如何在C#控制台应用程序中添加计时器?

可以通过C#第三版从同一本书CLR中看到这种修改。

using System;
using System.Threading;

public static class Program {

   public static void Main() {
      // Create a Timer object that knows to call our TimerCallback
      // method once every 2000 milliseconds.
      Timer t = new Timer(TimerCallback, null, 0, 2000);
      // Wait for the user to hit <Enter>
      Console.ReadLine();
   }

   private static void TimerCallback(Object o) {
      // Display the date/time when this method got called.
      Console.WriteLine("In TimerCallback: " + DateTime.Now);
      // Force a garbage collection to occur for this demo.
      GC.Collect();
   }
}

使用System.Threading.Timer类

using System; 
using System.Threading; 
public static class Program 
{ 
    public static void Main() 
    { 
       Console.WriteLine("Main thread: starting a timer"); 
       Timer t = new Timer(ComputeBoundOp, 5, 0, 2000); 
       Console.WriteLine("Main thread: Doing other work here...");
       Thread.Sleep(10000); // Simulating other work (10 seconds)
       t.Dispose(); // Cancel the timer now
    }
    // This method's signature must match the TimerCallback delegate
    private static void ComputeBoundOp(Object state) 
    { 
       // This method is executed by a thread pool thread 
       Console.WriteLine("In ComputeBoundOp: state={0}", state); 
       Thread.Sleep(1000); // Simulates other work (1 second)
       // When this method returns, the thread goes back 
       // to the pool and waits for another task 
    }
}
