今天写了一段很简单的代码，但一直都有问题。代码如下.

接口定义

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace aoptest

{

   interface ISay

    {

        void Say(string name);

    }

}

实现

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace aoptest

{

    class MySay : ISay

    {

        public void Say(string name)

        {

            Console.WriteLine("fuck off" + name);

        }

    }

}

代理调用

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using Spring.Context.Support;

using Spring.Context;

using Spring.Aop.Framework;

namespace aoptest

{

    class Program

    {

        static void Main(string[] args)

        {

			ProxyFactory factory = new ProxyFactory(new MySay());

			factory.AddAdvice(new MyInterceptor());

			Object o = factory.GetProxy ();

			if (o is ISay) {

				ISay m = o as ISay;

				Console.WriteLine (m.ToString ());

			} else {

				Console.WriteLine ("not my say");

			}

        }

    }

}

这么简单都代码，一直都运行失败，输出“not my say”.

其实很简单，原因就是：

接口应该定义为public的。

这个事情浪费了我两个小时！！！！
