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.Collections.Generic;
using System.IO;
using System.Linq;

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);

            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();
        }

    }
}
