示例1: Main
//引入命名空间
using System;
using System.Threading;
public class Example
{
public static void Main()
{
// Create an instance of the Example class, and start two
// timers.
Example ex = new Example();
ex.StartTimer(2000);
ex.StartTimer(1000);
Console.WriteLine("Press Enter to end the program.");
Console.ReadLine();
}
public void StartTimer(int dueTime)
{
Timer t = new Timer(new TimerCallback(TimerProc));
t.Change(dueTime, 0);
}
private void TimerProc(object state)
{
// The state object is the Timer object.
Timer t = (Timer) state;
t.Dispose();
Console.WriteLine("The timer callback executes.");
}
}示例2: Main
//引入命名空间
using System;
using System.Threading;
class TimerExample
{
static void Main()
{
// Create an AutoResetEvent to signal the timeout threshold in the
// timer callback has been reached.
var autoEvent = new AutoResetEvent(false);
var statusChecker = new StatusChecker(10);
// Create a timer that invokes CheckStatus after one second,
// and every 1/4 second thereafter.
Console.WriteLine("{0:h:mm:ss.fff} Creating timer.\n",
DateTime.Now);
var stateTimer = new Timer(statusChecker.CheckStatus,
autoEvent, 1000, 250);
// When autoEvent signals, change the period to every half second.
autoEvent.WaitOne();
stateTimer.Change(0, 500);
Console.WriteLine("\nChanging period to .5 seconds.\n");
// When autoEvent signals the second time, dispose of the timer.
autoEvent.WaitOne();
stateTimer.Dispose();
Console.WriteLine("\nDestroying timer.");
}
}
class StatusChecker
{
private int invokeCount;
private int maxCount;
public StatusChecker(int count)
{

}
// This method is called by the timer delegate.
public void CheckStatus(Object stateInfo)
{
AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
Console.WriteLine("{0} Checking status {1,2}.",
DateTime.Now.ToString("h:mm:ss.fff"),
(++invokeCount).ToString());
if(invokeCount == maxCount)
{
// Reset the counter and signal the waiting thread.
invokeCount = 0;
autoEvent.Set();
}
}
}输出：
