ioc-container

问题 I ran into a problem where I had an Html.DropDownList in my view that would postback the selected value the first time I submitted the form, but each subsequent postback would only post data from the initial postback. So I added lifestyle="transient" to the component element where I had configured my controller for castle windsor, which fixed the problem, but of course made postbacks take longer since a new controller was being instantiated per request. Given the information above, what

问题 we want to use Unity for IOC. All i've seen is the implementation that there is one global static service (let's call it the the IOCService) which holds a reference to the Unity container, which registers all interface/class combinations and every class asks that object: give me an implementation for Ithis or IThat. Frequently i see a response that this pattern is not good because it leads to a dependency from ALL classes to the IOCService (not to the Unity container because it is only known

问题 What I want: Resolve object A, and inside object A, I want use same container to resolve object C: public static void Work() { IUnityContainer con = new UnityContainer(); con.RegisterType<IA, A>(); con.RegisterType<IB, B>(); con.RegisterType<IC, C>(); var a = con.Resolve<IA>(); } interface IA { } interface IB { } interface IC { } class A : IA { public A(IB b, IUnityContainer con) { for (int i = 0; i < 10; i++) { var c = con.Resolve<IC>(); } } } class B : IB { }; class C : IC { }; Problem: On

问题 I am generally a c# developer but working on Java now and then I see a lot of dependency injection using Spring on private properties, with no public way of setting the value. I was surprised this actually works, but I guess it’s possible via reflection? Surely this is terrible practice?! I can't see how anyone unit testing or inspecting the class would possibly know that a private member needs to be set from some external framework. How would you even set the property when you are unit

问题 I'm trying to register a collection along with its instanceCreator. I wasn't able to find any overload for the Container.Collection.Register method which accepts an instanceCreator. If i try to run a loop and register a type along with its instanceCreator multiple times using the Container.Register(instanceCreator, lifestyle) , i'm unable to do it because i get the error that type cannot be registerd multiple times. Basically what i'm trying to do is: foreach(var item in items){ Container

问题 How to manage new tasks with PerRequestLifeTimeManager? Should I create another container inside a new task?(I wouldn't like to change PerRequestLifeTimeManager to PerResolveLifetimeManager/HierarchicalLifetimeManager) [HttpPost] public ActionResult UploadFile(FileUploadViewModel viewModel) { var cts = new CancellationTokenSource(); CancellationToken cancellationToken = cts.Token; Task.Factory.StartNew(() => { // _fileService = DependencyResolver.Current.GetService<IFileService>();

问题 I am building a console .NET Core application. It periodically runs a method that does some work. How do I make ServiceProvider behave in the same way it behaves in ASP.NET Core apps. I want it to resolve scoped services when the method begins it's execution and dispose the resolved services at the end of the method. // pseudocode globalProvider.AddScoped<ExampleService>(); // ... using (var scopedProvider = globalProvider.CreateChildScope()) { var exampleService = scopedProvider.Resolve

问题 I want to use Unity resolve IService to two different implementations, to make use of a wrapper class, the equivalent of: IService service = new DispatcherService(new RealService(), Application.Current.Dispatcher); Where both DispatcherService and RealService implement the IService interface. I have a library containing some services with asynchronous operations. A simplified form of this service looks like this: public interface IService { IAsyncResult StartSomeOperation(); event

问题 I have a manager class that loads various plug-in modules contained in separate assemblies through reflection. This modules are communication to the outside world (WebAPI, various other web protocols). public class Manager { public ILogger Logger; // Modules need to access this. private void LoadAssemblies() { // Load assemblies through reflection. } } These plug-in modules must communicate with an object contained within the manager class. How can I implement this? I thought about using
