairly obvious. The connection string looks fine. It is the same one that gets used to create the DbContext normally. I was attempting the solution here public static class SimpleInjectorInitializer { /// <summary

问题 After adding Simple Injector to my project to create an instance of my UserAppManager that will exist through the whole lifetime of a session I started to recieve errors: Error with no parameterless constructor: An error occurred when trying to create a controller of type 'AuthController'. Make sure that the controller has a parameterless public constructor. Error with a parameterless constructor: For the container to be able to create AuthController it should have only one public constructor
