全局访问Ninject内核 [英] Accessing the Ninject Kernel Globally

问题描述

这个问题与Ninject没有特别的关系.这更多是一个通用的编码问题，但我将其发布在此处，以防在Ninject中可能有比我尝试做的更好的方法来完全解决该问题.

This question is not specifically related to Ninject. It's more of a general coding question, but I'm posting it here in case there might be a better way entirely of handling the issue in Ninject, than what I am trying to do.

我想知道是否可以从Global.asax中的实例全局访问Ninject标准内核.

I would like to know whether it is possible to access the Ninject Standard Kernel globally, from its instance in Global.asax.

这是代码:

public class MvcApplication : NinjectHttpApplication
{
    protected override void OnApplicationStarted()
    {
        base.OnApplicationStarted();

        // MVC global registration, routing and filtering code goes here...
    }

    protected override IKernel CreateKernel()
    {
        return Container;
    }

    private static IKernel Container
    {
        get
        {
            IKernel kernel = new StandardKernel();
            kernel.Load(new ServiceModule(), new RepositoryModule());
            return kernel;
        }
    }
}

如果我有一些类，例如不与控制器交互的Facade类，我想在其中开始依赖项链，我的理解是我应该使用:

If I have some classes, for example, facade classes that do not interface with the controllers, where I would like to begin a dependency chain, my understanding is I should use:

_className = kernel.Get<IClassName>();

但是，我唯一知道的方法是创建Ninject Standard内核的新实例，但是如果我理解正确的话，创建Ninject内核的新实例不是一个好主意，因为基本上是在创建第二个内核.

However, the only way I know of to do this is to create a new instance of the Ninject Standard kernel, but if I understand correctly, is is not a good idea to create a new instance of the Ninject kernel, because that is basically creating a second kernel.

那么，是否有可能从我的应用程序中的任何位置访问Application Start时已在Global.asax中实例化的现有内核，或者有没有更好的方法可以完全做到这一点?

So, is it possible to access the existing Kernel that was instantiated in Global.asax at Application Start, from anywhere in my application, or is there a better way entirely to do this?

此致

推荐答案

最简单的方法(IMO):

The most simple way (IMO):

_className = (IClassName)System.Web.Mvc.DependencyResolver.Current.GetService(typeof(IClassName));
