在反射中传递方法参数及注册事件的处理

最近在做一个插件形式的应用组件，用到了一些反射知识，所以写下这边篇文章来让自己以后更好的了解，也希望对一些做类似功能的朋友作参考。

类库代码：

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Reflection;
using System.Text;

namespace Interface
{
    public class Server
    {
        private Socket _serverSocket;
        private byte[] _byteData = new byte[1024];
        public event EventHandler OnReceiveEvent;

        public void Listener()
        {
        try
            {
                _port = ConfigManager.AppSettings["Port"].Value;

                //创建socket，并绑定本地IP、port
                _serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
                //得到本机IP，设置TCP端口号         
                var ip = new IPEndPoint(IPAddress.Any, Convert.ToInt32(_port));
                //绑定网络地址
                _serverSocket.Bind(ip);

                //开始接收client请求
                var sender = new IPEndPoint(IPAddress.Any, 0);
                var remote = (EndPoint)(sender);

                _serverSocket.BeginReceiveFrom(_byteData, 0, _byteData.Length, SocketFlags.None, ref remote, OnReceive, remote);
            }
            catch (Exception ex)
            {
                Log.Error(ex.Message);
            }
        }

        private void OnReceive(IAsyncResult ar)
        {
                string str = "Hello";
                if (OnReceiveEvent != null)
                    OnReceiveEvent(str, null);
        }
}

反射调用方法：

public void Listener()
        {
            try
            {
                //加载程序集(dll文件地址)，使用Assembly类 
                Assembly assembly = Assembly.LoadFile(AppDomain.CurrentDomain.BaseDirectory + "Interface.dll");
                //获取类型，参数（名称空间+类）
                Type type = assembly.GetType("Interface.Server");
                //创建该对象的实例，object类型，参数（名称空间+类
                object instance = assembly.CreateInstance("Interface.Server");
                MethodInfo method = type.GetMethod("Listener"); //方法的名称

                EventInfo eventinfo = type.GetEvent("OnReceiveEvent");
                // 为事件动态绑定处理程序
                if (eventinfo != null)
                    eventinfo.AddEventHandler(instance, new EventHandler(OnReceive));
                method.Invoke(instance, null);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        public void OnReceive(object sender, EventArgs e)
        {
            lbLogs.Items.Add("Server receive: " + sender);
        }
