如何实现定时提醒
具体通过什么实现。。

[易企加_天马行空]

用System.Threading.Timer
设定间隔时间，到时间执行提醒操作就可以了。

using System;
using System.Timers;

public class Timer1
{
public static void Main()
{
// Normally, the timer is declared at the class level, so
// that it doesn't go out of scope when the method ends.
// In this example, the timer is needed only while Main
// is executing. However, KeepAlive must be used at the
// end of Main, to prevent the JIT compiler from allowing
// aggressive garbage collection to occur before Main
// ends.
System.Timers.Timer aTimer = new System.Timers.Timer();

// Hook up the Elapsed event for the timer.
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

// Set the Interval to 2 seconds (2000 milliseconds).
aTimer.Interval = 2000;
aTimer.Enabled = true;

Console.WriteLine("Press the Enter key to exit the program.");
Console.ReadLine();

// Keep the timer alive until the end of Main.
GC.KeepAlive(aTimer);
}

// Specify what you want to happen when the Elapsed event is
// raised.
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
//execute your alert.
Console.WriteLine("Hello World!");
}

楼上已经很详细了。
在看下你自己的需求咯。
一般都用timer来实现的，或者你可以写个线程，死循环的读取现在的时间来进行判断。^_^。
如果说的什么不对，提出下啊，我比较菜。
