1.创建WindowsService项目

2.配置项目

3.AddInstaller(添加安装程序)

4.修改ServiceName(服务名称)、StartType(启动类型)、Description(说明)、DisplayName(显示名称)

StartType共有五种类型：Boot(开机启动)、Automatic(自动)、System(系统)、Manual(手动)、Disabled(禁用)

5.选择Account：LocalSystem

Account共有五种：LocalSystem(本地系统)、LocalService(本地服务)、NetworkService(网络服务)、User(用户)

6.编写Timer触发器

using Microsoft.SqlServer.Server;

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Diagnostics;

using System.IO;

using System.Linq;

using System.ServiceProcess;

using System.Text;

using System.Threading.Tasks;

namespace WindowsService_Demo

{

    public partial class WindowServiceDemo : ServiceBase

    {

        private System.Timers.Timer _timer=null;

        public WindowServiceDemo()

        {

            InitializeComponent();

        }

        /// <summary>

        /// 服务启动

        /// </summary>

        /// <param name="args"></param>

        protected override void OnStart(string[] args)

        {

            //实例化定时器 并设置间隔为1秒

            _timer = new System.Timers.Timer();

            //_timer.Interval = 6000; 设置间隔为1秒

            _timer.Start(); //_timer.Enabled=true;

            WriteText("定时服务开始了");

            _timer.Elapsed += Timer_Elapsed;

        }

        private void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)

        {

            WriteText("定时服务正在执行");

        }

        /// <summary>

        /// 服务停止

        /// </summary>

        protected override void OnStop()

        {

            _timer?.Close();

            WriteText("定时服务停止了");

        }

        private static void WriteText(string message)

        {

            string path = AppDomain.CurrentDomain.BaseDirectory + "Log\\";

            string fullPath = path + "log.txt";

            StreamWriter streamWriter=null;

            try

            {

                if (!Directory.Exists(path))

                {

                    Directory.CreateDirectory(path);

                }

                if (!File.Exists(fullPath))

                {

                    streamWriter = File.CreateText(fullPath);

                }

                else

                {

                    streamWriter = File.AppendText(fullPath);

                }

                streamWriter.WriteLine(message +"----------------------"+DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));

            }

            finally

            {

                streamWriter?.Close();

            }

        }

    }

}

7.新建install.bat和uninstall.bat文件(dos下的批处理文件) pause(表示按任意键结束)

install.bat

c:

cd C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319

InstallUtil.exe -i F:\project\dotnet\WindowsService-Demo\WindowsService-Demo\bin\Debug\WindowsService-Demo.exe

net start WindowServiceDemo

sc config WindowServiceDemo start=auto

pause

uninstall.bat

c:

cd C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319

InstallUtil.exe -i F:\project\dotnet\WindowsService-Demo\WindowsService-Demo\bin\Debug\WindowsService-Demo.exe

net start WindowServiceDemo

sc config WindowServiceDemo start=auto

pause
