这是一个调用sharpsocket类库的例子。这个库用起来很简单，性能稳定快速，支持tcp和udp收发任意数据，我之前项目里用过。这里分享下demo。

using System;
using System.Windows.Forms;
using System.Net;
using CoreDll;
using SharpSocket;
using SharpSocket.Interface;

namespace UDPServer
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();            
        }

        #region 变量
        private IUdp udpServerInstance = null;

        #region UI事件

        {
            #region 设置授权,试用版直接使用Test即可。正式授权请访问http://sharpsocket.zzsgzn.com
            KeyMgr.SetKey("Test", "Test");

        }

            {
                //创建一个接口实例，然后就可以操作它了
                udpServerInstance = SocketFactory.GetUdp();

                //设置本端使用的端口号
                udpServerInstance.Port = int.Parse(this.edtPort.Text);

                //订阅本接口的收到数据的事件通知，当收到数据后，自动回调您注册的方法

                //启动即可
                udpServerInstance.Initialize();
