我可以在Castle Windsor中为代理类型定义自定义属性

Question

我有一个类,我用Castle Dynamic Proxy代理它.我想为代理方法添加一些自定义属性(在代理类中没有定义).这可能吗.

我想要这个,因为我想为我的应用程序的服务层生成ASP.NET Web API层.我代理服务(继承自ApiController和其他IMyService接口),它工作得很好,但我想为这个新创建的Dynamic类添加特定于WebAPI的属性,因此Web API框架可以读取它们.

编辑:

如果有人想知道我想要什么,我想详细解释一下.

public interface IMyService
{
    IEnumerable<MyEntity> GetAll();
}

public class MyServiceImpl : IMyService
{
    public IEnumerable<MyEntity> GetAll()
    {
        return new List<MyEntity>(); //TODO: Get from database!
    }
}

public class MyServiceApiController : ApiController,IMyService
{
    private readonly IMyService _myService;

    public MyServiceApiController(IMyService myService)
    {
        _myService = myService;
    }

    public IEnumerable<MyEntity> GetAll()
    {
        return _myService.GetAll();
    }
}

认为我有一个由MyServiceImpl实现的IMyService.我想让一个Api控制器能够从网上使用这项服务.但正如您所见,api控制器只是实际服务的代理.那么,为什么我要写呢？我可以使用城堡windsor动态创建它.

这是我的想法,几乎在我的新项目(https://github.com/hikalkan/aspnetboilerplate)中完成.但是,如果我需要向api控制器的GetAll方法添加一些属性(例如Authorize),该怎么办呢？我不能直接添加,因为没有这样的类,它是城堡动态代理.

所以,除了这个问题.我想知道是否可以向synamic代理类的方法添加属性.

再次查看该项目\n https://github.com/aspnetboilerplate/aspnetboilerplate/issues/55 \n我也想知道如何，以便我可以在 IService 上定义 RoutePrefix 和在 Action 上定义 Route。\n幸运的是，我终于知道如何为代理定义自定义属性。
