启动start方法即可。
控制线程数量

控制线程的数量可以有效提高系统性能，最简单的方式就是开启一个线程来处理一类业务，将自己的需要处理的加到一个集合中用线程去处理：

                            Service service = new Service();
                            service.Context = context;
                            service.Validator = validator;
                            string key = validator.PlateCode + "." + validator.PlateColor + "." + validator.Channel + "." + validator.DataType;
                            dictionaryService.Add(key, service);
                            dictionaryTime.Add(key, DateTime.Now);

执行业务处理：

        class Service
        {
            public HttpListenerContext Context { set; get; }

            public HttpDataParser.Validator Validator { set; get; }

        }

        /// <summary>
        /// 业务线程执行方法
        /// </summary>
        void ServiceThd()
        {
            while (true)
            {
                try
                {
                    TimeSpan timeSpan;
                    foreach (var item in dictionaryService.ToList())
                    {
                        DateTime startTime;
                        dictionaryTime.TryGetValue(item.Key, out startTime);
                        timeSpan = DateTime.Now - startTime;
                        if (timeSpan.Seconds < 5)
                        {
                            bool flag = ServiceProcess(item.Value.Context, item.Value.Validator);
                            if (flag)
                            {
                                dictionaryService.Remove(item.Key);
                                dictionaryTime.Remove(item.Key);
                            }
                        }
                        else
                        {
                            dictionaryService.Remove(item.Key);
                            dictionaryTime.Remove(item.Key);
                        }
                    }
                    Thread.Sleep(1000);
                }
                catch (Exception ex)
                {
                    SQ.Base.ErrorLog.WriteLog4Ex("上级平台业务处理线程执行GovernmentHttpService:ServiceThd",ex);
                }
            }
        }

        /// <summary>
        /// 执行业务处理方法
        /// </summary>
        /// <param name="context"></param>
        /// <param name="validator"></param>
        bool ServiceProcess(HttpListenerContext context,HttpDataParser.Validator validator)
        {
            try
            {
                string key = validator.PlateCode + "." + validator.PlateColor + "." + validator.Channel + "." + validator.DataType;

                string result = HttpDataParser.GetRedisData(key);

                if (!string.IsNullOrEmpty(result) && result.Contains("@"))
                {
                    SQ.Base.Log.WriteLog4("上级平台业务处理Get data from redis:result=" + result);
                    string[] strs = result.Split('@');

                    var type = strs[0];
                    var json = strs[1];

                    if ("real".Equals(type))
                    {
                        // 实时视频
                        JTSDownRealVideoRequest jtSDownRealVideoRequest = json.ParseJSON<JTSDownRealVideoRequest>();
                        GovernmentWebClientManage.AcceptRealConnect(context, key, validator.Sim, (byte)validator.Channel, (byte)validator.DataType);
                        return true;
                    }
                    else if ("back".Equals(type))
                    {
                        // 回放视频
                        JTRTDownPlayBackMsgStartUp jtRTDownPlayBackMsgStartUp = json.ParseJSON<JTRTDownPlayBackMsgStartUp>();
                        GovernmentWebClientManage.AcceptBackConnect(context, key, validator.Sim, (byte)validator.Channel, jtRTDownPlayBackMsgStartUp.PLAYBACK_STARTTIME.UNIXtoDateTime(), (long)jtRTDownPlayBackMsgStartUp.PLAYBACK_ENDTIME, (AudioVideoFlag)validator.DataType);
                        return true;
                    }
                }
                else
                {
                    SQ.Base.Log.WriteLog4("上级平台业务处理Get data from redis:result="+result);
                }
            }
            catch (Exception ex)
            {
                SQ.Base.ErrorLog.WriteLog4Ex("上级平台业务处理ServiceProcess read data from redis:", ex);
            }
            return false;
        }

这里我们应该注意到，我们会启动这个线程，前面HTTP服务启动中有，代码如下：

                m_service_thread = new Thread(ServiceThd);
                m_service_thread.Name = "ServiceThd";
                m_service_thread.IsBackground = true;
                m_service_thread.Start();

注意：代码的规范性和简洁，才能保证优质的服务。

要记得操作List和Dictionary加锁，以下是示例代码：
