Question

我想在我的代码库中允许声明性的mixin管理。我想声明一个像

这样的界面

public interface IMyRepo : IRepository, ICanFindPeopleByName, ICantSing {}

所以我的类只能消耗他们需要的数据访问层的位。在我的IoC容器中，我想将这些接口的实现聚合到一个实例中。但是，当我执行与引用的线程类似的操作时，生成器会抛出一个异常，说明接口是在多个位置实现的。我可以做什么，除了实现我自己的拦截器并通过？

更好的例子（代码墙）

public interface IIceCream {
    void Eat();
}
public class IceCream : IIceCream {
    public void Eat() { Console.WriteLine("Yummy!"); }
}
public interface ICake {
    void NomNom();
}
public class Cake : ICake {
    public void NomNom() { Console.WriteLine("Cakey!"); }
}
public interface ISprinkles {
    void Oogle();
}
public class Sprinkles : ISprinkles {
    public void Oogle(){ Console.WriteLine("Its Pretty!");}
}

public interface IIceCreamWithCakeAndSprinkles : IIceCream, ICake, ISprinkles {}

public class Program
{
    public static void Main()
    {
        var gen = new ProxyGenerator();
        var options = new ProxyGenerationOptions();

        options.AddMixinInstance(new IceCream());
        options.AddMixinInstance(new Cake());
        options.AddMixinInstance(new Sprinkles());

        var result =
            gen.CreateClassProxy(typeof (object), new[] {typeof (IIceCreamWithCakeAndSprinkles)}, options) as IIceCreamWithCakeAndSprinkles;

    }
}

抛出

InvalidMixinConfigurationException: "The mixin IceCream adds the interface 'ConsoleApplication1.IIceCream' to the generated proxy, but the interface already exists in the proxy's additional interfaces. A mixin cannot add an interface already implemented in another way."

更新到动态代理2.2或2.5它更宽松，它会让mixin拥有该接口并忽略它再次作为“附加接口”传递。
