这段程序运用一个sever类设计一个聊天室：
//此类为服务器类-用于与客户端的通信，其中构造了几个自定义事件
using System;using System.Net;
using System.Net.Sockets;
using System.Threading;
namespace sockchat
{
    public delegate void EventServerStartHandler(EventServerStartArgs e);  //声明代理
    public delegate void EventClientContextHandler(EventClientContextArgs e);
    public class EventClientContextArgs //构造自定义事件类
    {
        public string IP;
        public EventClientContextArgs(string _ip)
        {
            IP = _ip;
        }
    }
    public class EventServerStartArgs :EventArgs
    {
        public string returnstring;
        public EventServerStartArgs()
        {
            returnstring = "服务器已启动";
        }
    }
        public class server
        {
            public event EventServerStartHandler SStartEvent;
            public event EventClientContextHandler CcontextEvent;
