1.新建Windows服務工程，選擇的.NET環境爲.net 4.0

2.雙擊Service查看代碼

3.添加代碼

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.IO;
using System.Timers;

        }

        protected override void OnStart(string[] args)
        {
            //服務開啓執行代碼
            StartDoSomething();
        }

        {
            //服務結束執行代碼
        }
