C# 反射 怎么监听事件?

        static void Main(string[] args)

        {

            string path = @"D:\lassLibrary1Demo.dll";

            Assembly ass = Assembly.LoadFile(path);      //获取DLL的集合

            Type tp = ass.GetType("lassLibrary1Demo.Sample1");                      //获得DLL中的指定类型

            object tmpobj = ass.CreateInstance("lassLibrary1Demo.Sample1");         //获得DLL中指定类的实例

            //这里如何对DLL中的事件进行监听呢？

            Console.Read();

        }

    public class Sample1

    {

        public delegate bool ReturnBoolHandler(string info);

        public delegate void TestHandler(string msg);

        public ReturnBoolHandler ReturnBoolEvent;

        public TestHandler TestEvent;



        /// <summary>

        /// 显示

        /// </summary>

        /// <param name="s"></param>

        /// <returns></returns>

        public string Display()

        {

            if (ReturnBoolEvent != null)

                ReturnBoolEvent("触发了返回bool值的事件");

            if(TestEvent != null)

                TestEvent("触发了无返回类型的事件");

            return "无参数方法";

        }

    }
