创建一个简单的windows服务，每间隔一定时间重复执行批处理文件

public class BusinessLogic
{
    System.Timers.Timer timer;
    String autoBat = System.Configuration.ConfigurationManager.AppSettings["AutoBatPosition"]; //批处理文件的路径       
        public static NLog.Logger log = NLog.LogManager.GetCurrentClassLogger();//执行间隔

    public void Run()
    {
        int intervalSecond = int.Parse(System.Configuration.ConfigurationManager.AppSettings["IntervalSecond"]);
        timer = new System.Timers.Timer(intervalSecond * 1000); //间隔秒
        timer.AutoReset = true;
        timer.Enabled = true;  //一直执行
        timer.Elapsed += new ElapsedEventHandler(DoMerger);
        timer.Start(); 
    }

    //调用批处理
    private void DoMerger(object source, System.Timers.ElapsedEventArgs e)
    {
        try
        {
            log.Info("开始");

            log.Info("执行批处理开始");
            System.Diagnostics.Process process = new System.Diagnostics.Process();
            process.StartInfo.FileName = autoBat;
            process.StartInfo.UseShellExecute = false; //此处必须为false否则引发异常
            process.Start();
            process.WaitForExit();
            log.Info("执行批处理结束");
            log.Info("结束");
        }
        catch (Exception ex)
        {
            log.Error(ex.ToString());
        }
    }

    public void Stop()
    {
        timer.Close();
    }
}

public partial class Service1 : ServiceBase
{
    BusinessLogic logic = null;
    public Service1()
    {
        InitializeComponent();
        logic = new BusinessLogic();
    }

    protected override void OnStart(string[] args)
    {
        logic.Run();
    }
　　　　
    protected override void OnStop()
    {
        logic.Stop();
    }
}
