.Net 指定时间段内定时执行的Windows服务（System.Threading.Thread）

标签：

1. 创建一个Windows服务项目：解决方案（右击）——> 添加 ——> 新建项目——>项目类型选择Windows——>模板选择Windows服务 ，如图：
   
2. 编写Windows服务程序
   创建后会生成两个文件 Program.cs 和 Service1.cs（我已重命名为MyService.cs），编写服务内容：
   
   具体服务代码：
   
   

    1 using System;
    2 using System.Configuration;
    3 using System.ServiceProcess;
    4 using System.Threading;
    5 
    6 namespace WindowsServiceTest
    7 {
    8     public partial class MyService : ServiceBase
    9     {
   10 
   11         private Thread _thread = null;
   12         private bool serviceIsRun = false;  // 是否一直运行
   13 
   14         public MyService()
   15         {
   16             InitializeComponent();
   17         }
   18 
   19         protected override void OnStart(string[] args)
   20         {
   21             LogHelper.WriteLog("服务启动...");
   22             serviceIsRun = true;
   23             _thread = new Thread(CheckSrv);
   24             _thread.Start();
   25         }
   26 
   27         protected override void OnStop()
   28         {
   29             serviceIsRun = false;
   30             LogHelper.WriteLog("服务停止...");
   31         }
   32 
   33         protected void CheckSrv()
   34         {
   35             var beginTime = ConfigurationManager.AppSettings["BeginTime"];
   36             var endTime = ConfigurationManager.AppSettings["EndTime"];
   37             while (serviceIsRun)
   38             {
   39                 try
   40                 {
   41                     if (IsRunTime(beginTime, endTime))
   42                     {
   43                         // TODO:
   44                         for (int i = 0; i < 10; i++)
   45                         {
   46                             if (!IsRunTime(beginTime, endTime))
   47                             {
