Quartz.Net系列（十一）：System.Timers.Timer+WindowsService实现定时任务

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(6000);

            //_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
