由 做~自己de王妃 提交于 2019-11-26 21:28:34
问题 I am trying to Bind two concrete classes to one interface. What command should I use in Ninject to do that? What I am trying to do is to Bind two concrete classes to one interface base on the controller Name. Is that possible? I suppose that in ninject you use the .When to give the conditional but there is no tutorial out there where they show you how to use the .When for ninject. 回答1: Here are few examples. Check out Ninject source project and its Tests subproject for various samples of

问题 In MVC I simply make the class NinjectControllerFactory that implements DefaultControllerFactory interface then do some bindings in it. at last in Global I run it: ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory()); But what about using Ninject in ASP.NET Web API? there are some information on the web but are out dated and for pre-released versions. Is there a straightforward way for this problem? 回答1: The reason a lot of the articles are old is because the

问题 I was surprised to find that at least one of my objects created by Ninject is not disposed of at the end of the request, when it has been defined to be InRequestScope Here's the object I'm trying to dispose: Interface: public interface IDataContext : IDisposable { MessengerEntities context { get; set; } } MessengerEntities is Entity Framework's implementation of ObjectContext -- my context object. Then I create a concrete class like so: public class DataContext : IDataContext { private

Does Ninject support Func (auto generated factory)?

由 我的梦境 提交于 2019-11-26 17:35:07
Autofac automatically generates factories for Func<T> ; I can even pass parameters. public class MyClass { public MyClass(Func<A> a, Func<int, B> b) { var _a = a(); var _b = b(1); } } Can I do the same with Ninject? If not, what workaround can I apply? Thanks. Update : Just found this post, seems the answer is no: How do I handle classes with static methods with Ninject? Remo Gloor NB Ninject 3.0 and later has this fully supported using the Ninject.Extensions.Factory package, see the wiki:- https://github.com/ninject/ninject.extensions.factory/wiki EDIT: NB there is a Bind<T>().ToFactory()

问题 I read as many answers as I could for this, but they seem to fall short of one detail. The trouble is when binding an action filter (with a service injected by controller) to a corresponding attribute, I've been unable to figure out how to pass parameter/property values from the attribute to its bound filter. Below is the code, and below that my intended fake-code: Filter & Attribute public class AuthorizationFilter : IAuthorizationFilter { private readonly IAuthorizationService

Parameterless constructor error with Ninject bindings in .NET Web Api 2.1

由 徘徊边缘 提交于 2019-11-26 16:41:40
问题 Working currently on writing an API site (.NET Web Api 2.1) For our prior API sites we had used the Ninject.MVC3 package and wired up a dependency resolver and scope manually and plugged in our logic into NinjectWebCommon as per the recommendation. This was causing heartburn int our new project with the parameterless constructor error. In the past, this was a dead give away that we were not wiring up the dependency resolver in Web Api properly. Only this time, we were. It was there. var

问题 I have the following (simplified) situation: I have two interfaces interface IAmAnInterface { void DoSomething(); } and interface IAmAnInterfaceToo { void DoSomethingElse(); } and a class implementing both: class IAmAnImplementation: IAmAnInterface, IAmAnInterfaceToo { public IAmAnImplementation() { } public void DoSomething() { } public void DoSomethingElse() { } } Now I bind the same class to both interfaces using Ninject. Since I want the same instance of IAmAnImplementation beeing used

I decided to start using Ninject and face an issue. Say I have the following scenario. I have an IService interface and 2 classes implementing this interface. And also I have a class, which has a constructor getting IService and an int .

Here's some code illustrating the situation: interface IService { void Func(); } class StandardService : IService { public void Func() { Console.WriteLine("Standard"); } } class AlternativeService : IService { public void
