我想知道使用 IOC 容器是否有比下面代码项目示例中建议的方式更优雅的模式。当然，可以使用 IOC 容器，以便当您拥有可靠的 IOC 流程时，控制器构造函数是无参数的。这也意味着当您的应用程序具有比 MVC 更多（例如 WEB-API 和其他任何东西）时，您正在为该技术构建相同类型的解决方案。这对我来说看起来并不干燥。是否有人使用一种很好的模式来“注册”容器，例如 IMyMagicControllerHat 并使用一些不错的 .net 系统库获得单例？很明显，如果你有一个 UI Depends on Core Depends on Model 类型的应用程序，你会关心构建依赖和静态调用。对 MVCApplication 的静态回调与我有关。我一直在寻找更好的方法。

CODEProject 链接.... http://www.codeproject.com/Articles/99361/How-To-Use-Unity-Container-In-ASP-NET-MVC-Framewor

总之相关代码....

public interface IContainerAccessor
{
    IUnityContainer Container { get; }
}
public class MvcApplication : HttpApplication, IContainerAccessor
{
    private static IUnityContainer _container;
    public static IUnityContainer Container
    {
        get { return _container;        }
    }
    public static IUnityContainer Container
    {
        get  {   return _container;    }
    }

还有像 MS 这样的例子，它显示了一个自定义静态作为解决方案。http://msdn.microsoft.com/en-us/library/vstudio/hh323691%28v=vs.100%29.aspx 我期待可能有一个完善的适配器模式或类似模式。我将对统一容器进行 100 次访问，因此正确使用模式看起来很重要。

即使是像这样完全有意义的博客，也没有显示您应该在应用程序中获得对原始容器实例的引用的深度。 http://blog.ploeh.dk/2010/09/29/TheRegisterResolveReleasePattern.aspx

我很欣赏任何关于解决问题的好方法的提示。

那篇 codeproject 文章基于 MVC1 于 2010 年发布。MVC3 现在包含一个 IDependencyResolver 实现，以便更好地与 IoC 集成。对于带有 Unity 的 MVC3，您可以查看Unity.MVC3

如果你想避免构造函数注入，你总是可以将 Unity 注册为默认的 IServiceLocator：

ServiceLocator.SetLocatorProvider(() => new UnityServiceLocator(Container));

如果有人感兴趣，在谷歌搜索期间：我结束了使用自定义全局类。1 静态调用开始事情。其余的作为接口/适配器模式。示例注册 Unity 和企业库。并记录经过身份验证的日志请求的重要细节。 ...这只是部分摘录...用于说明目的

从 MVC 应用程序 Global.asax 调用
