Question

有没有办法向构造函数注入一个参数，该参数当前是在basecontroller的Initialize方法中创建的？

示例代码：

public class SSBaseController : Controller
    {
        protected UserProfileClass UserProfile;

        protected override void Initialize(System.Web.Routing.RequestContext requestContext)
        {
            base.Initialize(requestContext);
            UserProfile = UserProfileGetter.getProfileFromDB();
        }

    }

    public class SSController:SSBaseController
    {
        private IProcessService processService;
        public SSController(IProcessService _processService)
        {
            processService = _processService;
        }
    }

    public interface IProcessService
    {
        void doStuff();
    }

    public class ProcessService1 : IProcessService
    {
        private UserProfileClass upc;
        private string _name;
        public ProcessService1(UserProfileClass _profileClass)
        {
            upc = _profileClass;
        }

        public void doStuff()
        {
            _name = upc.name;
            upc.name = "xxx";
        }
    }

    public class UserProfileGetter
    {
        public static UserProfileClass getProfileFromDB()
        {
            return null;
        }
    }

    public class UserProfileClass

    {
        public string name;
    }

另外我想摆脱初始化，这可能吗？如何在SSController中使用该参数注册ProcessService而不是null？

可以集成ASP.NET MVC和Autofaq。您需要做的唯一两件事是注册接口实现并指定Controller的构造函数参数。框架将完成所有其余的工作。见https://code.google.com/p/autofac/wiki/MvcIntegration 这是另外一篇文章：http://blogs.msdn.com/b/roncain/archive/2012/07/16/dependency-injection-with-asp-net-web-api-and-autofac.aspx
