退出后仍在内存中的C#控制台应用程序-异步Web服务

我真的是C#和.Net的新手。我的老板让我使用web服务创建一个使用异步回调的计时器。我确实创建了它，并使其工作，但每当我关闭控制台应用程序窗口时，web服务仍在运行。当我重新运行应用程序时，它会从0开始计数器，但会来回跳到上一次运行的数字（仍在记忆中）。

mainMethod（）每10秒将数字递增1，monitorMethod（）读取该数字并返回一个字符串。

如何停止web服务，并在每次关闭控制台窗口时将计数器重置回0？

我希望这是有道理的！提前感谢！

这是我的密码。

 public class Service1 : System.Web.Services.WebService
 {
    private int iTotal;
    private int iCurrent;
    [WebMethod]
    public void mainMethod()
    {
        iTotal = 42;
        iCurrent = 1;
        Application["iTotal"] = iTotal;
        Application["iCurrent"] = iCurrent;
        // sleep 10 seconds
        while (iCurrent <= iTotal)
        {
            Application["iCurrent"] = iCurrent;
            iCurrent++;
            System.Threading.Thread.Sleep(10000);                
        }
    }
    [WebMethod]
    public string monitorMethod()
    {
        iCurrent = int.Parse(Application["iCurrent"].ToString());
        iTotal = int.Parse(Application["iTotal"].ToString());
        if (iCurrent <= iTotal)
        {
            return iCurrent + " of " + iTotal;
        }
        else
            return "DONE";
    }
  }
}
