如果想延时2秒执行一个方法，且只执行一次。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace ConsoleThreadTimer
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("HELLO");

            System.Threading.Timer _thdTimer = new System.Threading.Timer(new TimerCallback(TimerProc),
                "0",2000, Timeout.Infinite);
            Console.ReadKey();

        }

        private static void TimerProc(object state)
        {
            try
            {
                string s = state.ToString();
                Console.WriteLine("threading timer tick:"+ s);
            }
            catch (Exception ex)
            { }
        }
    }
}
