温湿度监控报警程序，设计模式 求指点。
1、程序入口
- C# code
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Data;using System.Data.SqlClient;namespace TemperatureAlarm{ internal class Program { private static void Main(string[] args) { IList<Detectors> detectorList = new List<Detectors>(); using (var db = new LGJKEntities()) { var query = from p in db.Detectors select p; detectorList = query.ToList(); foreach (var item in detectorList) { Detector d = new Detector(item.ID); d.DataChange += (new AlarmCenter()).Alarm; d.DoMonitor(); Console.WriteLine(string.Format("Monitor Start by {0}",item.ID)); } } Console.ReadLine(); } }}2、探头对象，拥有DataChange事件，主要负责监控探头当前各项参数
Detector.cs
- C# code
public class Detector { private int _detectorID = 0; #region 构造函数 public Detector() { } /// <summary> /// 传入探头ID /// </summary> /// <param name="detectorID"></param> public Detector(int detectorID) { this._detectorID = detectorID; } #endregion #region 事件与委托定义 public Action<Object, MonitorEventArgs> DataChange; /// <summary> /// MonitorEventArgs类，用于传递参数 /// </summary> public class MonitorEventArgs : EventArgs { public Detectors info; public MonitorEventArgs(Detectors d) { this.info = d; } } #endregion #region 自定义事件 /// <summary> /// 数据更新 /// </summary> /// <param name="e"></param> protected virtual void OnDataChange(MonitorEventArgs e) { if (DataChange != null) { DataChange(this, e); } } #endregion #region 公共方法 public void DoMonitor() { if (_detectorID > 0) { //开始任务 System.Timers.Timer timer = new System.Timers.Timer(); timer.Interval = 6000; timer.Enabled = true; timer.Elapsed += new ElapsedEventHandler(GetDetectorInfoByID); timer.Start(); } else { Exception ex = new Exception("探头ID不正确"); ExceptionSave.Save("Detector.DoMonitor." + _detectorID.ToString(), ex); } } #endregion #region 私有方法 /// <summary> /// 获取温湿度信息 /// </summary> private void GetDetectorInfoByID(object source, ElapsedEventArgs e) { try { Detectors d = new Detectors(); using (var db = new LGJKEntities()) { d = db.Detectors.First(p => p.ID == _detectorID); } MonitorEventArgs ev = new MonitorEventArgs(d); OnDataChange(ev); } catch (Exception ex) { ExceptionSave.Save("Detector.GetDetectorInfoByID." + _detectorID.ToString(), ex); } } #endregion }3、报警中心，在DataChange事件触发时，交由此类中的Alarm进行处理，负责判断当前传入的探头参数是否应该触发警报，并根据警报开关进行选择性报警。
- C# code
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace TemperatureAlarm{ public class AlarmCenter { public void Alarm(Object sender, Detector.MonitorEventArgs e) { Detectors d = e.info; //总开关 if (d.AlarmSP == "关") { return; } TAlarm(d); HAlarm(d); } /// <summary> /// 湿度报警判断 /// </summary> /// <param name="d"></param> private void HAlarm(Detectors d) { AlarmInfo alarmInfo = new AlarmInfo(Common.FormatDouble(d.Humidity), Common.FormatDouble(d.MinHumidity), Common.FormatDouble(d.MaxHumidity), d.HumidityAlarm, d.HumidityCondition); if (alarmInfo.IsAlarm) { //短信报警 if (d.SMSAlarm == "开") { SMSAlarm sms = new SMSAlarm(); sms.DoAlarm(); } //设备报警 if (d.DeviceAlarm == "开") { DeviceAlarm device = new DeviceAlarm(); device.DoAlarm(); } //服务器报警 if (d.ServerAlarm == "开") { ServerAlarm server = new ServerAlarm(); server.DoAlarm(); } } } /// <summary> /// 温度报警判断 /// </summary> /// <param name="d"></param> private void TAlarm(Detectors d) { AlarmInfo alarmInfo = new AlarmInfo(Common.FormatDouble(d.Temperature), Common.FormatDouble(d.MinTemperature), Common.FormatDouble(d.MaxTemperature), d.TemperatureAlarm, d.TemperatureCondition); if (alarmInfo.IsAlarm) { //短信报警 if (d.SMSAlarm == "开") { SMSAlarm sms = new SMSAlarm(); sms.DoAlarm(); } //设备报警 if (d.DeviceAlarm == "开") { DeviceAlarm device = new DeviceAlarm(); device.DoAlarm(); } //服务器报警 if (d.ServerAlarm == "开") { ServerAlarm server = new ServerAlarm(); server.DoAlarm(); } } } } /// <summary> /// 短信报警 /// </summary> public class SMSAlarm { public void DoAlarm() { } } /// <summary> /// 设备上的警号报警 /// </summary> public class DeviceAlarm { public void DoAlarm() { } } /// <summary> /// 服务器上的警号报警 /// </summary> public class ServerAlarm { public void DoAlarm() { } }}
4、报警信息，判断报警信息是否达到报警条件
- C# code
using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace TemperatureAlarm{ /// <summary> /// 警报类：负责判断传入的参数是否触发警报 /// </summary> public class AlarmInfo { public double MaxValue; public double MinValue; public double Value; public string AlarmSwitch; public string AlarmCondition; public int AlarmCode; public bool IsAlarm; public AlarmInfo() { } public AlarmInfo(double _val, double _min, double _max, string _switch, string _condition) { this.MaxValue = _max; this.MinValue = _min; this.Value = _val; this.AlarmSwitch = _switch; this.AlarmCondition = _condition; this.AlarmCode = GetAlarmCode(); this.IsAlarm = CheckAlarm(); } /// <summary> /// 判断是否需要报警 /// </summary> /// <param name="alarmInfo"></param> /// <returns></returns> private bool CheckAlarm() { int iConditionValue = 0; if (this.AlarmSwitch == "开") { switch (this.AlarmCondition) { case "上下都报": iConditionValue = 3; break; case "上报": iConditionValue = 2; break; case "下报": iConditionValue = 1; break; case "不报": iConditionValue = 0; break; default: iConditionValue = 3; break; } } return ((this.AlarmCode & iConditionValue) > 0); } /// <summary> /// 计算报警代码：11，10，01 /// 分别代表：上下都报，上报，下报 /// </summary> /// <returns></returns> private int GetAlarmCode() { int intAlarmCode = 0; intAlarmCode += CalcValue(this.Value, this.MaxValue, 2); intAlarmCode += CalcValue(this.MinValue, this.Value, 1); return intAlarmCode; } /// <summary> /// 当前者大于后者时，返回累加值 /// </summary> /// <param name="firstNum"></param> /// <param name="secondNum"></param> /// <param name="plusValue"></param> /// <returns></returns> private int CalcValue(double firstNum, double secondNum, int plusValue) { if (firstNum <= secondNum) { plusValue = 0; } return plusValue; } }}5、疑问，主要在报警器选择这个地方，觉得代码只是能完成任务，但不够优雅，无论是简单工厂模式、策略模式还是工厂方法模式都是多选一。。小弟初学设计模式，希望能得到前辈们的指点，谢谢。
如有其他不正之处也请一一指出，小弟感激不尽。。

这个典型的用观察者来做吧？

这当然，设计模式本身也没有“让代码优雅”的功能。你要把代码写优雅，就要先把C#语言学好。

楼主的代码问题很多。确定关闭的时候程序没有异常？？？
