autofac

问题 I'm trying to figure out how to resolve a instance somewhere in the code. At the application startup I registered a type static void Main() { var builder = new ContainerBuilder(); builder.RegisterType<Foo>().As<IFoo>(); } Now, how can I resolve an instance somewhere in the code ? In StructureMAP there is a static object ObjectFactory.GetInstance<IFoo>() 回答1: Read up on Getting Started. It should get you started. First off, what you are looking for is the container .

问题 let's say this scenario: public class B {}; public class C { public C(B b){} } To resolve C from Autofac container, I have to register both B and C to container. But, today I used Unity, it seems I just need to register B to container, then C can be resolved. So Autofac can't do as Unity do? 回答1: With out-of-the-box Autofac it is expected that every type you want to use is registered with the container, either directly using the Register... methods or in bulk using RegisterAssemblyTypes . But

问题 I'm trying to inject business logic implementations into web API base controller. Somehow property in base controller is always null . Also how can I do lazy injection?

问题 I am new to IoC and am using Autofac in my current project.

问题 I'm still pretty new to using Autofac and one thing I miss in the documentation and examples is how to make it easy to get to the configured container from different places in a web application. I know I can use the Autofac controller factory to automatically resolve constructor injected dependencies for controllers, but how about the other stuff you might need to resolve that is not injected yet. Is there an obvious pattern I am not aware of for this? Thank you! 回答1: First of all try not to

问题 Short Question: Same as this unanswered problem Long Question: I just ported some code over from an MVC 4 + Web Api solution that was using Autofac into my new solution which is also using Autofac but only with Web Api 2 (no MVC 5.1 project, just a web api).

Now I have 2 other projects in the new solution that need to pull a dependency
