ninject

问题 Ninject has the functionality of self binding like Bind<Samurai>().ToSelf(); I read about this but I don't get the importance or how this can be useful. Any comments are appreciated. 回答1: If Ninject finds a object that needs to be created and it has a constructor that has a Samurai parameter it does not know how to instantiate it. But when you use Bind<Samurai>().ToSelf(); then Ninject knows that a Samurai needs to be created to pass to the Samurai parameter. If that binding was not there

问题 In Ninject, declaring a binding in singleton scope means that the same object will be returned every time. There can only be one object, ever. What I would like is to return one object at a time. In other words: The first call to Get() instantiates a new object and returns it. Subsequent calls to Get() return the same instance. The object is disposed. The first call to Get() after the object was disposed instantiates a new/second object and returns that. Subsequent calls to Get() return the

问题 My project is structured by services and repositories (all repositories share the db context). In one of my service layers, I have an asynchronous method that writes to the database using a repository. The web request will finish and dispose of the context before this method can get to use it. I tried to understand NamedScopes as stated in this answer. I still can't seem to understand how to implement it. I'll show how my project is structured and hope someone can help me at the code level.

问题 I have an MVC3 application that is using Ninject and MvcSiteMapProvider. I have created this class which MvcSiteMapProvider uses to dynamically add nodes to my sitemap: public class PageNodeProvider : DynamicNodeProviderBase { public override IEnumerable<DynamicNode> GetDynamicNodeCollection() { // need to get repository instance var repository = // how do I get this??? foreach (var item in repository.GetItems()) { yield return MakeDynamicNode(item); } } } The MvcSiteMapProvider instantiates

问题 I am at a loss of what to do with the multitude of documentation available through google in .net as regards using Ninject with asp.net mvc 4 First of all, i want to know if Controller factories are neccessary in asp.net. Also, is constructor injection really the only way we can do dependency injection with MVC 4 because property injection and method injection does not seem to work when i use them with my controllers 回答1: I am not an expert on Ninject but as far as i know, i am only using it

问题 I want to bind multiple implementations of a service and have all of them called at once: var kernel = new StandardKernel(); kernel.Bind<IBreakfast>.To<Spam>(); kernel.Bind<IBreakfast>.To<Eggs>(); kernel.Bind<IBreakfast>.To<MoreSpam>(); kernel.Get<IBreakfast>().Eat(); // call Eat method on all three bound implementations Ninject doesn't like that, and will throw an exception about having multiple bindings. Is there a way I can get around that error, and have all the implementations called?

问题 NInject's module architecture seems useful but I'm worried that it is going to get in a bit of a mess. How do you organise your modules? Which assembly do you keep them in and how do you decide what wirings go in which module? 回答1: Each subsystem gets a module. Of course the definition of what warrants categorisation as a 'subsystem' depends... In some cases, responsibility for some bindings gets pushed up to a higher level as a lower-level subsystem/component is not in a position to make a

问题 I am new to MVC, i am following " PRO ASP.NET MVC 4 by Adam Freeman ". I am currently working on its 6th chapter. In which i am learning how to use Ninject in MVC 4 for Dependency Injection. I have created the application as described in the book. Now i am not getting why the following Error Comes: the type does not appear to implement microsoft.practices.servicelocation.iservicelocator Here is my Controller code: public class HomeController : Controller { private Product[] products = { new

问题 When I have a class with no default constructor, i.e. using dependency injection to pass its dependencies, can Newtonsoft.Json create such an object? For example: public class SomeFoo { private readonly IFooDependency _dependency; public SomeFoo(IFooDependency dependency){ if(dependency == null) throw new ArgumentNullException("dependency"); _dependency = dependency; } public string Data { get; set; } public int MoreData { get; set; } public void DoFoo(){ Data = _dependency.GetFooData();

问题 Have a couple of questions regarding the latest version (2.2.1.4) of ninject. Was trying to Bind a Linq2sql DataContext to a concrete implementation InRequestScope (in a class library project) Bind<DataContext>().To<MoneywatchDataContext>() but could not find InRequestScope method ended up doing this, Bind<DataContext>().To<MoneywatchDataContext>().InScope(ctx => HttpContext.Current) Just wanted to find out if: If this will behave exactly like the InRequestScope Method. That it will gurantee
