Windows服务在特定分钟内每小时运行一次

Question

我需要帮助.我有Windows服务,我需要在特定时间每小时运行一次这项服务,例如:09:05,10:05,11:05,....我的服务现在每小时开始,但从我开始这项服务的每个小时开始.那么我怎样才能实现我的需求呢.

我的代码:

public partial class Service1 : ServiceBase
{
    System.Timers.Timer timer = new System.Timers.Timer();

    public Service1()
    {
        InitializeComponent();
    }

    protected override void OnStart(string[] args)
    {
        this.WriteToFile("Starting Service {0}");

        timer.Elapsed += new ElapsedEventHandler(OnElapsedTime);

        timer.Interval = 60000;

        timer.Enabled = true;
    }

    protected override void OnStop()
    {
        timer.Enabled = false;

        this.WriteToFile("Stopping Service {0}");
    }

    private void OnElapsedTime(object source, ElapsedEventArgs e)
    {
        this.WriteToFile(" interval start {0}");
    } }

您应该从计时器每隔'n'秒(例如1)检查当前时间:

public partial class Service1 : ServiceBase
{
    System.Timers.Timer timer = new System.Timers.Timer();

    public Service1()
    {
        InitializeComponent();
    }

    protected override void OnStart(string[] args)
    {
        this.WriteToFile("Starting Service {0}");

        timer.Elapsed += new ElapsedEventHandler(OnElapsedTime);

        timer.Interval = 1000; // 1000 ms => 1 second

        timer.Enabled = true;
    }

    protected override void OnStop()
    {
        timer.Enabled = false;

        this.WriteToFile("Stopping Service {0}");
    }

    private int lastHour = -1;
    private void OnElapsedTime(object source, ElapsedEventArgs e)
    {
        var curTime = DateTime.Now; // Get current time
        if (lastHour != curTime.Hour && curTime.Minute == 5) // If now 5 min of any hour
        {
            lastHour = curTime.Hour;

            // Some action
            this.WriteToFile(" interval start {0}");
        }
    } 
}
