C# 耗时统计器（简单）

此处耗时统计实际上采用的是Stopwatch ，因为耗时统计对时间要求比较严苛，

本文所采用方法其实理论上只是用来方便统计、可能准确度上让人不大放心。

本文只是做了个简单的封装、准确度上差别应该不是问题。

调用方法见代码summary

///<summary>耗时统计    ///<para>建议采用关闭时写入、实时写入日志等耗时操作将严重影响统计</para>      ///<para>初始化：string TJGuid = WatchTimerHelper.WatchTimerStart("计时器001")</para>      ///<para>追加消息：WatchTimerHelper.WatchTimerMsgAttach(TJGuid, "预警项目");</para>      ///<para>关闭：WatchTimerHelper.WatchTimerStop(TJGuid);</para>      ///</summary>    public class WatchTimerHelper    {        #region 私有属性        private static Dictionary<string, StopwatchEx> _m_WatchTimerDic = new Dictionary<string, StopwatchEx>();        #endregion        #region 枚举结构        /// <summary>        /// 统计器描述        /// </summary>        public class StopwatchDesc         {            /// <summary>            /// 计时器唯一表示            /// </summary>            public string m_WatchGuid { get; set; }            /// <summary>            /// 计时器名称            /// </summary>            public string m_WatchName { get; set; }            public E_RaiseType m_RaiseType{get;set;}            public E_RaiseTime m_RaiseTime { get; set; }        }        /// <summary>        /// 统计器时间线        /// </summary>        private class StopwatchTimeLine         {            /// <summary>            /// 当前时间点运行总时            /// </summary>            public TimeSpan Elapsed { get; set; }            /// <summary>            /// 当前时间点运行总时 - 毫秒            /// </summary>            public long ElapsedMilliseconds { get; set; }            /// <summary>            /// 当前时间点运行总时 - 秒            /// </summary>            public long ElapsedTicks { get; set; }            public string Msg { get; set; }        }        /// <summary>        /// 统计器        /// </summary>        private class StopwatchEx : Stopwatch        {            public StopwatchDesc m_StopwatchDesc { get; set; }            public List<StopwatchTimeLine> m_RaisTimeLine_List { get; set; }        }        /// <summary>        /// 统计输出类型        /// </summary>        public enum E_RaiseType         {             /// <summary>            /// 控制台            /// </summary>            Console = 0x01,        }        /// <summary>        /// 统计时间输出类型        /// </summary>        public enum E_RaiseTime         {             /// <summary>            /// 实时            /// </summary>            RealTime = 0x01,            /// <summary>            /// 关闭时输出            /// </summary>            StopTime = 0x02,        }        #endregion        #region 公共属性        #endregion        #region 公共方法        /// <summary>        /// 开启耗时统计        /// </summary>        public static string WatchTimerStart(string WatchName,E_RaiseTime RaiseTime = E_RaiseTime.RealTime, E_RaiseType RaiseType = E_RaiseType.Console)        {                       //统计器初始化            StopwatchEx watch = new StopwatchEx();            watch.m_StopwatchDesc = new StopwatchDesc() { m_WatchGuid = Guid.NewGuid().ToString(), m_WatchName = WatchName, m_RaiseTime = RaiseTime, m_RaiseType = RaiseType };            watch.m_RaisTimeLine_List = new List<StopwatchTimeLine>();            _m_WatchTimerDic.Add(watch.m_StopwatchDesc.m_WatchGuid, watch);                         //开始统计            watch.Start();            //附加消息            WatchTimerMsgAttach(watch.m_StopwatchDesc.m_WatchGuid, "统计器开启！");            return watch.m_StopwatchDesc.m_WatchGuid;        }        /// <summary>        /// 关闭耗时统计        /// </summary>        public static void WatchTimerStop(string WatchGuid)        {            if (_m_WatchTimerDic.ContainsKey(WatchGuid) == false)            {                return ;            }            _m_WatchTimerDic[WatchGuid].Stop();            //附加消息 - 输出            WatchTimerMsgAttach(WatchGuid, "统计器结束！");            //去除统计器            _m_WatchTimerDic[WatchGuid] = null;            _m_WatchTimerDic.Remove(WatchGuid);        }        /// <summary>        /// 统计器附加消息        /// </summary>        /// <param name="WatchGuid"></param>        /// <param name="Msg"></param>        public static void WatchTimerMsgAttach(string WatchGuid,string Msg)        {            if (_m_WatchTimerDic.ContainsKey(WatchGuid) == false)            {                return;            }            var watch = _m_WatchTimerDic[WatchGuid];                        StringBuilder SB = new StringBuilder();            //统计器描述            SB.AppendFormat("================================ {0} ================================\r\n",watch.m_StopwatchDesc.m_WatchName);            //标识及时间            SB.AppendFormat("Guid：{0}\tTime：{1}\r\n", watch.m_StopwatchDesc.m_WatchGuid, DateTime.Now.ToString("yyyy-MM-dd"));            //附加消息            SB.AppendFormat("Message：{0}\r\n",Msg);            //时间统计 - 总时秒，总时毫秒，上次总时间            SB.AppendFormat("Times(S)：{0}\tTimes(ms)：{1}\tTimeSpace(ms)：{2}\r\n", watch.ElapsedTicks, watch.ElapsedMilliseconds, watch.m_RaisTimeLine_List.Count > 0 ?
