c#实现每隔一段时间执行代码(多线程)

方法一:调用线程执行方法,在方法中实现死循环,每个循环Sleep设定时间;

方法二:使用System.Timers.Timer类;

方法三:使用System.Threading.Timer;

using System;
using System.Collections;
using System.Threading;
 
public class Test
{
 
    public static void Main()
    {
        Test obj = new Test();
        Console.WriteLine(Thread.CurrentThread.ManagedThreadId.ToString());
 
        //方法一:调用线程执行方法,在方法中实现死循环,每个循环Sleep设定时间
        Thread thread = new Thread(new ThreadStart(obj.Method1));
        thread.Start();
 
 
        //方法二:使用System.Timers.Timer类
        System.Timers.Timer t = new System.Timers.Timer(100);//实例化Timer类,设置时间间隔
        t.Elapsed += new System.Timers.ElapsedEventHandler(obj.Method2);//到达时间的时候执行事件
        t.AutoReset = true;//设置是执行一次(false)还是一直执行(true)
        t.Enabled = true;//是否执行System.Timers.Timer.Elapsed事件
        while (true)
        {
            Console.WriteLine("test_" + Thread.CurrentThread.ManagedThreadId.ToString());
            Thread.Sleep(100);
        }
 
 
        //方法三:使用System.Threading.Timer
        //Timer构造函数参数说明:
        //Callback:一个 TimerCallback 委托,表示要执行的方法。
        //State:一个包含回调方法要使用的信息的对象,或者为空引用(Visual Basic 中为 Nothing)。
        //dueTime:调用 callback 之前延迟的时间量(以毫秒为单位)。指定 Timeout.Infinite 以防止计时器开始计时。指定零 (0) 以立即启动计时器。
        //Period:调用 callback 的时间间隔(以毫秒为单位)。指定 Timeout.Infinite 可以禁用定期终止。
        System.Threading.Timer threadTimer = new System.Threading.Timer(new System.Threading.TimerCallback(obj.Method3), null, 0, 100);
        while (true)
        {
            Console.WriteLine("test_" + Thread.CurrentThread.ManagedThreadId.ToString());
            Thread.Sleep(100);
        }
 
        Console.ReadLine();
    }
 
 
    void Method1()
    {
        while (true)
        {
            Console.WriteLine(DateTime.Now.ToString() + "_" + Thread.CurrentThread.ManagedThreadId.ToString());
            Thread.CurrentThread.Join(100);//阻止设定时间
        }
    }
 
 
    void Method2(object source, System.Timers.ElapsedEventArgs e)
    {
        Console.WriteLine(DateTime.Now.ToString() + "_" + Thread.CurrentThread.ManagedThreadId.ToString());
    }
 
 
    void Method3(Object state)
    {
        Console.WriteLine(DateTime.Now.ToString() + "_" + Thread.CurrentThread.ManagedThreadId.ToString());
    }
}
