運行方法幾次，並延遲幾秒

Question

在我的控制檯應用程序下方的while循環中，調用GenerateRandomBooking()方法5次然後延遲GenerateRandomBids() 2-3秒的最佳方式是什麼？

private static void Main() 
    { 
     SettingsComponent.LoadSettings(); 

     while (true) 
     { 
      try 
      { 
        GenerateRandomBooking(); 
        GenerateRandomBids(); 
        AllocateBids(); 
        Thread.Sleep(TimeSpan.FromSeconds(5)); 
      } 
      catch (Exception e) 
      { 
       Console.WriteLine(e.ToString()); 
      } 
     } 
    } 

Answer 1

大約是這樣的

private static void Main() 
{ 
    SettingsComponent.LoadSettings(); 

    while (true) 
    { 
     try 
     { 
      for(int x=0; x<4 ; x++){ 
       GenerateRandomBooking(); // Will call 5 times 
      } 

      Thread.Sleep(2000) // 2 seconds sleep 

      GenerateRandomBids(); 

      AllocateBids();   
     } 
     catch (Exception e) 
     { 
      Console.WriteLine(e.ToString()); 
     } 

    } 
}

使用 Thread.Sleep()

是什麼幾乎總是一個壞主意。我相信這是更好的使用計時器：

System.Timers.Timer timer = new System.Timers.Timer(); 

timer.Interval = 2000; 
timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); 
timer.Enabled=false; 
void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)  
{ 
    timer.Enabled=false; 
} 

private static void Main() 
{ 
    SettingsComponent.LoadSettings(); 

    int counter =0; 

    while (true) 
    { 
     try 
     { 
      GenerateRandomBooking(); 
      GenerateRandomBids(); 
      AllocateBids(); 
      counter ++;    

      if(counter > 4){ 
       timer.Enabled=true; 
       while (timer.Enabled) 
       { 
        ///wait time equal to timer interval... 
       } 
       counter=0; 
      } 
     } 
     catch (Exception e) 
     { 
      Console.WriteLine(e.ToString()); 
     } 

    } 
}
