C# Timer Usage Explained

In C#, you can create and use timers using the System.Timers.Timer class. Here are the basic steps for using a timer in C#.

1. Instantiate a Timer object:

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

1. Set the interval time of the timer (in milliseconds):

timer.Interval = 1000; // 设置为1秒

1. Write a method to handle timer events and bind it to the Elapsed event.

timer.Elapsed += TimerElapsedEventHandler;

1. Start the timer.

timer.Start();

1. Define methods for handling timer events.

private static void TimerElapsedEventHandler(object sender, ElapsedEventArgs e)
{
    // 在此处编写计时器触发时的操作
}

By following these steps, you can create and use a timer in C# to perform periodic or delayed operations. Remember to stop the timer promptly when it is no longer needed to release resources.
