我想在我的代码库中允许声明式 mixin 管理。我想声明一个接口

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，当我执行与引用线程类似的操作时，生成器会抛出一个异常，指出接口在多个地方实现。除了实现自己的拦截器并通过之外，我还能做什么？

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;

    }
}

投掷

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 它更加宽松，它会让 mixin 拥有接口并忽略它作为“附加接口”再次传递。
