程序已在運行時，在設定的時間調用方法？

Question

我試着如果程序是用C銳利和創建一個Windows窗體

我開始了使用timer設置爲1運行

林找到一些代碼，將在13:00小時運行的方法分鐘，當timer_tick我嘗試過的if statement嘗試

if (TimeDate.Now == new DateTime(0001, 01, 01, 08, 00)) 

乾杯

Answer 1

使用System.Threading.Timers.Timer對象;

運行計時器，開始所需時間的下一個實例，此後每24個實例。

// TimerCallback object that wraps your method to call when timer elapses 
// (see end of answer) 
var tc = new TimerCallback(DoStuffAt1300Hours); 

// Tomorrow 2/25/14 at 1pm 
var dt = new DateTime(2014, 2, 25, 13, 0, 0); 

// dt - DateTime.Now = start timer in whatever time is between now and tomorrow at 1pm 
// This is a delay, so effectively, the timer will start tomorrow at 1pm 
// And it will run every 24 hours, calling the method DoStuffAt1300Hours() 
var timer = new Timer(tc, null, dt - DateTime.Now, TimeSpan.FromHours(24)); 

創建一個將執行你想要的回調;

public static void DoStuffAt1300Hours(object o) 
{ 
    Console.WriteLine("Hey it's 1pm!"); 
}
