Question

是否可以用与what can be done with Web API类似的方式为在简单注入器中注册的Mvc控制器注册自定义IHttpControllerActivator？

我运行DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));时，也会将简单的注射器插入我的第三方控制器中，这是我想避免的。

根据史蒂文在评论中的建议，我提出了以下建议：

public class MvcControllerFactory : DefaultControllerFactory
{
    private readonly Container _container;
    private readonly IControllerFactory _original;

    public MvcControllerFactory(
        Container container, IControllerFactory original)
    {
        _container = container;
        _original = original;
    }

    protected override IController GetControllerInstance(
        RequestContext requestContext, Type controllerType)
    {
        if (controllerType == null)
        {
            return null;
        }

        if (controllerType == typeof(MyMvcController))
        {
            return (IController)_container.GetInstance(controllerType);
        }

        var controllerName = requestContext.RouteData.GetRequiredString("controller");
        if (!string.IsNullOrEmpty(controllerName))
        {
            return _original.CreateController(requestContext, controllerName);
        }

        return (IController) Activator.CreateInstance(controllerType);
    }
}

在我的应用程序开始：

var original = ControllerBuilder.Current.GetControllerFactory();
var controllerFactory = new MvcControllerFactory(container, original);
ControllerBuilder.Current.SetControllerFactory(controllerFactory);

自定义IHttpControllerActivator用于MvcControllers
