Question

如何使用Ninject更改要注入的Concrete类。到目前为止，我为每个具体类都有一个接口。我现在有一个单独的接口的两个具体类，其中一个需要根据我正在注入的属性/控制器被选择。

class IService {}

class ConcreteServiceA : IService {}

class ConcreteServiceB : IService {}

// Where the binding happens-
private static void RegisterServices(IKernel kernel)
{
    kernel.Bind<IService>().To<ConcreteServiceA>();
    kernel.Bind<IService>().To<ConcreteServiceB>();
}

class ControllerA {
    [Inject]
    // Needs to be ConcreteServiceA
    public IService _service { get; set; }
}

class ControllerB {
    [Inject]
    // Needs to be ConcreteServiceB
    public IService _service { get; set; }
}

您可以在NInject Method WhenInjectedInto

之后尝试此操作

Bind<IService>().To<ConcreteServiceA>().WhenInjectedInto(typeof(ControllerA));
Bind<IService>().To<ConcreteServiceB>().WhenInjectedInto(typeof(ControllerB));

Ninject：更改控制器的混凝土类别？
