IoC安装和继承类的问题 [英] IoC setup and issue with inherited class

问题描述

我对于IoC模式来说相当新鲜，我遇到了以下问题：

I'm fairly new to the IoC pattern and I've hit an issue on the way the following should be setup.

我有一个服务类它具有以下构造函数：

I've got a Service class which has the following constructor:

public BookingService(IBookingRepository bookingRepository, IUnitRepository   unitRepository, IRateRepository rateRepository, IDiscountRepository discountRepository, IUnitOfWork unitOfWork)
    {
        this.bookingRepository = bookingRepository;
        this.unitRepository = unitRepository;
        this.rateRepository = rateRepository;
        this.discountRepository = discountRepository;
        this.unitOfWork = unitOfWork;
    }

现在我已经有这样使用我的控制器：

Now I've got this working with my controllers like so:

private IBookingService _bookingService;

    public AdminBookingSurfaceController(IBookingService bookingService)
    {
        _bookingService = bookingService;
    }

在我继承的类中使用BookingService时，第三方框架（Umbraco）。

Where I've got stuck is when using the BookingService in an inherited class from a Third Party framework (Umbraco).

这是当前的构造函数：

public class Freedom2BookTree : umbraco.cms.presentation.Trees.BaseTree
{
    public Freedom2BookTree(string application)
        : base(application)
    {
    }

我不知道IoC如何处理这个问题，我试过这样，但没有工作：

I wasn't sure how IoC would work with this, I tried like this but it didn't work:

当我添加附加参数时，构造函数永远不会被命中/调用

As in, when I add the additional parameter the constructor never gets hit/called

public class Freedom2BookTree : umbraco.cms.presentation.Trees.BaseTree
{
    private IBookingService _bookingService;
    public Freedom2BookTree(string application, IBookingService bookingService)
        : base(application)
    {
        _bookingService = bookingService;
    }

如果有人可以借鉴一些建议，我们以错误的方式看待它，那很棒：）

If anyone could lend some advice on how this should be done or if I'm looking at it in the wrong way, that would great :)

很多谢谢，

推荐答案

也许该框架只执行具有特定参数的构造函数。


您可以在 Freedom2BookTree 上指定 IBookingService 它在构造函数之外。

Maybe that framework only executes a constructor with specific parameters.
You can make the IBookingService a property on the Freedom2BookTree and assign it outside of the constructor.
