Timer类属于System.Timers命名空间，在下文中一共展示了Timer类的4个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的C#代码示例。

示例1: Main

//引入命名空间
using System;
using System.Timers;

public class Example
{
   private static System.Timers.Timer aTimer;
   
   public static void Main()
   {
      SetTimer();

      Console.WriteLine("\nPress the Enter key to exit the application...\n");
      Console.WriteLine("The application started at {0:HH:mm:ss.fff}", DateTime.Now);
      Console.ReadLine();
      aTimer.Stop();
      aTimer.Dispose();
      
      Console.WriteLine("Terminating the application...");
   }

   private static void SetTimer()
   {
        // Create a timer with a two second interval.
        aTimer = new System.Timers.Timer(2000);
        // Hook up the Elapsed event for the timer. 
        aTimer.Elapsed += OnTimedEvent;
        aTimer.AutoReset = true;
        aTimer.Enabled = true;
    }

    private static void OnTimedEvent(Object source, ElapsedEventArgs e)
    {
        Console.WriteLine("The Elapsed event was raised at {0:HH:mm:ss.fff}",
                          e.SignalTime);
    }
}
开发者ID:.NET开发者，项目名称:System.Timers，代码行数:37，代码来源:Timer

输出：

Press the Enter key to exit the application...

The application started at 09:40:29.068

The Elapsed event was raised at 09:40:41.117
The Elapsed event was raised at 09:40:43.132
The Elapsed event was raised at 09:40:45.133
The Elapsed event was raised at 09:40:47.148

Terminating the application...


示例2: Main
