實現該功能用到的是System.Timers.Timer

將定時的方法新增到Global.ascx.cs中

public class Global : System.Web.HttpApplication

    {

        protected void Application_Start(object sender, EventArgs e)

        {

                //在應用程式啟動時執行的程式碼

                System.Timers.Timer myTimer = new System.Timers.Timer(); // 每個一分鐘判斷一下，單位為毫秒

                myTimer.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent); //執行需要操作的程式碼，OnTimedEvent是要執行的方法名稱

                myTimer.Interval = AutoUpdateGoldPriceTime;

                myTimer.Enabled = true;

            }

        }

        protected void Session_Start(object sender, EventArgs e)

        {

        }

        protected void Application_BeginRequest(object sender, EventArgs e)

        {

        }

        protected void Application_AuthenticateRequest(object sender, EventArgs e)

        {

        }

        protected void Application_Error(object sender, EventArgs e)

        {

        }

        protected void Session_End(object sender, EventArgs e)

        {

        }

        protected void Application_End(object sender, EventArgs e)

        {

        }

        protected  void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e)

        {

        //需要定時執行的邏輯

        }
