基本控制器类的属性注入
我试图在派生自我的 BaseController 类的任何控制器上自动设置属性。这是我的 Application_Start 方法中的代码。当我尝试访问 UnitOfWork 属性时，它始终为 null。
var builder = new ContainerBuilder();
builder.RegisterControllers(typeof(MvcApplication).Assembly);
builder.RegisterType<VesteraTechnologiesContext>().As<IContext>();
builder.RegisterType<UnitOfWork>().As<IUnitOfWork>();
builder.RegisterType<BaseController>()
.OnActivated(c => c.Instance.UnitOfWork = c.Context.Resolve<IUnitOfWork>());
var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
这是 BaseController 的样子
public class BaseController : Controller
{
public IUnitOfWork UnitOfWork { get; set; }
}
我尝试通过属性而不是通过构造函数来执行此操作的原因是这样我就不必在需要访问 UnitOfWork 的每个控制器中复制构造函数code> 属性，因为构造函数不是继承的。
I'm trying to automatically set a property on any controller that derives from my BaseController class. Here is the code in my Application_Start method. The UnitOfWork property is always null when I try and access it.
var builder = new ContainerBuilder();
builder.RegisterControllers(typeof(MvcApplication).Assembly);
builder.RegisterType<VesteraTechnologiesContext>().As<IContext>();
builder.RegisterType<UnitOfWork>().As<IUnitOfWork>();
builder.RegisterType<BaseController>()
.OnActivated(c => c.Instance.UnitOfWork = c.Context.Resolve<IUnitOfWork>());
var container = builder.Build();
DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
Here is what the BaseController looks like
public class BaseController : Controller
{
public IUnitOfWork UnitOfWork { get; set; }
}
The reason I'm trying to do this via a property instead on through a constructor is so that I don't have to duplicate the constructor in every controller that needs access to the UnitOfWork property, since constructors are not inherited.

Autofac 默认情况下注册控制器以使用构造函数注入。要启用 使用 autofac 进行属性注入：您应该使用:
Autofac by default registers the controllers to use constructor injection. To enable property injection with autofac: you should use:
通常，可以按如下方式调用基本构造函数：
Usually, it's possible to call the base constructor as follows:
