C#创建windows服务搭配定时器Timer使用实例（用代码做，截图版）
功能说明：C#创建一个windows服务，服务启动时D:\mcWindowsService.txt写入数据，服务运行期间每隔两秒写入当前时间。原理这些就不说了，三语两语说不清楚，直接贴一个实例。不能贴图片！！那个压缩文里面是word文档！！有图有真相
1．建立空白项目
2.添加创建windows服务需要的引用，选择System.ServiceProcess。
3．创建服务类，继承ServiceBase，类的源代码在后面。
4. 添加windows服务的安装类。
（1）在类名或者解决方案中新建视图：
（2）上一步后会出来类的视图，右键选择查看设计器：
（3）在设计视图里面添加安装器（有可能会弹出警告框，如图，不用管）：
服务创建完成！
安装运行就不用说了吧！！
6 服务类源代码()：
using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Timers;namespace SR171{ class Service17: System.ServiceProcess.ServiceBase { public Service17()//可以自己设定 { this.ServiceName = "MyServiceForShowTime"; this.CanStop = true; this.CanPauseAndContinue = true; this.AutoLog = true; #region 定时器事件 Timer aTimer = new Timer(); //System.Timers，不是form的 aTimer.Elapsed += new ElapsedEventHandler(TimedEvent); aTimer.Interval = 2 * 1000; //配置文件中配置的秒数 aTimer.Enabled = true; #endregion } public static void Main()//必须写 { System.ServiceProcess.ServiceBase.Run(new Service17()); } protected override void OnStart(string[] args)//自己根据要求覆写 { FileStream fs = new FileStream(@"d:\mcWindowsService.txt", FileMode.OpenOrCreate, FileAccess.Write); StreamWriter m_streamWriter = new StreamWriter(fs); m_streamWriter.BaseStream.Seek(0, SeekOrigin.End); m_streamWriter.WriteLine("mcWindowsService: Service Started" + DateTime.Now.ToString() + "\n"); m_streamWriter.Flush(); m_streamWriter.Close(); fs.Close(); } protected override void OnStop() { FileStream fs = new FileStream(@"d:\mcWindowsService.txt", FileMode.OpenOrCreate, FileAccess.Write); StreamWriter m_streamWriter = new StreamWriter(fs); m_streamWriter.BaseStream.Seek(0, SeekOrigin.End); m_streamWriter.WriteLine(" mcWindowsService: Service Stopped " + DateTime.Now.ToString() + "\n"); m_streamWriter.Flush(); m_streamWriter.Close(); fs.Close(); } private static void TimedEvent(object source, ElapsedEventArgs e) //运行期间执行 { FileStream fs = new FileStream(@"d:\mcWindowsService.txt", FileMode.OpenOrCreate, FileAccess.Write); StreamWriter m_streamWriter = new StreamWriter(fs); m_streamWriter.BaseStream.Seek(0, SeekOrigin.End); m_streamWriter.WriteLine("Running.11.. " + DateTime.Now.ToString() + "\n"); m_streamWriter.Flush(); m_streamWriter.Close(); fs.Close(); } }}
