利用反射获得委托和事件以及创建委托实例和添加事件处理程序

using System;
using System.Reflection;

namespace ConsoleApplication1
{
   
    public  class Test
    {
        
        public delegate void delegateTest(string s);
        public void method1(string s)
        {
            Console.WriteLine("Create Delegate Instance: " + s);
        }
       
    }

    class Program
    {
        static void Main(string[] args)
        {
            Test test = new Test();
            Type t = Type.GetType("ConsoleApplication1.Test");
            // 因为委托类型编译后是作为类的嵌套类型的，所以这里通过GetNestedType(String s)的方法来获得委托类型。
            Type nestType = t.GetNestedType("delegateTest");

            MethodInfo method =test.GetType().GetMethod("method1",  BindingFlags.Public | BindingFlags.Static|BindingFlags.Instance);
            if (method != null)
            {
                // 创建委托实例
                Delegate method1 = Delegate.CreateDelegate(nestType, test, method);
                //动态调用委托实例
                method1.DynamicInvoke("Hello");
            }

            Console.Read();
        }
    } 
}

using System;
using System.Reflection;

namespace ConsoleApplication2
{
    public class Test
    {
        public event EventHandler TestEvent;
        public void Triggle()
        {
            if (TestEvent != null)
            {
                TestEvent(this, null);
            }
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Test testT=new Test();
            EventInfo eventinfo = typeof(Test).GetEvent("TestEvent");
            if (eventinfo != null)
            {
                // 为事件动态绑定处理程序
                eventinfo.AddEventHandler(testT, new EventHandler(triggleEvent));
                testT.Triggle();
            }
            Console.Read();

        }
        public static void triggleEvent(object sender, EventArgs e)
        {
            Console.WriteLine("Event has been Triggled");
        }
    }
}
